[Dovecot] UID sync errors
by Patrick MacDonald 26 Jun '06

26 Jun '06

Hello, I recently converted my 300+ email user system over to Dovecot. It is working fantastically, except for UID sync errors. I read everything I could find and only saw others with those problems in version 0.99 below. My log shows errors like this all day long for pretty much all users: dovecot: Jun 25 19:12:46 Error: POP3(nmichel): Maildir /home/rtb/users/nmichel/.Maildir sync: UID < next_uid (42 < 43, file = msg.oP8c:2,) dovecot: Jun 25 19:25:59 Error: IMAP(lcrowe): Maildir /home/dentist/users/lcrowe/.Maildir sync: UID inserted in the middle of mailbox (70 > 4, file = msg.AM81:2,) When this happens, IMAP and POP3 drop the connections sending errors to their clients. I use squirrelmail over IMAP and some new emails never appear until I delete the index files. I have tried deleting indexes, and the problem continued. I went from dovecot-1.0.beta3 to dovecot-1.0.beta9 and still happens. The only way it doesn't happen is when I append the INDEX=MEMORY trick as in: default_mail_env = maildir:~/.Maildir:INDEX=MEMORY but then it's all so slow for large mailboxes, it's painful. Here are some of my specs: Linux kernel 2.6.15 Maildir Auth from /etc/shadow Users from /etc/passwd Does anyone have any hints on where I should start? Thanks in advance. I love Dovecot. I really hope I can get this resolved. Patrick MacDonald admin(a)athensguy.com

[Dovecot] OE pop3 > imap subfolder migration?
by Sysadmin 26 Jun '06

26 Jun '06

Hello. This isn't actually a dovecot question, but I'm running in clienys servers dovecot mostly as pop3 server and now started to migrate some servers to imap. But as clients uses Outlook Express how to transfer their pop3 settings and mailboxes to imap?. Making a new mail account for imap is easy, and drag & drop the default folders (inbox, outbox etc) messages to imap accounts default folders is easy, but what about subfolders? Some users have hundreds subfolders and creating them & transfering messages by hand is a pain. So have anyone a better and faster solution how to migrate Outlook Express pop3 account to the imap account, preserving the same folders, rules etc. -- Sysadmin

[Dovecot] RHEL 3 and quota issues.
by Alan Premselaar 26 Jun '06

26 Jun '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Thanks to code provided by Geo Carncross, I was able to determine what the problem was with v2 quota support on RHEL 3 using ext3 filesystems. I've included a patch file for quota-fs.c <sys/quota.h> on RHEL 3 sets _LINUX_QUOTA_VERSION to 1 if it's not defined by default. I copied <sys/quota.h> to ./sysquota.h and edited it to set _LINUX_QUOTA_VERSION to 2 if not defined since that's the version i'm using on my machine. I don't know if that's necessarily appropriate so I'm not including that file. (I then modified quota-fs.h to load "sysquota.h" instead of <sys/quota.h>) I was able to get it to compile and properly show the quota information now. I'd like to do more testing (like seeing if explicitly setting _LINUX_QUOTA_VERSION to 2 is really necesssary) but my one and only RHEL 3 machine is my production mail server, so I can't really do that. Anyways, since I figured out the problem and fixed it for myself, I thought I would share :) Timo, perhaps if you have the time to look at the patch and if the modifications to the quota.h file are necessary or not and include it into the next CVS update, I'm sure people would appreciate it.

[Dovecot] escaping in sqlite
by Jakob Hirsch 26 Jun '06

26 Jun '06

Hi Timo&all, a recent change in the sql drivers introduced escaping, but sqlite is a different in this aspect: You cannot escape with a backslash, the only character that needs escaping is the quoting character itself (by doubling it, as the SQL standard says). As the escaping function does not know which quote character is used, one should only use the single tick ' (again, as the SQL standard says) and the escaping function double any single quote in the string. (untested) patch for the latter attached.

[Dovecot] recent dovecot: assertion failed.
by sergey ivanov 25 Jun '06

25 Jun '06

Hi, today I have built dovecot from cvs sources, and upgraded server from beta-7 to this newer version. Then i got problems with opening INBOX using thunderbird 1.5.0.2. The client says "Opening folder...", then, after about half a minute, blinking "connecting to the server" and returning to "Opening folder..." /var/log/maillog gets the messages: --- Jun 22 17:19:07 parkheights dovecot: imap-login: Login: user=<seriv>, method=plain, rip=66.80.117.2, lip=192.168.10.14, TLS Jun 22 17:19:26 parkheights dovecot: IMAP(seriv): file index-search.c: line 845 (search_get_seqset): assertion failed: (ctx->seq1 <= ctx->seq2) Jun 22 17:19:26 parkheights dovecot: child 25812 (imap) killed with signal 6 --- and this lines repeat and repeat. At the same time I can open some INBOX' subfolders at the same server. So, I think it is a problem not with a server's software, but with mail storage. Help me, please, - how can I fix these indexes, or what causes the problem with access to that mail folder?

Timo - The only behavior change that I notice is that when I exit the telnet session the truss also exits. Previously, the truss hung around until I did the "pkill dovecot", after exiting the telnet session. So, that's weird. But, hold on!

[Dovecot] dovecot-1.0_beta9 : (auth) killed with signal 11

I have just upgraded from courier to dovecot and things seem to be working okay (after a few problems getting shared folders working correctly). I notice the following error message in my logs:- Jun 23 11:17:32 calzone dovecot: child 1258 (auth) killed with signal 11 I am using the beta9 ebuild that is available from gentoo portage. I have followed the steps to try to get a core dump but it doesn't seem to be working.

[Dovecot] LMTP revisited
by Glenn Leavell 24 Jun '06

24 Jun '06

During the early Dovecot LDA brainstorming discussions, there was some talk about the possibility of including an LMTP interface, and I've noticed that there's an "is it needed?" question about LMTP in Dovecot's TODO file. I'd like to put in a vote for LMTP, and I'm wondering if anyone else has a need for it. Specifically, I'd love an LMTP-enabled LDA that uses hard links when when delivering the same message to multiple recipients (I'm thinking Maildir files), as it would be a nice way to facilitate so-called Single Instance Storage.
