[Dovecot] SiS: Attachment file larger than expected
by Andrew Lewis 04 Apr '11

04 Apr '11

I recently set up SiS and imported a large chunk of mail. I've noticed one or two instances of this in the logs: Mar 28 09:03:50 mail dovecot: imap(xxx(a)yyy.zz): Error: Attachment file /mailstore/attachments/ce/73/ce737a45fe07495e2ae6466f9e381a30d5ec300406f11269d79bd5608cc0c922-822b3d2df67f8e4d7f5000009501e12a larger than expected (252218) Mar 28 14:52:34 mail dovecot: pop3(zzz(a)xxx.yy): Error: Attachment file /mailstore/attachments/c5/e1/c5e13d671d1d796680ae7166363afcb819af3d9cd04e01de7d65031b2f732bdf-b2ecf918b910904d826200009501e12a larger than expected (143959) Could that be an indication of a hash collision?

[Dovecot] doveadm mailbox status - getting the size in bytes
by Patrick McLean 04 Apr '11

04 Apr '11

Hi, doveadm has an option to get the "vsize" of mailboxes, which is calculated by counting the number of linefeeds, but there does not appear to be way to simply get the size in bytes of a mailbox. I was wondering if there is something I am missing (I am using mdbox), or if not is it possible to implement this. Thanks

[Dovecot] dovecot ldap failed to recover
by Jan-Frode Myklebust 04 Apr '11

04 Apr '11

One of our backend pop/imap-server running dovecot v1.2.16 experienced some problems yesterday. It suddenly couldn't authenticate users anymore, flooding the logs with: pop3-login: Disconnected (auth failed, 1 attempts): user=<user1(a)example.com>, method=PLAIN, rip=192.168.42.15, lip=192.168.42.28 The problem seemed to start with this log entry: Mar 29 18:57:21 popimap1 dovecot: auth(default): ldap(userX(a)example.com,192.168.42.15): Connection appears to be hanging, reconnecting and this suspicious entry a few seconds later: Mar 29 18:57:41 popimap1 dovecot: auth(default): LDAP: Reply with unknown msgid 2 Afterward 18:57:21 it was unable to authenticate any users before I restarted the dovecot service. Also some of our postfix servers reported ldap lookup failures between 18:56-18:58, but then recovered. Looking at the ldap server side, we saw no problems logged, but netstat reports there being 3 active ldap sessions towards the dovecot server that failed yesterday, while the dovecot server only has 1: ldap1$ netstat -na |grep 192.168.42.28 tcp 0 0 192.168.43.2:389 192.168.42.28:44408 ESTABLISHED tcp 0 0 192.168.43.2:389 192.168.42.28:36464 ESTABLISHED tcp 0 0 192.168.43.2:389 192.168.42.28:60580 ESTABLISHED popimap1$ netstat -na| grep 192.168.43.2 tcp 0 0 192.168.42.28:60580 192.168.43.2:389 ESTABLISHED So it looks to us like there was some problem with either the network, or the ldap-server for a short periode, and that dovecot then wasn't able to recover from this. -jf

[Dovecot] install question
by Gerard Ranke 04 Apr '11

04 Apr '11

Dear list, I'm trying to build a dovecot-2.0.11 package for our systems, and so I would like to install it to a temporary directory. But when I use "gmake DESTDIR=/tmp/build install", instead of binaries, it's wrapper scripts that get installed for dovecot, doveconf and doveadm. When I install to the default location all is well. Does anybody know how how to install to a temp location? Thanks in advance for your answer! Best regards, Gerard Ranke

[Dovecot] Segmentation fault with vpopmail auth
by Samuel Montosa 04 Apr '11

04 Apr '11

Hi. I am new in the list. First, excuse my english. I am not native speaker. A few hours ago I had a problem with process dovecot-auth and vpopmail. Versions I had using, working, were: vpopmail 5.4.28 dovecot-1.1.12 I tried to compile dovecot-1.2.16. Compilation was well but in execution system said: kernel: dovecot-auth[2842]: segfault at 645f20 ip 0000000000645f20 sp 00007fff69bd3708 error 15 in dovecot-auth[645000+1000] and so. Then, I tried to recompile dovecot-1.1.12 (original version I had working) but system said the same. After investigation, I saw I had mixed of vpopmail versions. Problem was I had /home/vpopmail/lib/libvpopmail.so in my system. When this file is present, compilation of dovecot link dovocot-auth to dynamic library libvpopmail.so, but it is not necessary since I had my system working using vpopmail without this .so. What I recommend is to compile a fresh vpopmail. Now I am using vpopmail-5.4.32 (at now, stable version) and dovecot-1.2.16. First, compile vpopmail and make sure you purge /home/vpopmail/lib/ of libvpopmail.so. Fresh installations of vpopmail, from tar.gz (not from SVN) _doesn't_ build libvpopmail.so, so make sure this file doesn't exist before you compile dovecot. For me, library dependencies are: mymachine:/usr/local/src/dovecot-1.2.16# ldd src/auth/dovecot-auth linux-vdso.so.1 => (0x00007fff63df5000) libpam.so.0 => /lib/libpam.so.0 (0x00007f9f925e1000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x00007f9f923aa000) libdl.so.2 => /lib/libdl.so.2 (0x00007f9f921a5000) librt.so.1 => /lib/librt.so.1 (0x00007f9f91f9d000) libc.so.6 => /lib/libc.so.6 (0x00007f9f91c3c000) /lib64/ld-linux-x86-64.so.2 (0x00007f9f927f7000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f9f91a1f000) I hope this helps. It was a strange "bug". Regards. -- Samuel Montosa
