Doesn't work in Samsung Email still. And with COPY FLAG set, it doesn't work with outlook either. You need APPEND for it to work in outlook. It currently works in outlook with either no causes restriction, or with COPY FLAG APPEND. But not in Samsung Email. And what I understand, leaving .causes out, should have it match ALL causes.

Re: Unable to disable TLSv1.3 or fallback to TLSv1.2 when 1 cipher is disabled
I have an operational need to disable TLSv1.3 due to inadequate support to exclude certain ciphers. There is no need to disable TLSv1.3 and attempts to do so will be flagged as “downgrade attacks”. Let us ignore TLSv1.2 as a downgrade option. And focus on TLSv1.3 for its entirety of this thread. If the ciphersuite (not cipher for that's a TLSv1.2 term), but a ciphersuite for TLSv1.3 needs to have its set of ciphers: * Reordered, or * disabled We cannot do it at the moment given this snapshot of Dovecot.

Dovecot v2.3.4.1 Debian 10.3 mbox format - Error: chdir(/var/spool/mail/domain/user) failed: Not a directory
Hi colleagues, I am trying to setup dovecot and have a strange problem. I configured it to: #dovecot -n|grep ^mail mail_gid = mail mail_location = mbox:/var/spool/mail/%d/mailboxes/%n:INBOX=/var/spool/mail/%d/%n mail_uid = mail And also setup exim4 to use it. I sent a test message and observe a mailbox file /var/spool/mail/domain/user, containing this message. But when I try to access dovecot with a client (thunderbird), client cannot fetch mail, and I observe error in the dovecot's log: May 09 23:35:51 imap(user@domain)<25179>: Error: chdir(/var/spool/mail/domain/user) failed: Not a directory What is it, and how to solve it? Thank you. Kind regards, Viktor
SV: Marking all emails in "Trash" as opened, and also prohibiting email clients from creating new ma
Another problem, is that running discard; on the Sent folder, just marks the
email for deletion - ergo it gets a strike-through.
It doesn't get deleted.
Tried with both Before and After.
Otherwise, the discard; on Sent folder works fine - ergo it only selects
emails that were written through IMAP, it doesn't select emails written from
appendfile in exim4, which is good.
So now I somehow need to get exim4 to actually delete the email completely
and not just mark it for deletion.

I tried with following:

if not hasflag :is "\\Seen" {
setflag "\\Seen";
}
And then this in plugins.conf:
plugin {
sieve_plugins = sieve_imapsieve
imapsieve_mailbox1_name = Trash

}
It works in outlook, the mail is opened (mark as read) when it goes to
trash.
But in Samsung Email it doesn't work.
(or it works when I select in Samsung email, "Move to Folder" and then
"Trash", but if I select "Delete", the mail is trashed without becoming
read)
(I have checked, the sieve script gets executed)

Dovecot version: 2.3.7.2 (3c910f64b)
(pkg shipped by: Ubuntu-Desktop 20.04)
I want to accomplish 2 things in dovecot:
1:
I want to force all mails inside Trash to have an "opened"/"read" flag
and "Non-Recent" flag. Basically Status: RO This regardless how the flag
appears, either by copying/moving the mail into trash, creating a new
mail in trash, flagging email in Trash or whatever.
Basically, no email in Trash should ever be able to have a recent or
unread flag.
I tried with a static mail filter and sieve filter to add \\seen to the
email upon COPY (as mentioned here:
https://dovecot.org/pipermail/dovecot/2017-November/110122.html ), but
regardless how I do it, it doesn't work when Samsung Email client
trashes an unread email, AND/OR also, it causes weird issues like
duplicate email in the trash folder sometimes.
Best would be some event filter that executes for every mail that
somehow end up in Trash, that checks if \\seen is present, if not, then
it will add it, on all emails in trash? But how I do to prevent the
duplicate copy that appears sometimes?
2:
I want to prohibit email clients from ever creating a new mail in Sent
folder.
If its possible to allow MOVE and/or COPY, it should be allowed, only
new mail should be prohibited.
(also note that external processes must be able to create new mail in
Sent)
HOWEVER - this prohibition must be silent - ergo the newly created email
is simply discarded. No error message or error codes should be returned
to IMAP client.
(The reason I want this, is because I have configured my outgoing SMTP
server to populate Sent, and some email clients doesn't have the option
to "Don't store a copy of the email in Sent folder" resulting in
duplicates)

