[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

[Dovecot] Maildir
by Walt Shekrota 01 Apr '11

01 Apr '11

I noticed in Cyrus they seem to address maildir++ recognised by IMAP. I need to know does Dovecot recognise this format? Procmail has an ability to deliver mails to different folders which if unrecognised renders the whole process useless. Does Dovecot have a similar deliver method? Thanks. -Walt
