[Dovecot] Not receiving Local Mails
Hi, I have already set up DOVECOT + POSTFIX mail server and I can send and receive mails outside my Domain. The problem however is that LOCAL Mail is not working. When I send LOCAL mails, it leaves my system without error messages but it is not received by the recipient. How do I make LOCAL mails work? Regards Alexander

With so many clues is difficult to say, but usually the problem is that the domain local mail uses is not a part of postfix's mydestination parameter. Anyway, look at postfix logs to see what's happening with local mail, and once you do it, you better ask in a postfix mailing list. HTH. -- Joseba Torre. Vicegerencia de TICs, área de Explotación

This division in two parts is more like a test... and if the dovecot can join again this two files in read time is good for me So you're thinking maybe you get better performance that way, or something? I was first thinking you'd want to add some automatic signature that gets modified once in a while, that wouldn't have worked. But yeah, you could do this with Maildir in a similar way than zlib plugin works. Instead of using i_stream_create_zlib(), you'd open the other file with i_stream_create_fd() and then make i_stream_create_concat() use both of the streams. Should be pretty easy to implement based on the zlib plugin code. Also when messages get expunged, you'd also need to delete the other file yourself. You can do that the same way as quota plugin decreases quota when message gets deleted. See http://wiki.dovecot.org/Design for more information about istreams and some other Dovecot code docs.

No, you don't need to implement a new istream, just ignore istream-zlib.c completely. Instead of the plugin calling i_stream_create_zlib, you just call i_stream_create_concat.

Re: [Dovecot] PostgreSQL connection bug
Let me make myself clearer. Dovecot opens a postgres connection, Dovecot sends a SELECT query using the connection, The response can be a) One or more rows of data b) Zero rows of data (eg if the username doesn't exist) c) An error response (eg if the query contains a syntax error) If a) or b) happens, then dovecot accepts or denies the user, and closes the connection. If c) happens, dovecot denies the user, but leaves the connection open (stuck). Next time someone tries to log on dovecot opens a new connection. This leads to a gradual buildup of connections until the limit is reached and stuff breaks. In my situation, the query was sometimes failing because the data sent was the wrong type (a string, when it should have been an integer - my fault). Hope that makes sense now. I think dovecot needs a line of code inserted to check whether the query failed, and if it did, log the error, and close the connection gracefully.

Re: [Dovecot] Overriding Default Subscription Behavior
On Thu, 2009-12-10 at 10:15 -0500, Tony Rutherford wrote: The subscription files we're migrating from have a . for folder separation. We will be using Dovecot's maildir with LAYOUT=fs. It's looking for / as the separator in the subscription file. So, obviously we could simply write a script to swap the two characters. However, just curious if there are any options for doing this within a plugin (since we're already doing some things in a plugin) by overriding some of the subscription code.something like the next_line() in subscriptions.c. I don't see any vfuncs in this area, aside from set_subscribed() I believe.but maybe there's a better spot I'm not thinking of? One thing I've learned with Dovecot is that it somehow supports things I didn't believe it could/would, so I thought I'd ask. Once you've moved to '/' separator, it's possible that users create mailboxes with '.' characters. So you can't just always keep converting all '.' to '/', you need to do it only once for each user. You could create a plugin that simply: 1) Check if subscriptions.converted file exists, if not continue: 2) Convert '.' to '/' in subscriptions and recreate it 3) Create subscriptions.converted file Or something like that. signature.asc Description: This is a digitally signed message part

[Dovecot] Sieve mails with decoded subject
Dear all,
I accidently posted this message to dovecot-news and want to apologize
for any trouble I may have caused. Here it is again to the correct
mailing list:
Recently I'm getting a ton of porn/viagra/diet/casino spam mails which I
tried to filter with sieve:
if header :contains Subject [ [SPAM],
Bett,
Schlafzimmer,
Spielen,
Luder,
abhenmen,
poppen,
Casino,
Bonus,
abnehmen,
Gewinn,
Potenz ] {
addflag \\seen;
fileinto Spam;
stop;
}
Sadly, this didn't work - taking a closer look upon one of the spam
mails, it seems the spamming rats have encoded the subject:
Subject: =?US-ASCII?B?RW5kbGljaCBtZWhyIGVuZ2FnZW1lbnQgaW0gQmV0dGNoZW4=?=
(reads: Endlich mehr engagement im Bettchen)
I'm thinking about filtering all such encoded subjects (as there's no
reason to encode them US-ASCII), but suppose it were UTF-8 or something:
how can I filter on the actual content, not the encoded subject? Surely
someone has solved that problem already?
Kind regards,
Johannes

[Dovecot] mail_max_userip_connections
What is the appropriate setting for mail_max_userip_connections ? My POP3 connections seem to be mostly 1 at a time, but my IMAP connections are often 3 per user per IP. Is this appropriate? If I change the IMAP setting to mail_max_userip_connections=1 will it break things for the user? I am trying to improve this situation: ps auxwww | grep imap | wc 2373080 22400 TIA, - Richard

