Thunderbird's color labels
I am trying to find where cyrus imap stores the colors Thunderbird uses in the message index display. I thought they were probably custom flags and I could use mbexamine to find them. I have a mailbox that has this in the first stanza from mbexamine, which looked promising-- User Flags: $label1 $label2 $label3 $label4 $label5 $Forwarded Redirected Each message has a line with "> USERFLAGS" but those are mostly four groups of zeros, and the values do not correspond to the Tbird colors. What else can I try? -- Joseph Brennan Lead, Email and Systems Applications Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
Re: Mailboxes messed up after migration
IMAP provides two kinds of timestamp: the time the message was placed into the mailbox, and the time in the Date header line. In a typical inbox and sent mailbox the two are the same order. In other folders it might not be the same. I think Roundcube uses the first kind of timestamp, which for cyrus is not a sort at all since it is the internal order of messages in a mailbox. I guess the question is whether the migration moved messages out of order, or whether the users are noticing something that was true before migration.

True, but it's breaking the Internet Message Format RFC, namely RFC 2822. Under "Obsolete Syntax" includes this: Finally, certain characters that were formerly allowed in messages appear in this section. The NUL character (ASCII value 0) was once allowed, but is no longer for compatibility reasons. Compatibility with POP and IMAP, presumably. Sendmail seems to be following still the old "be generous in what you accept" maxim, and as a result it accepts something that modern software cannot read-- just in case you have some odd way of reading mail that can handle it. -- Joseph Brennan Columbia University Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus

It should be able to subscribe and unsubscribe folders that do not exist, and the server "MUST NOT unilaterally remove an existing mailbox name from the subscription list even if a mailbox by that name no longer exists", quoting RFC 3501 (IMAPv4), section 6.3.6 which explains the reason behind it. Of course there are cases in client-server systems where one breaks protocol on one side to cope with software that breaks protocol on the other!

The SMTP maximum is 1000 including the CR LF pair. I'm surprised a message like that is accepted by your MTA and/or LMTP. If Cyrus IMAP handles up to 2047 characters that's very generous.

To be precise, a client creates the sent mail copy by writing it to the folder with IMAP. That copy is not delivered by SMTP or LMTP. What makes this idea a hopeless task, in my opinion, is that each client has its own name for the sent folder. Sent, Sent Mail, Sent Messages, and sent-mail, are the most common but not a full list.

Re: IMAP Flags clarification.
\Seen is an IMAP flag. Unseen means "Messages that do not have the \Seen flag set." I don't know what "high priority" means in this context. If you mean headers like "Priority: Urgent" or "X-Priority: 1", those are not IMAP flags. And for that reason I don't know what Michael Slusarz means by the order in which the server returns the flags. Evidently Horde IMP can show only one of the two things, but whether it prefers an IMAP state to the content of a header sure seems to me like an IMP client-side decision. I am probably missing something here.

Re: cyrus.index file
> how can I check if a user deleted a mail ? > Is there is history somewhere? > How can I read the cyrus.index file? If it's not expunged, only marked deleted, give your account lrs on the mailbox temporarily and open it with a client. I find that a very usable way to read the cyrus.index :-) If it's expunged, if you use delayed expunge and it was expunged within the delay period, unexpunge -l user.xxx will show it. If neither, you might be able to make a guess based on the known delivery time (from postfix logs) and timestamps on the message files on the file system. E.g. postfix says it was delivered at Nov 1 10:25, and you have in the mailbox message 4566. at 10:10, no message 4567., and message 4568. at 10:30... conclusion, it was there and was deleted and expunged.

Judging by the last delivery date is compromised by spam. Getting mail unfortunately does not mean the account is being used. Judging by seen state is much better provided you can assume IMAP. I don't think POP updates seen. But POP devices tend to check in regularly, so you could cover obvious cases by checking the last couple of weeks of system log. It won't be perfect.

It's the only way to restore ALL mail, since backups miss anything that came and went between backups. The additional storage is only for storing messages expunged in the past N days. A short 7 days meets most needs, and also, then your backups would be complete.

There can be a null namespace. We use it for one's own mailboxes.--

So "shared.testshared" is subscribed, but roundcube prefixes "INBOX."
to that? Is that configured into roundcube?
Does LSUB return the right names? Given the above, I expect your own
folders to have names starting "INBOX." and the shared folders to
have just their names.
(
On our system, my own folders are in the null namespace:
* LSUB () "." "Words"
while a shared folder has the prefix we established:
* LSUB () "." "~ Public Folders.bboard"

The files could be on a slower type of disk drive than you need for email storage. You could write code choosing which attachments to do this to, say by size or file extension. A mechanism to remove the files is not provided, but it's suggested that recipients would need to download the attachment to their own computer and that therefore the files could be deleted by a cron job based on age. I mention this only as another way to do it. Note that this could be implemented for outgoing mail too. We have not implemented it here so I can't say more than that it is possible.

