[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] The Status: header is forced
by Olivier Tharan 21 Jun '04

21 Jun '04

Hi, I started testing dovecot for our next POP/IMAP server (nearing production state), and noticed that the Status: header is always added, with a value of 'O' or 'RO'. This happens in `lib-index/mbox/mbox-rewrite.c'. This does not seem to happen in the Maildir case. Is the Status: header really needed in every case? This breaks mutt which displays mails with a 'O' flag instead of 'N'. My dovecot is 0.99.10.4 (FreeBSD port), but the behavior is still the same in the CVS version. -- olive

[Dovecot] imap indexing error when moving multiple mails
by Hauke Fath 06 May '04

06 May '04

Hi, I've got an 'interesting' problem with a dovecot 0.99.10.4 setup on NetBSD/i386 1.6ZK. dovecot is serving imap only at the moment, using mbox format mailboxes. '/etc/dovecot.conf' is pretty vanilla - among the modified settings, mail_read_mmaped = yes maildir_check_content_changes = yes mbox_lock = fcntl could be relevant. Anyway - from time to time when I move a bunch of mails ( < 1) from a mailbox to another (or to the trash), the client (I've seen it with Eudora 6 on a Mac, with Mozilla 1.6 and Sylpheed on NetBSD) reports an "internal error" and the maillog shows Mar 25 14:07:33 bounce imap-login: Login: hf [130.83.xxx.yyy] Mar 25 14:07:44 bounce imap(hf): Error indexing mbox file /home/hf/Mail/Leute/Marc Wirth: LF not found where expected Mar 25 14:09:30 bounce imap(hf): Error indexing mbox file /home/hf/Mail/Leute/Marc Wirth: LF not found where expected which, if I retry the operation to another time, does not persist and is not strictly repeatable. I've set the number of allowed concurrent connections to '1' on the client, but that doesn't help. Is there anything obvious that I overlooked, or have I tripped over a genuine bug? hauke -- Hauke Fath /~\ The ASCII Ribbon Campaign Institut für Nachrichtentechnik \ / No HTML/RTF in email TU Darmstadt X No Word docs in email Ruf +49-6151-16-3281, Fax -3778 / \ Respect for open standards

[Dovecot] shared folders?
by Gareth J. Greenaway 26 Apr '04

26 Apr '04

Greetings, I saw mention in results from a google search that there was some support in dovecot CVS for shared folders, is there some docs on how to use them? Provided there is in fact support for them in CVS. Thanks. -- Gareth J. Greenaway | gareth(a)wiked.org SCLUG - Simi Conejo Linux Users Group http://www.sclug.org

RE: [Dovecot] triggering multiple actions on pop-3 request

How about just running fetchmail in daemon mode, so it's polling for messages instead of running on demand? Then you don't need to worry about any special integration issues. Julian.

[Dovecot] Calling gentoo maintainers
by Zach Bagnall 13 Apr '04

13 Apr '04

If anyone knows someone with CVS access can they please take another look at http://bugs.gentoo.org/show_bug.cgi?id=22080. It has been in bugzilla for nearly nine months. Would like to see this in portage - masked is fine - so at least everyone is working off the same file. Cheers Zach.

[Dovecot] blank line at the top of mbox
by KB Digital 10 Apr '04

10 Apr '04

Hello, It seems dovecop pop3 server sometimes inserts a blank line at the top of the mbox. It only happens for certain users not all. I'm not sure why it's doing that. Looking back into the mailing list, I saw the same post in Oct 6, 2003 but there was no reply to it. Is there a patch or fix that i can use to get around the blank line? Thank you. Ken

I tried putting a .rnd file in /var/libexec/dovecot, no help. - Fedora Core 1.0 - dovecot-0.99.10-6 - openssl-0.9.7a-23 - About 20 users, using pop, pops, imap, imaps. I had to run a cron job that checks every minute to see if dovecot is running, and restart it if it isn't. I'd love to get this figured out, though. I see another message about this in the list archives, at the end of January. I'll post if I find anything... Rob

[Dovecot] Dovecot startup at boottime fails
by Bavo De Ridder 08 Apr '04

08 Apr '04

Hi, I am running dovecot 0.99.10.4 on SuSE 9. I installed it using apt-get from the gwdg repository. The dovecot service is configured to start at boottime in run level 3 and 5. However, it dies immediately with this error (/var/log/mail.err): dovecot: Login process died too early - shutting down Starting the service afterwords from a prompt as root with the command: /etc/init.d/dovecot start works without a glitch. Attached you can find my dovecot.conf and the startup script /etc/init.d/dovecot. I hope someone could shed some light on this issue.

[Dovecot] dovecot not reconnecting to ldap after ldap restart
by Jared 05 Apr '04

05 Apr '04

I upgraded dovecot two weeks ago from 0.99.10-0.rc2 to 0.99.10.4-1woody1 (both from the woody backport packages from braincells.com) Dovecot is using LDAP on a separate machine for authentication. (through stunnel if it matters) At 4:00 am, the LDAP server stops, dumps the ldap database, and then starts back up. Because the LDAP server is stopped, anyone who tries to authenticate during the few seconds will be denied. This isn't a big deal since it's 4:00 am. However, twice in the past two weeks, it appears that if dovecot can't connect to the LDAP server, it loses the ability until dovecot is restarted. It's only happened since I upgraded, and it's only happened twice, presumably when someone was trying to check their mail at the precise moment the LDAP server is down. I get the following entry in mail.err: Mar 30 04:00:18 akbar dovecot-auth: LDAP: ldap_result() failed: Can't contact LDAP server Mar 30 04:00:19 akbar dovecot-auth: LDAP: Can't connect to server: localhost Mar 30 04:00:50 akbar last message repeated 36 times . . . The two times it has happened, ldap is responding properly (all other services we provide which use LDAP still work), stunnel on the dovecot machine is still running, and dovecot is still running, accepting IMAP and POP connections, but failing at the authentication phase. Is there some change or bug in dovecot which would make this happen? Or is there a problem with my set up? Thanks in advance for any ideas. -jared