Re: [Dovecot] Developer Documentation
Hi Timo
For tests i do it:
In src/lib-storage/index/maildir/maildir-mail.c
In the final of function maildir_open_mail i change the i_stream_create_fd
to this:
--- origin --
int fd = -1;
.
.
.
.
.
if (fd == -1) {
*deleted_r = TRUE;
return NULL;
}
input = i_stream_create_fd(fd, 0, TRUE);
index_mail_set_read_buffer_size(mail, input);
return input;
--
my
int fd = -1;
int fd1 = -1;
int fdp[2];
.
.
.
.
.
.
if (fd == -1) {
*deleted_r = TRUE;
return NULL;
}
do_open(mbox, /storage/emexis/
exemplo.com.br/messages/alex/Maildir/body_test, fd1);
fdp[0] = fd;
fdp[1] = fd1;
input = i_stream_create_concat(fdp);
index_mail_set_read_buffer_size(mail, input);
return input;
--
But the concat don't work.
I Try too create 2 streams and put this 2 fds in concat, not work too
-- my second

int fd1 = -1;

Ok ... i understand...
this is the last one...lol
in zib plugin i see a implementation of i_stream_create_zlib, this is a
substitution to the i_stream_create_fd , right ?
So, i need to do every think like in istream-zlib.c (close, destroy,
read, seek, stat and sync) to swap the original functions ?
No, you don't need to implement a new istream, just ignore istream-zlib.c
completely. Instead of the plugin calling i_stream_create_zlib, you just
call i_stream_create_concat.

This means it doesn't really exist, even though it's subscribed.
Do you know when/why this can happen?
The IMAP4rev1 spec specifically allows for a mailbox to be subscribed
without existing. The list of subscribed mailboxes has nothing to do
with the list of existing mailboxes (in other words, the results from
LSUB are not a subset of the results from LIST).

[Dovecot] Spam filtering (was: Re: Sieve mails with decoded subject)

That must have been a configuration issue - SpamAssassin works pretty well, if configured correctly - but I admit, it's a monster (both in terms of configuration and resource usage). You could go for bogofilter (purely Bayesian). I'm using it for years on my private mail server with very good results. I like to use the tri-state filtering, where there is not only one threshold value, but two. A certainty of a mail being spam (bogosity) of 0.35 and below goes into my inbox, mails with a bogosity value between 0.35 and 0.65 go into Spam/Unsure, and everything above 0.65 goes directly into Spam. That way I have something like 10-20 mails per week in Spam/Unsure that are usually false negatives, rarely false positives (currently around 1000 mails per week end up in Spam). To my knowledge there has never been a false positive in Spam. Of course initial training is necessary. For ongoing training / feedback I have set up a Spam/Learn-Spam and Spam/Learn-Ham mailbox into which I move false negatives/positives. A cron script then runs the mails found in those (maildir) mailboxes through bogofilter again, with the command line option for classifying the mail as Spam/Ham and moves them to the correct mailbox (Spam/inbox) afterwards. This works well in all MUAs, because it only requires IMAP functionality to train the filter. The solution was inspired by a Gentoo Wiki article (http://www.gentoo-wiki.info/Bogofilter).

So I'd like to stick to KISS in this case. From what I've seen, SA has been extremely good and accurate for us. We use amavisd-new to interface, but SA is at the end of a long chain of checks. Between the (3) HELO checks, clamav-milter, and a SPF policy daemon, we're killing ~60% of all connections at SMTP time. (I analyzed that in November, instead of 65/day hitting my inbox I would've seen 6x that amount if it wasn't for those checks. So ~80% of all spam was getting blocked at SMTP time.) If we were to pay for the Spamhaus Zen list, we could probably boost that percentage to 90%. All of the domains we do business with get a -2 or -4 score using amavisd-new. Specific addresses get a larger negative score. I ran a few thousand spam ham messages at the SA bayes filter, then turned it on. We tag messages with a [spam] flag at 5.0 and quarantine at 9.0. Tagged messages go to the user's Inbox, quarantined messages get sieve'd into a sub-folder in the user's mailbox. So far (in a month), no false positives. Or at least none that people have complained were quarantined when they should not have been. I'm considering lowering the quarantine threshold next month. It's been nice to have my Inbox back, without 65 spams/day cluttering it up. Now I might see 2-5 per day that slip through without getting tagged as borderline spam (at 5.0 or higher). Those are mostly zero-day spam that haven't made it to the URIBLs or DNSBLs yet. I'm still debating grey-listing, Razor, DCC or paying for the Spamhaus Zen list. Compared to another, commercial, product that we were using a few years ago, SA is very very good. Not perfect, but really does a good job of classifying things with decent accuracy.