Holy expletive. By the time cyrus gets the message, you have lost the envelope sender and envelope recipients. So you can't send any type of delivery status notice correctly, whether vacation replies, bounces, or receipts. It looks like you can't deliver bcc'd messages either, if you are trying to guess recipients by reading headers. Anyway none of this is a cyrus problem. I'm out of here.

Check this by looking at your syslog or maillog, for an outgoing message from <> to the hotmail address. It will be within seconds of the incoming message from the hotmail address. Actual delivery to the hotmail inbox is not your concern, and from stories I've heard, don't count on it to work. The hotmail user may have a user-level configuration that throws the mail away, without realizing it. If there are any other rules in the sieve filter before the vacation rule, check whether they say to stop. For example, if I say put mail from f...@example.com in inbox and stop, and then have the vacation rule after that, f...@example.com won't get the vacation message. You know of course that vacation replies per sender only once a day, or some longer period, right? Just checking.

"Expunge" comes from the MM client developed in the 1970s. One of the developers, Mark Crispin, designed the IMAP protocol in 1986, and he carried over the term Expunge as the command to remove messages marked deleted. <http://www.columbia.edu/acis/email/mm.home/mmmanual/8.about.mm.html> I can't think of a good reason not to use the term that the protocol uses, since it is a word people know and using it would make it simpler to discuss commands applicable to any IMAP client. I first saw "purge" used in the mid 1990s. I don't know whether it first appeared in the Exchange Client (the interoffice memo and scheduling client that became Outlook) or Netscape Navigator (one the first GUI IMAP clients). It was an unfamiliar term and I did not understand why it was being used. None of the old email clients used it, nor did the POP or IMAP protocols.

It marks the messages deleted. You can still undelete them, in case of error. Then the command "expunge" removes all messages marked deleted.

See system log ; diff the Received headers and Message-ID. Most likely it was sent twice, indicating a sender client problem. If sent only once, find out whether the message is really repeated on the cyrus server. Grep the Message-ID. If it's there only once, it's some kind of index problem on cyrus or in the client.

Re: limit tcp sessions opened by an IMAP client
Strange to see so many logins spread over a short time. They seem to be in pairs, which is the way some clients start up. I wonder if the client thinks the connection has dropped, and so it starts new sessions. I realize the server's netstat shows them as still connected. It might be interesting to log sessions and see what's going on. Or to strace live processes. And of course ask the user what it looks like from his/her end.

Since the copy failed, Squirrelmail did not send the delete command, and you don't know whether it would have worked. It would be simpler to debug if you configure Squirrelmail to just mark deleted when you tell it to delete-- no Trash. Second, stop doing ls on the filesystem. What you need to know about is Cyrus mailboxes and permissions-- not what's on the unix filesystem. Use cyradm to find out whether there is a mailbox called user.satimiscyrus.Trash, and if not, find out whether the ACL on user.satimiscyrus allows the user to create subfolders (the "c" permission). It would be weird for a user not to have permission to create subfolders of his own folders. That's probably not it. But you've been mucking around, so check. More likely COPY failed because Trash does not exist. Have the user create Trash with imap and see if that fixes it. Or use cyradm to create user.satimiscyrus.Trash. I assume that when Squirrelmail refers to INBOX.Trash it actually means a mailbox called Trash under user.satimiscyrus.

Depending on how your system is set up, cyrus may have no way to verify who is sending mail, and would need to see that "anyone" has the "p" permission. This is no different than for any mailbox. All inboxes have an implicit "anyone p". > 2)How do you delete an entry from the bulletin board folder? > Since I had all rights I deleted a test mail I got into the folder by > dragging and dropping it in evolution.

Someone with the "d" permission can mark it deleted, and then expunge. I cannot think of any way to duplicate what you describe. It sounds like evolution is showing you something different from what is on the server, which would be pretty bad. Maybe you could check by reading with a different client, or from a different computer, using your own account, or even better, learn how to type imap commands from telnet so you can get a view without a client.