converting old uucp buffer files to maildir
Hi *, besides my dovecot maildir structure, that has been migrated from an Exchange server, I have an even older mail structure in an ancient uucp style. The program named CrossPoint I used for this isn't wideley known, but it used so called mpuffer files in a plain text format. It is the program I still use to write for example this mail. I wonder if there already exists a program or script to convert the files from this program to the Dovecot maildir structure or some Howto for writing it myself. The format of these files looks like shown below.

Re: Ms Exchange vs dovecot
Hi Marc, >I have recently been working/testing with exchange 2016 and started >thinking if I should even migrate to this platform. I assume more people >here have experience with exchange and this idea. I was an Exchange admin for years and even had an Exchange server at home for about 20 years - just for fun and for testing purposes. Three months ago I migrated to dovecot and baikal - and dropped Exchange completely. This worked flawless, so *I* don't miss Exchange at all. But: You can't compare dovecot with Exchange, because dovecot is a mail server, Exchange is a groupware server. This is why I added a baikal server to my infrastructure. Baikal is a Cal- and CardDAV server, that can replace the calendar und contact parts of Exchange. Nevertheless you loose many features of an Exchange server after migrating to such a setup, so if your users got used to these feature, it wouldn't be possible to drop Exchange. It is only feasable for small environments with few people or in a new environment, where nobody has used an Exchange Server until now. IMHO. This was not your question, it is meant as background information, if you wouldn't already know that. For your environment I can't tell if it is possible to migrate to Exchange, because you didn't write, if you already have an Active Directory in place, which is necessary for Exchange on premise. If you want to use Microsoft's Azure AD and the Exchange cloud services on top, you have to migrate your users to Azure AD. In any case you need an Active Directory for Exchange server. >I was wondering if this is possible with a dovecot setup > 1. public folder can be implemented with a public mailbox?

RE: Ms Exchange vs dovecot
I was wondering about the sieve rules, because I thought they were executed during mail delivery in the lmtp process. You can also 'guess' this a bit from syntax of the rules or the single file they are stored in. Thus if you 'drag' messages between folders, they are not executed. Off topic: I know Exchange is a different solution. What I think is stupid, is that they store mail in a database still. Making it difficult to scale.

Re: Ms Exchange vs dovecot
First of all, Exchange is a complete solution. Dovecot is a imap/pop3 server ( a good one, sure... ) So replacing exchange means to find an integrated solution. about the questions: public folder was removed in exchange. IMHO they made the right choice :) There is a different thing, need different tools and different client app. You can create shared mailboxes ( i think it's a little demand for that, but yes) Sieve rules should work ( never tried actually) I can see a need for an integration with folders only when you work with webmail (like roundcube) .

So you can share files, edit etc using owncloud but also attach them and save them from webmail. You can find a lot of plugins in owncloud to deal with files, even editing with onlyoffice .

Not really since most GUI clients keep all the folders synced, so moving files to different, smaller count mailboxes doesn’t reduce the number of files accessed. The issue is if you have a folder with millions of files in it, most file systems don’t deal well with this. But with mbox, each “folder” is a single file, and making a single multi-GB text file that has to be parsed is a definitely issue on any file system. -- ALL WORK AND NO PLAY MAKES BART A DULL BOY ALL WORK AND NO PLAY MAKES BART A DULL BOY ALL WORK AND NO PLAY MAKES BART A DULL BOY Bart chalkboard Ep. 1F07
