[Dovecot] Mailing lists in Dovecot?
by Peter Reinhold 01 Nov '10

01 Nov '10

Hi all, I was wondering if anyone could recommend a simple mailing list manager that plays well with a Postfix/Dovecot setup, with virtual domains? It really just has to be very simple, basically, an alias would work, if I could rewrite the sender address/name, and I don't really need the possibility for users to subscribe via e-mail based commands. I've looked at the XEXEC plugin as a possible method of doing this, via some Perl perhaps, anyone has any experience using this they would like to share? Mvh, Peter Reinhold / peter(a)reinhold.dk

[Dovecot] auth child abort - "Requested NTLM scheme, but we have only SSHA256"
by LEVAI Daniel 01 Nov '10

01 Nov '10

Hi! I noticed these messages in my logs. It seems that the user checked the "encrypted password" in her outlook or something, and wants NTLM auth. I'm storing all the passwords as SSHA256, and when the user tries to auth, this happens: => dovecot.info auth: Info: password(<username>,<user_ip>): Requested NTLM scheme, but we have only SSHA256 auth: Debug: sql(<username>,<user_ip>): query: SELECT username AS user, password, home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid, userdb_import AS userdb_userdb_import FROM userdb WHERE auth_username = '<username>' AND login = 'enabled' => dovecot.log auth: Error: sql(<username>,<user_ip>): Multiple password values not supported auth: Panic: file passdb-sql.c: line 113 (sql_query_callback): assertion failed: (password == NULL || scheme != NULL) master: Error: service(auth): child 10679 killed with signal 6 (core not dumped - set service auth { drop_priv_before_exec=yes }) Is this an error condition if I store the password in a different scheme than what user is requesting?

[Dovecot] Testing pop3/imap4 and mdbox corrupted indexes?
by Odhiambo Washington 01 Nov '10

01 Nov '10

I have two questions: 1. What method/tool (other than a MuA) can I use to test my Dovecot setup from Windows CLI when ssl is enabled? I have tried connecting to to the pop3/imap4 services from a Windows PC but here is what I get: [pop3] +OK Dovecot-2.0-sis ready. user wash(a)domain.co.ke -ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections. [imap4] OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED AUTH=DIGEST-MD5] Dovecot-2.0-sis ready. login wash(a)domain.co.ke S3ecreat BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but your client did it anyway. If anyone was listening, the password was exposed. NO [PRIVACYREQUIRED] Plaintext authentication disallowed on non-secure (SSL/TLS) connections. 2. When mdbox indexes are corrupted, are they automatically repaired/rebuilt or must I specify this in the configuration? How long does it take? Nov 01 12:08:04 pop3(wash(a)domain.co.ke): Error: Corrupted dbox file /var/spool/virtual/domain.co.ke/wash/mdbox/storage/m.1 (around offset=1941): Ex t refs metadata corrupted: 3861 783856 75/80/75805ed445f1b8b31508dba8d86280a37a74aec1-fabfb11f9f80654ced090000dcbe1dcb Nov 01 12:08:04 pop3(wash(a)domain.co.ke): Error: Corrupted dbox file /var/spool/virtual/domain.co.ke/wash/mdbox/storage/m.1 (around offset=1941): ui d=5 points to broken data at offset=1911 Nov 01 12:08:04 pop3(wash(a)domain.co.ke): Warning: mdbox /var/spool/virtual/ domain.co.ke/wash/mdbox/storage: rebuilding indexes When I connect using outlook, I see this on Outlook: Task 'wash(a)domain.co.ke - Receiving' reported error (0x800CCC90) : 'Your incoming (POP3) e-mail server has reported an internal error.

[Dovecot] [OT] dovecot appliance
by Johan Hendriks 29 Oct '10

29 Oct '10

Hello all. I am reading the mailinglist for a long time now, and there was a thread i believe called webgui or something. In this thread there was a company i believe german, that was working on a dovecot appliance with a web based gui to administrate a dovecot mail server. The problem is i did not save the URL of that company. Does anyone know which company make the appliance. Or does anyone knows a good webbased tool for dovecot. The reason is that in a windows environment, with only a few FreeBSD machine's , my collega's get frustrated if they can not use a mouse. They even want a mouse on there smartphone's :D I am doing the administration of the mail server, but when i am not there, it would be nice if they can do things them selves. thanks for your time. regards, Johan Hendriks

ALL other mail delivers perfectly but I dont know whats with crontab on this mail server. Thanks Jerrale G. SC Senior Admin

[Dovecot] Upgrading from 1.2.8 to 2.0.6: INBOX not selectable in Thubderbird (greyed and italic)
by Michele Bergonzoni 29 Oct '10

29 Oct '10

I recently upgraded from 1.2.8 to 2.0.6, I am using Maildir, and Thunderbird is showing the INBOX grayed out and in italics, and does not show new messages in it (it shows messages previously downloaded). This occurs when Thunderbird is restarted (if I upgrade dovecot, TB keeps working fine until I shut it down, and at next startup it greys out the inbox). All the subfolders of INBOX work fine. Accessing with horde+imp webmail works fine. I'm using TB 3.1.6 After some traffic capturing, The first difference I see in the IMAP exchange is the answer to 6 list "" "INBOX" Which for 1.2.8 is: LIST (\HasChildren) "." "INBOX" and for 2.0.6 is: LIST (\Noselect \HasChildren) "." "INBOX" Of course for the same user and same maildir. I enabled tb-extra-mailbox-sep in 2.0, but it doesn't appear to differ (I don't really think it should). Any help will be very much appreciated. My 1.2.8 config for the namespaces is: namespace private { prefix = INBOX. inbox = yes location = maildir:~/Maildir } namespace public { prefix = shared. location = maildir:/usr/local/shared list = yes subscriptions = no } And the config for 2.0.6 is the same with new syntax: namespace { type = private prefix = INBOX. inbox = yes location = maildir:~/Maildir } namespace { type = public prefix = shared. location = maildir:/usr/local/shared list = yes subscriptions = no } Regards, Michele Bergonzoni

[Dovecot] Can you POP a specific folder in Dovecot?
by Peter Reinhold 29 Oct '10

29 Oct '10

Hi all, I am in the middle of migrating from an old, Windows based mailserver, and have run into a small challenge I hope someone here can help me with. In my old setup, a user could have folders on the server, and by using his login with the mailbox appended, could pop a given folder specifically. For instance, logging in with user(a)example.com would pop INBOX, and logging in with user-folder(a)example.com would pop just that specific folder. Is it possible to do something like this in Dovecot, or is the only possible way of popping folders by using the virtual plugin?