Matt Garretson <[EMAIL PROTECTED]> wrote: > Along similar lines, any well-written Procmail recipe which redirects > mail typically checks for, or adds, an "X-Loop" header before > forwarding anything. Yes, it's an old solution. The crucial difference is that if one writes a bad procmail recipe, the message loops round and round until one of the MTAs considers the hop count exceeded and bounces it to sender, but if one writes a bad sieve rule, the message _is silently lost_. That's a much harsher penalty. And we stand a chance of here of doing _better_ than procmail. If we insert a header roughly like 'X-Sieve-Seen: user hostname' when we forward, we can look for it in incoming messages and say we won't forward again. So the penalty for writing a bad sieve forward rule would be that it doesn't forward. That's better than bounce to sender, and way better than losing the message. > If the "editheader" Sieve extension gets implemented, then a well- > written sieve script should be able to do the same type of thing. > To me this seems a bit more sane than expecting lmtp or sieve to > accomplish it automatically.

In case [1], user X forwards to an external address which forwards back to user X. This could be solved by not suppressing duplicates when forwarding to external addresses. Instead the loop would be stopped by exceeding the hop count in the MTA, and the MTA would bounce. This emulates what happens with .forward or .procmailrc loops. In case [2], user X forwards to user X. If lmtpd hands this to the MTA, it's like case [1]. Or does lmtpd handle this by itself? In that case the loop should be detectable, I imagine. I'm probably missing something. We might be smarter with case [1] if lmtpd inserted a "X-Been-Here" type header as it hands off to the MTA, so that it could detect a loop the first time the message comes back.

Hm. What if duplicate suppression is turned off? Infinite loop? Hop count is the classic MTA method of detection, but here the very first time around the loop will hit dup suppression. This calls for something else that lets the system know the message already passed through a local sieve script.

As stated, normally done at the MTA level. But note also, normally done by total message size, not attachment size. If you have to analyze mime parts and measure the size of each one, half the battle is lost already, that is the sender already transmitted the large message and you had to store it in a spool file and parse it. At MTA level, if you and the sender both use ESMTP, your MTA can state its maximum message size in the ehlo response, and the sender's MTA can see that and not even send the message. That is the best outcome. If the sender does not use ESMTP, it wastes time sending the entire message, but you can still reject quickly. The sender's MTA will create the bounce notice, or do whatever else it does when mail can't be delivered. The Cyrus system should not send a bounce. It should only accept or reject, and the sending MTA should handle notifying the sender.

This is a necessity for us too, if we are to integrate the Exchange and Cyrus systems. One of the interesting things about Open-Xchange is support for push via SyncML. There is a list of PDAs that it works with. The devices we support now need the intermediaries of either GoodLink or BES attached to Exchange, and if I understand it right (I might not), they use a MAPI connection to find out when there is new mail. If so it appears they would work also with systems like Open-Xchange that offer MAPI connections.

But analyzing the old file structure is not difficult to script. "find" gives a nice list. "if (-z $file || -d $file)", just create a Cyrus mailbox but skip the message moving tool. Detail will vary depending how the old mail was structured. We had to grab /var/spool/mail/user, ~user/mbox, and ~user/mail/* which might be common in U Wash for example.

It's less painful if you can use Cyrus to do this stuff. I know :-) The main reason you might have to do this would be restoring entire mailboxes off backups. Given /var/mail/j/user/janedoe/folder1/folderA , Cyrus might have three mailboxes named user.janedoe, user.janedoe.folder, and user.janedoe.folder.folderA, but not necessarily. cyradm will show you what folders exist, in Cyrus's view, and it lets you create, delete, and rename mailboxes to make the Cyrus view be what you want it to be. Cyrus will move the files around in the filesystem accordingly. To do batch work a perl script can use Cyrus::IMAP::Admin to do what cyradm would do. When we migrated from mbox, we created Cyrus mailboxes for the directories too. For ~janedoe/mail/foo/bar (mbox file) we created both user.janedoe.foo and user.janedoe.foo.bar, even though the user had never stored mail in foo (since it was a directory). This seemed simpler than having to explain later that foo could be part of a mailbox name but not exist as a mailbox!

They really do exist only on the replica. The replica does not report to the master (if it did, it would fight with the primary about where mailboxes are). Therefore, the following do not change the master: running cyradm on the replica and doing deletemailbox; and deleting the mailbox with an imap client. I have a list of them from running ctl_mboxlist -d on the master. But I can't figure how to remove them from the master's mailbox list. Does anyone have an idea?

Re: Bare newlines problem

How can I remove these bare newlines? It's a big message with foto's, 3.5 MB. I am not sure this warning is correct. I allready tried a perl-script of Joseph Brennan what I found in this list, but it did not change the message (checked with diff). The script prepares mbox-format mailboxes for mailutil, which complains if there are CR characters (\015) in the mbox-format files. It changes CRLF to LF and then changes remaining CR to LF. Bare LF is normal for unix files. Are you sure it says "bare newlines"? Newline is an ambiguous term.

