[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

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

[Dovecot] MBOX to MAILDIR conversion
by Marc Perkel 05 Mar '07

05 Mar '07

Thinking about going from mbox to maildir. Started with mbox way back when but thinking about making the conversion. The main reason is that I use rsync for backups and when these huge mailboxes are touched I have to copy the whole thing. With maildir I only copy the files that change. So - my questions is - what's the easiest way to make this happan. I assume there are conversion utilities. I'm using Exim as an MTA. Also - using Ext3 for the file system on a Raid 10 array. Backup server will run Ext3 Raid 1. Is the number of files in one directory going to be a problem? And - any tip/tricks would be appreciated. Things to look out for? Still in planning stage. Thanks in Advance.

[Dovecot] Dovecot ignoring Quotas
by Frank Doege 03 Mar '07

03 Mar '07

Hi, i have installed the dovecot 1.0rc25 and everything is working well. I have connected it to a postgresql database. Now to my little problem: Postfix is delivering into a maildir folder with active maildirquota patches, and this is working well. The problem is only that dovecot is not recognizing the maildirquota file at all. I have configured it as in the documentation with Plugin { Quota=maildir } Anyone any idea ? maybe this is a bug ? Thanks

[Dovecot] Using auth_bind_userdn causes uid to be improper case
by Aaron Luchko 03 Mar '07

03 Mar '07

I'm having a problem with dovecot-1.0-1.1.rc15.fc6 + LDAP + auth_bind_userdb. I have the following /etc/dovecot.conf: mail_location = maildir:/var/spool/mail/%u/ protocols = imap pop3 mail_log_prefix = "%Us(%u):%i:%h " first_valid_uid = 5001 first_valid_gid = 5001 protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain userdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap.conf } user = root } dict { } plugin { } and /etc/dovecot-ldap.conf: hosts = driveable.example.com base = dc=example,dc=com #dn = cn=Directory Manager #dnpass = password auth_bind_userdn = uid=%u, ou=People, dc=example, dc=com uris = ldap://127.0.0.1 user_attrs = mail user_filter = uid=%u user_global_uid = 5001 user_global_gid = 5001 pass_filter = uid=%u The problem is that if we have an entry in LDAP, User Name, with the uid UName, postfix stores the users mail in /var/spool/mail/UName If I log into dovecot using uname (LDAP uid isn't case sensitive) than dovecot tries to look in /var/spool/mail/uname, similarly if I log in with unAME dovecot will look in /var/spool/unAME. However, if instead of using auth_bind_userdn = uid=%u, ou=People, dc=example, dc=com I bind with dn = cn=Directory Manager dnpass = password than it correctly looks in /var/spool/UName regardless of the case used when logging in. It seems like when I log in with auth_bind_userdn %u is being left as the value I logged in with rather than being reloaded from LDAP. I was wondering if I have made some mistake in the configuration files to cause this behaviour or if something else is going on? thanks, Aaron

[Dovecot] automaticly move expunded emails to trash Folder
by Wilfried BARNAVON (Perso) 03 Mar '07

03 Mar '07

Hi I try to migrate from courier to Dovecot. Is there a way to get the same behaviour of Courier-imap with dovecot, about expunged emails ? I though about using the Lazy-Expunge plugin. The problem with this plugin is the following: messages are moved and set to be deleted in the Trash Folder. I would like they weren't set to be deleted. Is there a way to mitigate the behaviour of this plugin, or is there another plugin having this task in charge ? Thanks Wilfried BARNAVON

[Dovecot] Struggle with Postfix/Dovecot-auth and SASL
by Ingo Reimann 03 Mar '07

03 Mar '07

Hi List, I just updated an old sendmail installation to a modern postfix/dovecot system with mysql backend. Everything works fine but SMTP-AUTH fails with some clients. The problem is, that with PLAIN (old) clients send the base64 coded form: USERNAME\0USERNAME\0PASSWORD which, as i understand dovecot interprets as MASTERUSER\0USERNAME\PASSWORD. New clients send \0USERNAME\0PASSWORD which works fine. I don`t like to use masterusers, because then everyone would be able to log in as someone else. When i don`t have a passdb with master=yes in my dovecot.conf, Dovecot complains auth(default): passdb(XXXX(a)YYY.TLD,master): Attempted master login with no master passdbs If i create a passdb with contains everyone, everyone may look into other mailboxes. No good idea. I can`t change the old clients, but for now, i don`t know, what i am doing wrong or how to correct it. No real HowTo for my setup on the net, it seems that everyone uses cyrus-sasl. May anybody help, because i don`t like to switch my setup or use 2 auth daemons.

[Dovecot] Stopping certain users from using IMAP, or POP3, etc.
by David Craigon 02 Mar '07

02 Mar '07

Hi there, I'm building a mail system for an ISP. We want to be able to turn on or off IMAP or POP3 access for certain customers- basically we want to be able to offer a customer POP3 access, unless they pay us some more money, in which case they get IMAP The username and password will remain the same, and are driven out of a postgres database. The best way I've though of doing this so far is by defining separate auth systems for IMAP and POP. Is this the best way? A gold star is available if you can think of a way that if they try and use IMAP but haven't paid for it it rejects them with "Give us all your money..." or some such.

[Dovecot] Deleting when Over Quota
by Daniel Watts 01 Mar '07

01 Mar '07

Hi All, I've read a bit about this but don't really see a full solution anywhere. Has anyone actually got a good fix for this? Telling a user they are over quota then not allowing them to delete anything does seem the height of perversion. =) Question is - is this even a problem for the IMAP server? Or should the MUA be detecting over quota problems and then issuing the right commands to delete messages WITHOUT the copy to Trash? Lastly - even if it is the MUA's responsibility - will Dovecot not still have a problem with indexes? I suspect perhaps not if: A. When using FS Quotas you store the indexes in a non quota partition B. When using other quotas (dirsize / maildir++), Dovecot does not count the index files when counting up the usage. Is B true? Best wishes, Daniel

[Dovecot] Still issues with new message count...
by Brian Taber 01 Mar '07

01 Mar '07

I am still having issues with new message count. When I move a message to another folder, it counts that message as new until you go into that folder. Is there a way I can solve this? Could it have something to do with NFS? I have tried all the NF workarounds with no luck... I have also tried NFSv3 and NFSv4, no difference. I store the indexes on the local drive...
