-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, for a nice v1.0 release, there are some glitches in the example: 1) # allow shell access for users.

[Dovecot] File descriptor leak in 1.0rc2[45]?
by Victor Duchovni 06 Mar '07

06 Mar '07

I upgraded (NetBSD 2.99 i386) from 1.0rc7 to 1.0rc24 and then tried rc25, and in both cases need to restart Dovecot every day or so (low volume server). It seems to run out of file descriptors. I have now raised the file descriptor limit to 1024, but that is not a long-term solution... ...

[Dovecot] Migration
by John s 06 Mar '07

06 Mar '07

Hi, I have a Mailserver setup with Qmail+Vpopmail+courier-imap with 2000 users.The authentication in vpopmail was in plaint text file based.Right now the issue is while opening a user email box with 50-100 mails it is opening fastly.Butfor email-boxes with attachments and increased number of mails it take long time to open the Imap connection. So I would like to change the Imaps to Dovecot.Please suggest if I can migrate from courier-imap to dovecot with vpopmail and qmail without changing the present username and passwords. Thanks in advance for any help. Regards John

[Dovecot] new crashes: is the index/mail cache endian neutral?
by Dan Price 06 Mar '07

06 Mar '07

Part of our migration plan takes our users from one endianness to another (big to little). Will the index and mail cache files survive? I'm seeing some new core dumps as the first test user is migrated, which makes me think... not. What about if we want to build dovecot 64 bit in the future? Will that cause problems too? Stack trace is below the log messages. I've edited the user's name out and replaced it with foobar, and cleansed out a few sensitive things. -dp dovecot: Mar 01 08:46:49 Info: imap-login: Login: user=<foobar>, method=PLAIN, r

[Dovecot] messages lingering in .Trash/new instead of .Trash/cur
by Glenn Leavell 06 Mar '07

06 Mar '07

We're running Dovecot rc15 on Solaris 9, providing IMAP access to e-mail stored in Maildir++. I've noticed that a significant number of message files are currently sitting in the directories ~/Maildir/.Trash/new/. I would have expected that all messages in .Trash would be in the /cur subdirectory (as most are), and I'm not sure how they're landing in /new. If I connect to Dovecot and run something like the following, the messages all *do* immediately end up in .Trash/cur/ : x select blah * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags * permitted. * 4 EXISTS * 0 RECENT * OK [UIDVALIDITY 1150071896] UIDs valid * OK [UIDNEXT 5] Predicted next UID x OK [READ-WRITE] Select completed. x copy 4 "Trash" x OK Copy completed. Most of our users are using Thunderbird, and after looking at various outputs of rawlog, TB seems to be simply issuing uid copy commands to "Trash" like the ones above when a user deletes a message. Do any of you know what IMAP interaction with Dovecot can lead to message files appearing in .Trash/new/ ?

[Dovecot] Driving quota out of a database.
by David Craigon 06 Mar '07

06 Mar '07

Hi there, I'm using postgres as a userdb for dovecot. I'm am trying to get the quota plugin to work. I have a column in my table that returns the quota in KB. I am using the postgres expression "('maildir:storage=' || mailstore_control.mailbox.quota) AS quota" as recommended in the manuals. This expression is NULL to start with, which I take to mean unlimited quota. Trouble is, if I change it to a value, and then change it back to null, I don't seem to go back to unlimited quota. I'm using maildir++ quotas. What gives? :-) David Griffin Information Systems Ltd 20 St Christopher's Way, Pride Park, Derby DE24 8JY www.griffin.com <http://www.griffin.com/> Registered in England and Wales.

[Dovecot] Replacing qmail + vpopmail with: sendmail + dovecot
by Oliver Schulze L. 06 Mar '07

Hi, I wonder if it posible to replace qmail + vpopmail with sendmail + dovecot? The idea is like this: - use sendmail + milter API to filter spam/virus and deliver the email to the dovevot MDA (LDA) - dovecot should save the email to the directory as specified in the vpopmail DB - maintain the vpopmail BD (users + passwd) - use dovecot pop3/imap for the clients - use sendmail again to receive the email from the pop3/imap users and deliver the email to the internet as usual. Anyone has done this? It is posible in the paper, in the real world? many thanks Oliver -- Oliver Schulze L. | Get my e-mail after a captcha in: Asuncion - Paraguay | http://tinymailto.com/oliver