Re: POP3 to CyrusIMAP migration howto ?

Each user would have to run a client that can move messages from the local inbox to the Cyrus server. You cannot do it for them unless you have some kind of remote access to all the PCs (which might be the case in a controlled corporate environment).

Exchange's handling of Sieve Reject
Users on two separate Exchange servers here have reported that they
don't see the reason part of messages rejected by sieve.
The Cyrus user has a reject rule. I can reproduce it simply as:
##INGO
# sieve filter generated by Ingo (March 14, 2007, 8:51 am)
require "reject";
# Sieve Reject Test
if header :comparator "i;ascii-casemap" :contains "Subject" "please reject
this message" {
reject "You want it rejected, you get it rejected.";
stop;
}
-
To see precisely what is returned, send mail to [EMAIL PROTECTED] with
the subject "please reject this message". The mime message looks
syntactically correct to me, as follows:
main message is multipart/report
part 1 is text/plain
part 2 is message/disposition-notification
part 3 is message/rfc822
The Exchange messages were viewed with Outlook. Outlook users did not
see any of the message sent by Sieve, but only a new text generated by
Exchange or Outlook that looks like this:
-
From: Mail Sieve Subsystem [mailto:[EMAIL PROTECTED]
Sent: Tuesday, March 13, 2007 5:20 PM

One of our staff looked at one of the message also with Evolution, and
reported a *variant* form of the above message, making me wonder what
data Exchange is sending to the client. It looks like this:
-
Your message

Subject: test attachment

Content-Transfer-Encoding: 7bit
Final-Recipient: RFC822; [EMAIL PROTECTED]
Disposition: automatic-action/MDN-sent-automatically; deleted
Original-Message-ID:
<[EMAIL PROTECTED]>
-
Notice the changes in the line spacing, the Sent: line, the "was" line,
and the inclusion here of the text from mime part 2. Evolution also
indicated the presence of a dat attachment after this, which the Outlook
users did not see.
We did not yet test what Outlook shows when it reads as an imap client
off the Cyrus server. All the above was read off an Exchange server.
Possible fixes would be to format the rejection like a reply or a
forwarded message, or plain text, but it would be pretty dumb. Has
anyone else dealt with this at all? Any bright ideas?

reconstruct deletes messages
We're running into cases where running reconstruct removes message files, sometimes all of the messages in a folder, leaving only the directory and the cyrus.cache, cyrus.header, cyrus.index files. This makes no sense to me at all. I thought the only purpose of reconstruct is to rebuild the index. Under what circumstances would it unlink files?

Re: Moving mail into IMAP server and the Received date
--On Monday, February 19, 2007 16:32 +1000 RM <[EMAIL PROTECTED]> wrote: I've been experimenting with cyrus and some other imap servers which also exhibit this problematic behaviour: when I move the mail from a local folder to an imap folder under cyrus, my adjacent Windows/OutlookXp mail reader sorts the mail by "Received" date, and the date registered as "Received" is the time/date that the copy operation is carried out (ie: now) rather than the date that the mail was actually originally received. Outlook uses the internaldate attribute. RFC 3501 says: 2.3.3. Internal Date Message Attribute The internal date and time of the message on the server. This is not the date and time in the [RFC-2822] header, but rather a date and time which reflects when the message was received. In the case of messages delivered via [SMTP], this SHOULD be the date and time of final delivery of the message as defined by [SMTP]. In the case of messages delivered by the IMAP4rev1 COPY command, this SHOULD be the internal date and time of the source message. In the case of messages delivered by the IMAP4rev1 APPEND command, this SHOULD be the date and time as specified in the APPEND command description. All other cases are implementation defined. The relevant command is APPEND, and its description says: 6.3.11. APPEND Command Arguments: mailbox name OPTIONAL flag parenthesized list OPTIONAL date/time string message literal [ . . . ] If a date-time is specified, the internal date SHOULD be set in the resulting message; otherwise, the internal date of the resulting message is set to the current date and time by default. So when a client moves mail from local to server, it *could* send an internaldate. Cyrus honors this. When we moved from U Wash to Cyrus we were careful to get the internaldate from U Wash and send it in the append command to Cyrus. When the client does not send an internaldate, Cyrus follows the RFC and assigns the current date and time. There is no imap command to change internaldate once it has been assigned. Ideally you might be able to find a client that sends internaldate when it moves mail from local to server. The catch is that since so many clients, like Thunderbird, do not use internaldate to sort, they probably don't preserve it in local folders, and they probably don't try to reconstruct what it was from Received or Date headers when they append to a folder on server. It's not really a Cyrus or Outlook bug.
