[Dovecot] NFSV4?
by Charles Marcus 16 Nov '06

16 Nov '06

Hi Timo, I just read about NFSv4 now being included in SuSE and Redhat Enterprise versions, and although I don't use it myself, wondered how this will impact Dovecot for those using it? Will it make life easier? Or is it even supported currently? Just curious... thanks... -- Best regards, Charles

[Dovecot] 1.0.rc13 released
by Timo Sirainen 15 Nov '06

15 Nov '06

http://dovecot.org/releases/dovecot-1.0.rc13.tar.gz http://dovecot.org/releases/dovecot-1.0.rc13.tar.gz.sig I'll just keep on making new releases now whenever something important is fixed. Hopefully there shouldn't be many left anymore. Most of the bugs fixed in this release were found by stress testing with my imaptest tool (http://dovecot.org/tools/imaptest.c) If you're interested in knowing how perfectly your Dovecot setup works (especially if you're using NFS), you could try the tool yourself also. I still see one crash with mmap_disable=yes, but it's pretty rare. Will see if I get it fixed before v1.0, but it's not that important. + deliver: If we're executing as a normal system user, get the HOME environment from passwd if it's not set. This makes it possible to run deliver from .forward. - Older compilers caused LDAP authentication to crash - Dying LDAP connections weren't handled exactly correctly in rc11, although it seemed to work usually - Fixed crashes and memory leaks with AUTHENTICATE command - Fixed crashes and leaks with IMAP/POP3 proxying - maildir: Changing a mailbox while another process was saving a message there at the same may have caused the changes to not be made into the maildir, which could have caused other problems later..

[Dovecot] 45second delays on log in
by Ben Marsh 14 Nov '06

14 Nov '06

Dear List Members, We have been running Dovecot as an IMAP server for web based access to email for our customers. At the moment, when the server is under load, some users are finding that it takes 45 seconds to log in. I was wondering if any of you guys would have any tips. I would love any information that would help solve or debug this issue. Background information: The server is Debian with kernel 2.4.31. We are running Dovecot 1.0rc6. I have reviewed the change logs and not found any changes pertinent to our situation from rc6 to rc14 (But maybe I am wrong). We have our own auth mechanism. This auth mechanism is the same used across our other products and we haven't had the same delays with the other products. From the information in the various log files the auth mechanism responds almost instantaneously but it still takes a long time for 1 OK Logged in. message to arrive on the screen when using telnet localhost 143 to login. All the mailboxes are stored over NFS. I have taken the step of moving the INDEXES from NFS to a local hard drive using default_mail_env = maildir:%h/mail:INDEX=/spare/%h in the config file. (/spare is a locally attached hard drive). We are using Maildir for our mailboxes so I am told that locking should not be a problem. A mailbox would never be accessed by two machines simultaneously due to the architecture of the system. In order to gain performance increases we also implemented an IMAP proxy between the webmail client and the imap server. This removes delays in all but the first attempt to access webmail. When logging into a user for which login has been verified to take about 45seconds deletion of the large numbers of messages seemed to speed up login for that particular mailbox indicating to me that it was other things that dovecot does after login and before the 1 OK Logged in. message is displayed that takes up all the time. Unfortunately this theory failed when I tried it with other users. I have also analysed the log files. of the 100,000 lines in the log file 49 were messages: Child 12040 (login) returned error 89 54 were messages: imap-login: Master sent reply with unknown tag 18 The actual number at the end of the message changes lots. The frequency of the extended logins would make it extremely unlikely that these messages are the problem. Any help is very much appreciated. Thanks, Ben Marsh

[Dovecot] Question regarding bounce messages on quota full.
by Mustafa A. Hashmi 14 Nov '06

14 Nov '06

Hi all, Using dovecot's LDA (debian backports package: 1.0rc2), users who have exceeded their quota when receiving messages see the message get bounced. This works fine for us, however, the sender is sent a message as follows: -- Start bounce text ERROR This is the Postfix program at host foo.domain.com I'm sorry to have to inform you that your message could not be be delivered to one or more recipients. It's attached below. For further assistance, please send mail to <postmaster> If you do so, please include this problem report. You can delete your own text from the attached returned message. The Postfix program <user(a)foo.domain.com>: Command died with status 11: "/usr/lib/dovecot/deliver" -- End bounce text Is it not possible to specify something a bit more civil for the sender? a "User is over quota" message works much better here. We're already running a script which notifies users when they approach a certain specified % that they're about to exceed quota, however, hoping they all comply is another thing entirely. Any assistance would be much appreciated. Regards, -- Mustafa A. Hashmi mahashmi(a)gmail.com mh(a)stderr.net

[Dovecot] NTLM authentication from Outlook
by Lars Skovgaard 14 Nov '06

14 Nov '06

Hi all I've enabled ntlm authentication in dovecot, and use dovecot sasl in postfix as well. Authentication with ntlm works well from Mac OS X Mail.app, as well as from Outlook Express, but fails with Outlook. Strangely enough, ntml authentication works in Outlook when using smtp (via postfix), but neither from imap or pop3 (both dovecot). As dovecot sasl handles all authentication against a mysql userdb, this strikes me as very strange. I've instructed my clients with Outlook to fetch mail using a ssl- encrypted connection, and to send using ntlm-authentication. This works, but I would like to have ntlm available as an option to all my clients, without forcing them to change mail-clients. I've turned on auth_verbose, auth_debug and auth_debug_passwords, and compared the passwordstring with the one calculated using dovecotpw, and they match. The only odd thing is that the username is returned from Outlook as an all-caps string, so user(a)domain.tld becomes USER(a)DOMAIN.TLD. I don't know if it matters, but I don't think so, as changing the user-login to an all-caps version doesn't solve the problem. Any hints will be most welcome. /Lars
