[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

[Dovecot] Slight problem with dovecot + IMAP
by Timothy Murphy 02 Oct '07

02 Oct '07

I'm running dovecot on my desktop with kmail as IMAP client on my laptop. When I start kmail on the laptop it sometimes takes several minutes to "calm down". The number of messages listed in the IMAP inbox increases greatly - maybe from 2500 to 3000 - and then slowly decreases. There are sometimes a large number of duplicate messages, which kmail allows one to delete. I don't know if this is a kmail or dovecot problem. It is quite likely there is something wrong in my setup. Any suggestions or advice gratefully received.

[Dovecot] IMAP Fetch fails with BAD instead of NO
by Reinier Bezuidenhout 02 Oct '07

02 Oct '07

Hi, I'm running version 1.0.3 of dovecot using IMAP and using javamail to access the mail. The application I'm using (when stress testing the system by doing simultaious creation of email and deleting emails, it sometimes get into the state where the application (via javamail) ask for the UID of a message that has been expunged and deleted (no longer exists). Dovecot returns with the following error: AXXX FETCH 14 (UID) AXXX BAD Error in IMAP command FETCH: Invalid messageset This can easily be reproduced by using telnet to 143 and giving the command by hand. When I read through the source code, there were obvious comments that states the dovecot will not return NO on fetch errors, only BAD. So I assume it is done on purpose. My question is that in RFC 3501 for fetch it says: (section 6.4.5) Result: OK - fetch completed NO - fetch error: can't fetch that data BAD - command unknown or arguments invalid No I guess a UID that is out of range could be considered "arguments invalid", but shouldn't it be a soft error with NO as a result where "can't fetch that data" is more appropriate according the the RFC. The command isn't syntactically BAD, the requested data just does not exists. The same command tested against another IMAP server returns AXXX NO message not available Not that they are necessarily correct, but it just begs the question.

Re: [Dovecot] Moving email from a folder to another using IMAP isvery slow (sometimes)
by Stefano Scalise 02 Oct '07

02 Oct '07

Hi to all, very strange! I tried to debug why imap process takes 100% CPu and it is very slow when I move an email from an imap folder to another imap folder and then I typed: strace -tt -o /log-imap.txt -p <process number> well, during the trace the imap process doesn't crash and it is very fast. If I stop the tracing, I have again the problem and sometimes the crash of the process. Any help?

[Dovecot] plugin problem
by Lars Stavholm 02 Oct '07

02 Oct '07

I'm trying to do a rewrite of the dspam_plugin for dovecot 1.1b1. There are some API changes that warranted an update of the plugin. Also, I wanted the dspam_plugin to be able to handle pristine mails for dspam retraining, as opposed to the signature based retraining. Question: How can I retrieve the full unix path for a specific mail? The original code uses mail_get_first_header() to retrieve the signature header. I need something like mail_get_mail_file_path(&path) which I then could pass on to dspam. Is there some such function available? Thanks in advance /Lars
