[Dovecot] expire tool - individual user/folder?
by Andre Hübner 02 Jun '09

02 Jun '09

Hello, is the expire plugin usable to delete mails with different settings for each individual user? If i view sample config at http://wiki.dovecot.org/Plugins/Expire it looks like expire-data are related to foldernames. Is it possible to let each user "activate" the expire-plugin for different folders with different settings? Thanks, Andre

Did you try looking for the folders by connecting to IMAP using command line. telnet servername 143 a1 login username pass a2 list "" * Check if you could see anything.

[Dovecot] v1.1.16 released
by Timo Sirainen 02 Jun '09

02 Jun '09

http://dovecot.org/releases/1.1/dovecot-1.1.16.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.16.tar.gz.sig Fixes a couple of bugs in v1.1.15's changes. Hopefully the last v1.1 release before v1.2.0. - v1.1.15 could have crashed if mailbox-closing command was pipelined after a mailbox-accessing command. - v1.1.15's zlib plugin may have caused crashes when fetching INTERNALDATE. - Maildir: If messages had been deleted externally from new/ directory and mailbox was opened with EXAMINE, Dovecot didn't immediately notice that the messages were deleted. - If message body started with a space, some operations could have assert-crashed.

[Dovecot] recipient delimiter and lmtp
by John Fawcett 02 Jun '09

02 Jun '09

I read in the list archives about work in progress on an lmtp delivery agent.As a previous cyrus user where that was the preferred delivery method from postfix, this sounds interesting. I was wondering whether it will handle recipient delimiters. ie will it be able to map user+foo(a)example.com to user(a)example.com? I'm not interested in the delivery into folder stuff, just the plain delivery to inbox. thanks, John

[Dovecot] IMAP labeling sometimes not taken into account
by Olivier Cailloux 02 Jun '09

02 Jun '09

Dear Dovecot list, I recently switched from uw-imapd to dovecot to manage my huge mbox files (about 1 GB). I now observe a very strange behavior, difficult to reproduce reliably, which might be related to some misunderstanding on my part on how either dovecot works or imap labeling works. What I call "labeling" is the fact of marking some e-mail, in my e-mail client (currently Thunderbird), with a label, which can be chosen among five labels (plus the "no-label" case). Evolution also supports labeling. As far as I understood until a few days ago, when I put a label, say, number five, on an e-mail, a keyword "$Label5" is added on the "X-Keywords:" line of the corresponding e-mail in my mbox file. Removing the label simply removes the keyword on the same line. That is, at least, what happened with uw-imapd (not that I have seen that documented somewhere but this is what I observed). The label is thus stored on the e-mail server, not on the client hard disk, which is important for me as I extensively use that feature to sort e-mails, and need to access them from several different places (and find the same labels at the same places, naturally, whatever client I use). Since the change for dovecot, however, things are going strange. Sometimes the labels disappear for some reasons. Sometimes they stay there. And I can't reproduce the behavior, it just seems random. This is very annoying as it totally breaks my e-mail management. Currently there is something strange I can reproduce however, and if someone could explain me what is happening I guess it would be a good step towards a solution. I see a specific e-mail as being labeled in thunderbird, having label number five. I also tried with evolution, accessing the same imap folder, evolution also sees that e-mail as having a label number five. I tried running these clients from my imap server, and I tried thunderbird on a Windows box at home, and every clients agree: this e-mail has a "5" label. BUT when I open the mbox file directly on the imap server (using "less"), and scroll to that given e-mail, I see NO "X-Keywords: " line. How then can the e-mail clients know that this e-mail is labeled? Please note that this behavior does not happen with only one specific e-mail, but I take it as an example of what is strange. In fact I can see, especially at the end of the mbox file (thus the latest e-mails), that plenty of e-mails have either no "X-Keywords: " line or a line with "X-Keywords: " and nothing else, whereas they are seen as being labeled (and indeed I remember having labeled most of those through thunderbird). The former e-mails I checked in the m-box (for example, one month ago) all correctly have an X-Keywords line indicating "$Label5" or other appropriate labels. It seems like dovecot is keeping some track of labeled e-mails somewhere which is NOT in the mbox file, probably related to its indexing capabilities. But I don't know how that works and where these index files are stored, how to purge them and rebuild the index, and so on. Apparently these index files have remembered some e-mails as being labeled (which is good, because I indeed labeled them). But I'd like to know how that works to be able to better troubleshoot why sometimes the label disappear. Note that restarting dovecot does not change the label status of the e-mail, so the status must be stored somewhere on disk and not only in memory. Or is all these labeling stuff some unsupported, non-standard extension to IMAP that only uw-imapd supports? (I hope not because I find it very practical and I'd like to use it with dovecot as well!) Thank you for any help. (Technical informations follow.)

[Dovecot] Capability problems dovecot 2.0
by ja nein 01 Jun '09

01 Jun '09

Hi, I had some problems connecting TB 2.x with dovecot 2.0. TB2 complained about not being an IMAP4 server. TB 3 worked. It seems that dovecot 2.0 doesn't return capabilities when queried. Maybe some wrong config, thoug? Here are the debug logs from TB2 comparing dovecot 2.0 (not working) and dovecot 1.2 (working): Dovecot 2.0: NA:CreateNewLineFromSocket: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN AUTH=LOGIN AUTH=DIGEST-MD5 AUTH=CRAM-MD5] Dovecot ready.

[Dovecot] For the record: Postfix+Spamassassin+ClamAV+Dovecot
by James Butler 01 Jun '09

01 Jun '09

Postfix 2.5.5 SpamAssassin 3.2.5 (under Perl 5.10.0) ClamAV 0.95.1 Dovecot 1.2.rc2 works fine on Fedora 10. Installed Dovecot and ClamAV from source and everything else using yum. I'm using the ClamAV plugin for Spamassassin: http://wiki.apache.org/spamassassin/ClamAVPlugin I'm calling Spamassassin with: /etc/postfix/main.cf: mailbox_command = /usr/bin/spamc -f -e /usr/local/libexec/dovecot/deliver Postfix hands off to Spamassassin, which processes ALL mail (not just attachments) through the ClamAV plugin before parsing for spam, and then hands the whole mess off to Dovecot for 'deliver' to handle. How simple is that? Since ClamAV scanns all mail, it might be too processor-intensive for really large mail systems, but it is working great for our 120+ user system with lots of spam coming in. If you're using Procmail or some other preprocessor that can hand off to a pipe, then you could skip the plugin and pipe messages over a certain size (i.e. >1024) to clamd, instead. Enjoy! James
