[Dovecot] Dovceot user pop3 last connect info?
by Tim Tyler 04 Oct '07

04 Oct '07

Dovecot experts, I am a newbie to Dovecot. I am in the process of replacing qpopper with dovecot to support pop 3 clients. I have installed the latest version of Dovecot on Fedora Core 6. Everything seems to be working fine using ldap, etc. However, with qpopper, I used to have .pop.username files which would give me a time stamp of the last time a user established a pop3 connection. I know that Dovecot has logs of connection in the /var/log/maillog files, but these files rotate out over a relatively short period of time. Is there a method by which one can keep track of the last time a pop3 connection was established for each user when using Dovecot? Tim Tyler Network Engineer - Beloit College tyler(a)beloit.edu

[Dovecot] Namespace "hidden" option not working?
by Ed W 04 Oct '07

04 Oct '07

I either misunderstand the namespace hidden option, or else perhaps it's not working correctly in 1.0.5? dovecot.conf # default namespace namespace private { separator = / prefix = inbox = yes hidden = yes } # for backwards compatibility: namespace private { separator = . prefix = INBOX. inbox = yes } Then login and test s6jh LIST "" "*" SND: <<< len(939) Comp_len(118) Time:0.137985 * LIST (\HasNoChildren) "/" "Diary" * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Archive" * LIST (\HasNoChildren) "/" "Sent Items" * LIST (\HasNoChildren) "/" "Subdir" * LIST (\HasNoChildren) "/" "Junk E-mail" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "Drafts" * LIST (\HasNoChildren) "/" "Deleted Items" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "."

"INBOX" The idea was to support an old client using Courier like access whilst still letting new clients access using the normal process Ed W

[Dovecot] Disable imap proxy access
by Dominique Feyer 04 Oct '07

04 Oct '07

I work on a dovecot cluster (15 servers) we need to add a new storage array and move the data for a list of user from the old storage to the new one. We use dovecot proxy to redirect imap and pop3 to the same server everytime. How to disable pop3 and imap access during the data migration process (duration 5 minutes to 10 minutes). Can i send a custom error message to our users ? Thanks for your help Dominique Feyer

[Dovecot] In-site migration from /etc/passwd to LDAP
by Maykel Moya 04 Oct '07

04 Oct '07

I'm doing in-site migration of accounts from /etc/passwd to an LDAP directory. The migration should be progressive (not all users at the same time). I'm already able to check mail for accounts in /etc/passwd and accounts in LDAP. The problem is with mail delivery. I'm using Postfix + Dovecot-LDA. This is the error I get with every delivery -- dovecot: Oct 03 00:16:09 Info: auth(default): master in: USER 1 moya service=deliver dovecot: Oct 03 00:16:09 Info: auth(default): ldap(moya): user search: base=ou=users,dc=sld,dc=cu scope=subtree filter=(&(objectClass=posixAccount)(uid=moya)) fields=sldMailbox,uidNumber dovecot: Oct 03 00:16:09 Info: auth(default): master out: USER 1 moya home=/srv/vmail/m/moya/ uid=29174 gid=101 deliver(moya): Oct 03 00:16:09 Fatal: setuid(29174) failed: Operation not permitted -- 29174 is the uid for moya, is the same in /etc/passwd or in LDAP via posixAccount class. Any advise please? Regards, maykel

[Dovecot] new antispam plugin
by Johannes Berg 03 Oct '07

03 Oct '07

Sparked from the discussion on the list, I've put my antispam plugin into git and split up the code into a frontend and possibly multiple backends. See http://git.sipsolutions.net/dovecot-antispam.git/ (URL functions as both gitweb and git URL) Andreas, I took your README file and adjusted it, I hope you don't mind. I didn't fork from your git tree because you'd already implemented the libdspam backend there. Maybe you could take a look at the new backend/frontend separation and implement a libdspam backend. Aria, it should be possible to write a spamassassin plugin, quite easily if spamassassin supports training based on signatures, not quite so easily otherwise though I intend to plan this. Timothy, you could write the mysql logger as a backend too. I take patches :) Oh and as always thanks to Timo for implementing such a nice server and string, memory and mail handling API. johannes

[Dovecot] --enable-headers-install problem in 1.0.5
by Trever L. Adams 02 Oct '07

02 Oct '07

I am trying to get a SPEC file for an RPM to build a devel package. I have it working, except for one thing. 1.0.5 doesn't actually install the headers with that option to configure found in the subject. It does create the directory, but it doesn't put the files there. Timo, is this a known/unknown bug, or am I doing something stupid? Thanks, Trever

[Dovecot] SORT(DATE) and missing Date headers
by Kyle Wheeler 02 Oct '07

02 Oct '07

Hello, Occasionally, I get mail that's missing a Date header. The usual suspects are iTunes weekly mailings and NYTimes email-to-a-friend articles. I use qmail, which doesn't "fix" these malformed emails by adding a Date header (like Sendmail does), so when they get to my mailbox, they're just as badly formed as they were when they were sent, which is to say, they have no Date header. Unfortunately, this means that SORT (DATE) puts them at the beginning of the list---and in a mailbox with lots of old mail, that's usually the wrong spot. Now, my email clients will do some basic guesswork about when the message was sent, usually by falling back on the timestamp of the first-added Received header. So, they will display a date. But they have to then sort all messages themselves in order to get a valid sorting. Would it be possible to get Dovecot to fall back to Received header parsing whenever a message is missing a Date header? The idea is that SORT (DATE) would then become useful even in the face of commonly malformed email. How hard would this be to hack into the current Dovecot source? Does this maybe exist already (e.g. as SORT (X-DATE)? ~Kyle -- There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo. Please use in that order. -- Ed Howdershelt
