[Dovecot] Plaintext Authentication from Localhost
by Paul C. Bryan 06 Sep '04

06 Sep '04

Hi: It appears that at least at one time, Dovecot supported plaintext authentication from localhost, even if disable_plaintext_auth = yes. To wit, the example configuration file reads: # Disable LOGIN command and all other plaintext authentications unless # SSL/TLS is used (LOGINDISABLED capability). Note that 127.*.*.* and # IPv6 ::1 addresses are considered secure, this setting has no effect if # you connect from those addresses. #disable_plaintext_auth = yes On brief inspection of the code, there doesn't seem to be any such support. This is corroborated by the fact that 0.99.10 (Debian package) behaves by disallowing plaintext authentication via connections on localhost. This is a particularly useful feature, as local webmail clients can safely authenticate via the local interface without requiring secure authentication. So, the question is, is Dovecot supposed to support plaintext auth via localhost even if disallowed in dovecot.conf? If so, any suggestions as to what I may be doing wrong? Yours truly, Paul C.

[Dovecot] Rogue child imap processes when using Mac imap clients
by darren david 31 Mar '04

31 Mar '04

hi all- I am currently running dovecot 0.99.10p2 on OpenBSD-3.4-snapshot. It has been very stable, but I have recently noticed that I am having problems when checking IMAP-SSL mail with Mac OS X clients. There are not problems using Mozilla or Outlook on Windows, but Mac clients (Thunderbird, Mozilla, Mail.app) all exhibit the same behavior - they can check and send mail, but I end up with a single, rogue child imap process on the server that pins the cpu that i have to 'kill -9' to clear out. Is this a Mac problem or a Dovecot problem? I'm not even sure what to look for in the logs... Thanks, Darren David

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

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.

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.

[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?

[Dovecot] Dovecot not creating dirs
by marko sarunac 30 Jan '04

30 Jan '04

I have looked trough the archives and found similar scenarios but mine is a bit diff I got dovecot running (0.99.10.4-2) on debian testing and what is happening is that i created /home/marko/mail directory and configured my postfix to deliver mail to ~/mail/Inbox my default mail env is default_mail_env = mbox:%h/mail/:INBOX=%h/mail/Inbox:INDEX=%h/mail/.indexes Now when i first started my mozilla imap client what happened was! Jan 26 21:46:34 imap(marko): Can't create temp index /home/marko/mail/.indexes/.imap/INBOX/.temp.limbic.7523: No such file or directory Jan 26 21:46:34 imap(marko): utime() failed with index file /home/marko/mail/.indexes/.imap/INBOX/.imap.index: No such file or directory after i manually :~/mail$ mkdir .indexes :~/mail$ cd .indexes/ :~/mail/.indexes$ mkdir .imap :~/mail/.indexes$ cd .imap/ :~/mail/.indexes/.imap$ mkdir INBOX :~/mail/.indexes/.imap$ cd INBOX/ :~/mail/.indexes/.imap/INBOX$ i only get Jan 26 22:06:34 limbic imap(marko): utime() failed with index file /home/marko/mail/.indexes/.imap/INBOX/.imap.index: No such file or directory On the other note...when i try to delete any mail from Inbox using IMAP client i get "The current command did not succeed. The mail server responded: [TRYCREATE] Mailbox doesn't exist: trash" This obviously shows that dovecot can't create neither files nor directories I am using non system wide readable directories and just to try things i did chmod -R 777 mail from /home/marko didn't help any ideas and comments are greatelly appreciated!!!
