[Dovecot] Dovecot crashes on certain spam messages
by Karl Eklund 05 Feb '04

Dovecot crashes. I think it's because of some message in my spam folder. It has happened once before, and that time I solved it by deleting that folder. It happens when I start gnus ("Checking messages in folder spam" or something like that), which makes gnus just stop, or when I try to enter that folder in mutt. Jan 30 17:07:09 kalle imap(ke): file imap-bodystructure.c: line 278 (part_parse_headers): assertion failed: (part->physical_pos >= input->v_offset - start_offset) Is there something I can do to determine which message it crashed on? Maildir format, version 0.99.10.4.

[Dovecot] dovecot crash on sendfilev64 on solaris 8 (32bit) (WORKAROUND)
by Fabio Pietrosanti (naif) 04 Feb '04

Hi, related to my previous email i found that setting "mail_save_crlf = no" instead of yes make dovecot working. However if enabled on solaris 8 it doesn't work hanging on sendfilev64() call. I noticed that maildir file names are still different from maildrop and dovecot but now works. However moving bigger mailbox from local storage to remote imap server i receive "Disconnect for inactivity while waiting for command data" error triggered by client_input_timeout function in imap/client.c . The timeout is defined as CLIENT_CMDINPUT_TIMEOUT which is defined as CLIENT_OUTPUT_TIMEOUT which is 1 minute (60*1000) . I think that could be usefull to have this timeout tunable because when you tranfer into the imap server large quantity of data if it takes more than 1 minutes, process goes timeout ( altought with mutt 1.4i client ) . Regards -naif

Hi, i'm running dovecot on a SMP sparc 32bit server with solaris 8(latest patch installed). Dovecot with ssl. Postfix+imap+maildrop . Dovecot work fine with every email and folders delivered by maildrop, but now i'm trying to move all my local folders (i'm using mutt and i'm storing my emails locally on my pc) to the imap server . The upload of an entire 12000 mails folders worked fine, when i try to access that folder i can see "fetching headers" and all it's ok but when i attempt to read a message dovecot imap process crash. Dovecot crash even if i attempt to read one single email moved from my local inbox to remote imap INBOX maildir. Dovecot work fine on every folder created by maildrop. I made some debugging with truss and found that he die on sendfilev64 call: 5113: 0 7 O K S t a t u s c o m p l e t e d .\r\n 5113: poll(0x0008B450, 1, 204) = 0 5113: poll(0x0008B450, 1, 0) = 0 5113: poll(0x0008B450, 1, 999) = 1 5113: time() = 1075892017 5113: read(0, 0x000925AC, 3796) = 35 5113: a 0 0 0 8 U I D F E T C H 1 2 5 1 3 B O D Y .

Hi, Dovecot (pre-compiled version of Fedora Core 1, configured for Maildir) is running fine for me since a few days. It happened now twice to me that dovecot died with the following error message in /var/log/maillog: Feb 4 11:18:27 hundehuette imap-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded Feb 4 11:18:27 hundehuette dovecot: Login process died too early - shutting down As these previous log messages indicate the login was working before without any problem: Feb 4 11:02:37 hundehuette imap-login: Login: andrea [192.168.2.138] Feb 4 11:05:56 hundehuette last message repeated 30 times Feb 4 11:09:02 hundehuette last message repeated 15 times Feb 4 11:12:08 hundehuette last message repeated 15 times Feb 4 11:15:15 hundehuette last message repeated 15 times Feb 4 11:18:21 hundehuette last message repeated 15 times Feb 4 11:18:26 hundehuette last message repeated 12 times Dovecot is running as user "dovecot" who does not have a ~/.rnd file Any idea?

I'm also seeing this - I wasn't able to get a core dump, but was able to get info from strace/lsof to track down the message: strace shows in a continuous read loop, as it's trying to go past EOF. pread(9, "", 3502, 30524) = 0 pread(9, "", 3502, 30524) = 0 pread(9, "", 3502, 30524) = 0 I've attached the problem message (gzipped). -D -- <dr.pox> does whistling in the dark make me go blind faster?

A regular FAQ on the SA-Talk list is how to integrate SA into someone's IMAP/POP3 server, and once Dovecot gets popular, you'll start seeing that question here. I run SA from sendmail via MIMEDefang (to reject the egregious stuff), and from procmail on delivery (to tag and quarantine the borderline stuff). I'm not sure why people would use it in the IMAP server, but the question does come up.

Trying to crank it up on our RedHat 8.0 system... I get the following.. I am sure it is something simple in the config.. just don't know what... Any help would be greatly appreciated.. Here is from the log.. If there is a way to get more log info that might help he as well..

[Dovecot] Migrating from UW: mbx detection and conversion
by Kenneth Porter 30 Jan '04

30 Jan '04

I want to migrate my big mail folder hierarchy in preparation for converting from UW-IMAP to Dovecot. I've got a bunch of mbx format folders but some remain mbox. Has anyone done this? Any scripts out there for automating the conversion to all-mbox? I believe the only format conversion available is mailutil (part of UW-IMAP) and it works by opening an IMAP connection to the server and moving messages from one folder to the other. Is there any simpler method?
