[Dovecot] corrupt attachments
by Brian Thompson 02 Dec '05

02 Dec '05

Not sure if this has already been covered, but any pointers or suggestions would be greatly appreciated. We just realized last night that dovecot-stable seems to be corrupting the attachments within users' inboxes. In an attempt to resolve the problem, we upgraded the mail server here to Dovecot 1.0alpha4 but it didn't help. To the best of our knowledge we didn't start experiencing this phenomena until we migrated from Solaris 8/Sparc to Solaris 10/x86 about 3 weeks ago. To be more specific: A non-corrupt attachment can be sitting within a user's mail spool (mbox format) and live there without a problem until an imap client goes to download the attachment via dovecot. At that time, dovecot seems to be stripping the last four characters from each base64 encoded ascii line within the attachment and rewriting the message within the mail spool without those characters. From then on, the attachment is permanently corrupt, even via local unix direct file access clients such as pine or elm. We've temporarily switched back to UW imapd, but users have noticed the decrease in speed - not having the indexing available. Again, any suggestions would be greatly appreciated. Thanks, Brian

[Dovecot] Multiple authentication databases and storage locations
by Odhiambo Washington 02 Dec '05

02 Dec '05

Hello Everyone, I am playing with the $subject matter using 1.0alpha4, and thanks to the archives, I lifted this one from Alexander Shikoff off and used it in my setup. auth default { mechanisms = plain user = root passdb pam { args = pop3 } passdb sql { args = /usr/local/dovecot/etc/dovecot-mysql.conf } userdb passwd { } userdb sql { args = /usr/local/dovecot/etc/dovecot-mysql.conf } } It seems to work, but I have virtual users as well as system users. System accounts have their mail stored as follows: default_mail_env = maildir:/home/%u/Maildir While virtual users have this: default_mail_env = maildir:/htdocs/virtual/spool/%d/%u/Maildir Now, virtual users can login because I have used their $default_mail_env in my configuration. I am stuck how to get system users to successfully access their e-mails. Here is the error I get: beastie# telnet 0 110 Trying 0.0.0.0... Connected to 0. Escape character is '^]'. +OK Welcome. Dovecot is Ready to serve. user wash +OK pass a_verysecret1 +OK Logged in. -ERR No INBOX for user. Connection closed by foreign host. In the log file, here is what I see: dovecot: Nov 19 23:22:11 Error: pop3(wash): mkdir(/htdocs/virtual/spool//wash/Maildir/cur) failed: Permission denied dovecot: Nov 19 23:22:11 Error: pop3(wash): mkdir(/htdocs/virtual/spool//wash/Maildir/cur) failed: Permission denied dovecot: Nov 19 23:22:11 Error: pop3(wash): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. ... which is wrong, since mail for user "wash" is in /home/wash/Maildir. How do I make dovecot work in this situation?

[Dovecot] After restart dovecot do not serves IMAPS anymore
by Marian Hercek 02 Dec '05

02 Dec '05

I had to restart computer yesterday and now Dovecot has strange behaviour. Dovecot is running and should serve IMAPS, but client Mozilla Thunderbird cannot connect. I tried openssl s_client -connect localhost:993 and it said only CONNECTED(00000003). A time ago when everything was OK, the listing after connection was "a bit" longer than it is now. I remember there was "OK, dovecot ready" or something like that. Now, there is none. Of course in /etc/dovecot.conf: protocols = imaps imaps_listen = * ssl_disable = no So, what's the problem?

[Dovecot] Dovecot logs to syslog (other than MAIL)?
by Steve Bigley 02 Dec '05

02 Dec '05

I see in the config file where I can enable syslog, but then all logging goes to the MAIL facility. I could find no reference to changing the facility:level for syslogging. Is that implemented, or planned? I know I could just write it to a file, but I'd prefer to use syslog because then I can pipe it to a central logging server.

[Dovecot] Multiple Mailstores using 1.0alpha4
by Brian T Glenn 02 Dec '05

02 Dec '05

I am using qmail-ldap to provide virtual users to my system, but I also have some shell users on the system as well. Virtual users go into /home/vmail/mailstore/$username/ System users go into /home/$username/Maildir How can I have both of these available as inboxes in dovecot using ldap logins? Do I need to use namespaces or am i missing something with default_mail_env? Thanks, -- Brian T Glenn delink.net Internet Services

[Dovecot] Yet another silly question...
by Michael Segel 02 Dec '05

02 Dec '05

Ok, I now have Dovecot working but I'm having an issue with my start up from xinetd. I tried to follow the examples in the documentation, but why can't I just have a single entry for IMAP with just dovecot? Wouldn't this also open up the SSL and the POP3 stuff as well? TIA! -- Michael Segel Principal MSCC 312 952- 8175 [M]

[Dovecot] Unused SQL API
by Curtis Maloney 02 Dec '05

02 Dec '05

Greetings, recently I've been writing a database driver module for Dovecot to use SQLite. It's mostly for my own use, but I do recall other people have asked for this. Firstly - Timo, I grow to love your work more and more every day. :) I have not had any trouble figuring out what is needed of the driver, even without any API documentation. However, the one part of the driver that's given me pause has turned out to most likely be unnecessary. Whilst I was trying to work out how to deal with the sql_result->get_values() call without leaking memory, it seemed an odd method to have along side the other calls. So I decided to look for where it was used, to try to understand. Only, it isn't. The _only_ point I can find in the sources that calls that method is in the Postgress SQL driver. Am I missing something? -- Curtis Maloney cmaloney(a)cardgate.net
