[Dovecot] 1.0.beta6 released
by Timo Sirainen 14 Apr '06

14 Apr '06

Fixes, mostly: * The login and master usernames were reversed when using master_user_separator (now the order is UW-IMAP compatible). * Killing dovecot master process now kills all IMAP and POP3 processes also. + -a parameter to dovecot prints now all settings that Dovecot uses. -n prints all settings that are different from defaults. + Added pop3_lock_session setting + %M modifier returns string's MD5 sum. Patch by Ben Winslow - PLAIN SASL authentication wasn't working properly, causing failed logins with some clients (broken in beta4) - Fixes to Maildir++ quota, should actually work now - Don't crash if passwd-file has entries without passwords (eg. deny=yes databases) - Fixed prefetch userdb to work nicely with other userdbs - If master process runs out of file descriptors, don't go to infinite loop (unlikely to have happened unless the OS's default fd limit was too low) - Fixed non-plaintext password lookups from LDAP. Patch by Lior Okman - %U modifier was actually lowercasing the string. Patch by Ben Winslow

[Dovecot] Re: unofficial Survey about your Dovecot server :) to compare with my own server setup...
by Roger Weeks 14 Apr '06

14 Apr '06

I've posted this to the Wiki as requested. Servers: 2 SuperMicro single-Xeon (dual-capable) 2.8, 1gb RAM, mirrored SATA boot Storage: 1 SuperMicro dual-Zeon 2.8, 2gb RAM, 600GB RAID5 SATA shared via NFS over GigE OS: RHEL 4 Users: 10,000 mostly POP users, SquirrelMail IMAP Auth: MySQL Maildir size: daily averages about 50gb Dovecot version: 1.0 beta 5 Client Software: squirrelmail, outlook, outlook express, thunderbird, eudora, Apple Mail, Claris Emailer, and other odd clients too numerous to mention This system is intentionally over-engineered, to replace the single server Courier-IMAP system that it replaced. Load on each Dovecot/ SquirrelMail server is very low and allows for a lot of growth. Our incoming MTA is Exim, on another pair of SuperMicro machines writing to the same NFS over GigE. -- Roger J.

[Dovecot] Feature request for pop3
by Adnae Mac Uthidir 14 Apr '06

14 Apr '06

Dear List, is it possible to integrate a function for timelimits the pop3-connects? I require this function for an email-masshosting-project. My problem is, the most customers will lookup all 30 seconds or 1 minutes for new mails, that is stupid so I mean. My idea is a function where the customer must wait (for example) 3 minutes for a pop3-connect and lookup for new emails. Is it possible? Thx for your help and for the very good software best regards, Sascha

[Dovecot] Compile issues dovecot-1.0.beta7
by Mark E. Mallett 14 Apr '06

14 Apr '06

Hi, I haven't tried compiling 1.0 series since -test52, figured I'd give it a shot. There were a couple of minor problems. This is building on a fairly ancient BSD/OS box, so the issues may not be universal, but I suspect these ones are. ==================== Building in src/lib-dict/dict.c : loading the 'dict' program fails because it can't find various RAND and other functions. Adding -lcrypto fixes. I did this by hand rather than adjusting the configure script; looks like the need for -lcrypto is detected in other cases, but not here. ==================== In src/plugins/quota/quota-fs.c , line 276: #ifdef HAVE_QUOTACTL if (quotactl(QCMD(Q_GETQUOTA, USRQUOTA), root->mount->device_path, root->uid, (void *)&dqblk) < 0) { I believe the first two arguments are backwards, i.e., should be: if (quotactl(root->mount->device_path, QCMD(Q_GETQUOTA, USRQUOTA), root->uid, (void *)&dqblk) < 0) { I have a vague recollection of seeing this already being reported, but can't instantly find it, so what the hey. ==================== Yours, -mm-

[Dovecot] 1.0.beta7
by Timo Sirainen 13 Apr '06

Sorry, the authentication problem still wasn't actually fixed in beta6. Now, this time I tested every possible authentication case that it really works. I'll soon create a CVS branch which is going to stabilize into the 1.0 release. I won't add new features there so it shouldn't really get broken anymore, at least because of new features.. So, two changes in this release: + Added shutdown_clients setting to control if existing imap/pop3 processes should be killed when master is. - Master login fixes, PLAIN authentication was still broken..

