Dovecot 2.2.21 change imap logout format (and broke my log parsing)
by Alessio Cecchi 23 Mar '16

23 Mar '16

Hi, after upgrade to dovecot-2.2.21 the log of "imap logout" format changed from: Mar 1 03:40:44 pop01 dovecot: imap(info(a)domain.com): Connection closed in=111 out=1522 session=<lusrsfMsXNVf79ju> to: Mar 3 03:48:11 pop01 dovecot: imap(info(a)domain.com): Connection closed (IDLE running for 0.001 + waiting input for 2088.878 secs, 2 B in + 10+0 B out, state=wait-input) in=224 out=2834 session=<6XTzihst3uUFqB6m> Can "(IDLE running for 0.001 + waiting input for 2088.878 secs, 2 B in + 10+0 B out, state=wait-input)" removed from the log? My imap_logout_format is: imap_logout_format = in=%i out=%o session=<%{session}> Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Allowing for multiple recipient_delimiter characters?
by Aaron Lindsay 23 Mar '16

23 Mar '16

Postfix allows the recipient_delimiter configuration parameter to contain multiple characters, splitting on the first such character it encounters. For example, if using 'recipient_delimiter=+-' both aaron+foo(a)example.com and aaron-bar(a)example.com would be delivered to aaron(a)example.com. Is anyone opposed to changing dovecot's handling of recipient_delimiter so that it's the same as that of postfix? If not, I am willing to rebase/merge/address review comments on Lennart Weller's patch[1] to get this functionality upstream. While I think aligning with postfix' behaviour would be convenient for those of us who run a server using both dovecot and postfix, would this break any other common use cases I'm not aware of? Thanks! -Aaron [1] - http://dovecot.org/pipermail/dovecot/2015-February/099660.html (I've talked with Lennart off-list, and he's OK with me working to get his patch merged, as long as I attribute his work to him, but doesn't have the time to work on it himself right now)

protocols.d/ dir empty?
by Kieran 22 Mar '16

22 Mar '16

(I hope I'm doing this right) Hey there. I have a problem with the dovecot protocols. When I do /telnet 127.0.0.1 143/ it gives me a connection refused error. I looked in the wiki and then after trying /doveconf protocols listen /I realized that I don't have any protocols.//I went in //usr/share/dovecot/protocols.d/ and it's empty. How can I fix that?

multiple imapc settings in different namespaces
by abi＠oleane.net 22 Mar '16

22 Mar '16

hello all i assume this question must have already been asked, but i'm looking for a way to circumvent which might work specifically on my system. the version can be any available version between 2.2.9 and 2.2.22 (i'm testing with both of the above and no other ) i'm using imapc in 2 different namespaces. in both cases, the imapc_host is local, and a custom passdb program is expected to handle proxying to different servers. one of the case should proxy to a different legacy platform, and the other is used for shared mailboxes. is there any way at all to be able to tell which is which in passdb ? i don't care about the password, i can use a login prefix or suffix, different ports, different master passwords, ssl, maybe a different protocol name or auth method... somehow i've seen in the source code there is a namespace "owner" but did not manage to change this parameter. i guess it is used internally. anything else ? thanks a lot for any help you can provide best regards @abi

It looks as if the backend tells the director/proxy about the full mailbox (552 5.2.2 <heiko(a)hs-example.de> Quota exceeded (mailbox for user is full)) already before the DATA phase starts, right as the response to the RCPT TO. But the proxy seems to ignore it… Any suggestion?

sieve - editheader - edit in place
by Hajo Locke 22 Mar '16

22 Mar '16

Hello, i do some tests with sieve editheader extensions. deleteheader and addheader are working, but i noticed that new headerlines are always prepended to current header. So new lines can be found always on top. I am looking for a possibility to edit a headerline in place, without moving the new line to top of stack(replaceheader?). It is not looking good if a Subject-Line suddenly moves to top of header. Is there a possibility for me? Thanks, Hajo