[Dovecot] problem with out-of-box fedora rpm
by Marc Newman 13 Apr '06

13 Apr '06

Hi Folks, Most of the available howtos suggest that an out of the box binary rpm should at least be able to start on a similarly out of the box Fedora Core 4 installation. However, whenever I run /sbin/service dovecot start I get a failed message. Dovecot was installed using the standard package that ships with FC4 (i386 0.99.14). The only slightly anomalous feature of my system is that wlan0 not eth0 is the primary network interface. This hasn't upset anything else though. I even tried disabling the firewall briefly to see if that had any effect, and it doesn't. So, two questions. Firstly, any ideas on why it might be failing to start? Secondly, where might I look (like, which logs/where) for clues? /var/log/messages doesn't contain any references to dovecot (I grepped it), so I'm out of ideas. My sendmail configuration is working perfectly, and I can send and receive emails fine. But I need pop3 access for some of my users. Just to recap, I haven't even got to the point of testing whether its listening, or configuring authentication. It will not start out of the box. Am I missing some essential configuration step? Marc.

[Dovecot] dspam plugin
by Ryan Kolak 13 Apr '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey everyone.. been struggling with building a mailserver and i'm almost done. One of the last pieces is integrating dovecot with dspam so that I'm users can train their spam filters easily (sieve filtering is the last piece left.. that should be interesting.. lol) Anyway, I think i found an issue with memory allocation, and I'm not sure if its due to changes to the code base or if its a 64 bit memory issue. When i try to move a message into or out of the spam folder, it fails, and with debugging on, there are strange entries in the syslog. Added a few more debugging statements, and I get the following showing up: Apr 11 00:04:41 uberserver imap: found signature 443b336a271581061887518 Apr 11 00:04:41 uberserver imap: working with signature (<E4>Z Apr 11 00:04:41 uberserver imap: in call dspam Apr 11 00:04:41 uberserver imap: /usr/bin/dspam --source=error --stdout - --class=spam --signature=(<E4>Z Apr 11 00:04:41 uberserver dspam[1361]: Unable to determine the destination user Apr 11 00:04:41 uberserver dspam[1361]: DSPAM agent misconfigured: aborting The line with the correct signature showing up is simply outputing 'signature' after: signature = mail_get_first_header(mail, SIGHEADERLINE); The 'working with signature' that shows the corrupted signature is right before call_dspam is called, and it outputs siglist->sig: ... syslog(LOG_INFO, "working with signature %s ", siglist->sig ); if ((*enh_error = call_dspam (siglist->sig, is_spam))) { ... This leads me to believe that there's a problem with: list_append(listpool, &siglist)->sig = p_strdup(listpool, signature); but I'm really not sure how dovecot deals with allocating pooled memory, as that's what it appears to be doing. I'm not sure what information might be useful to anyone in helping me look into this and the searches i've been able to do have been unsuccessful. Thanks in advance, Ryan - -- PGP Fingerprint - E15C CC7D 5830 AB8A C2AE 5C5E 80D8 6B63 D40B 015C -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFEOz9YgNhrY9QLAVwRAkK9AJ9Tf5eDFtNs2oYG6BpNxPNUUxZ3VwCfRhYo ify05xCWACczHUHvOBFyQYg= =en2A -----END PGP SIGNATURE-----

Migrated from Eudora/UW-IMAP in just few days without any major problem and now it is unning flawlessy since few months. One of the most appreciated pros is the use of maildirs, which are backup friendly. A new mail basically results in a single new small file, instead of a change in a big mailbox file, which helps a lot with differential/incremental backups.
