[Dovecot] POP (dot) locks
by Christian Balzer 09 Apr '06

09 Apr '06

Hello, just to soothe my paranoia from many years of qpopper usage, which enforces solitary access to a POP mailbox. Only one login per user is possible at the same time and if a session terminates w/o qpopper being properly notified it will remain locked for some time, 30 minutes by default. With dovecot (0.99.10.4) one can login multiple times (using POP, with IMAP of course this comes as no surprise :) and thus I presume this bit from the configuration: --- # Should we create dotlock file even when we want only a read-lock? Setting # this to yes hurts the performance when the mailbox is accessed simultaneously # by multiple processes, but it's needed for reliable reading if no other # locking methods are available. #mbox_read_dotlock = no --- means that if the only other reading accesses to a (mbox style in this case here) mailbox are via other dovecot processes everything will be fine?

RE: [Dovecot] IMAP login name conversion

Unless you're authenticating from > SQL you probably have to modify the source. Let me explain: My server runs OpenBSD-3.5 and Sendmail. We host few virtual domains. Local accounts have login names in this format: login-domain_abc_xyz For example: joedirt-joedomain_com_au, info-adomain_com, info-otherdomain_com That way login accounts are unique across all the virtual domains. I use the OpenBSD pre-compiled dovecot-0.99.10p2. It is set to use "auth_passdb = passwd" and "auth_userdb = passwd" I can use mutt to access my mailbox via IMAPS with login name format joedirt-joedomain_com_au. Other users use different MUA like Outlook and prefer to login with their email addresses (joedirt(a)joedomain.com.au, info(a)adomain.com, info(a)otherdomain.com) We use squirrelmail for webmail. I modified squirrelmail to automatically convert login name from format of joedirt(a)joedomain.com.au to joedirt-joedomain_com_au. So if users use squirrelmail, they can just login with their email addresses. My question is how to achieve the same thing with other MUAs like Outlook? Do I have to modify dovecot source? Can I use LDAP or SQL instead? Note that we are using Sendmail and prefer it than othe MTA. I have looked at the Wiki, specially the "DovecotOpenLdap" but am still confused. Thanks Zoong

[Dovecot] Dovecot, Outlook Express and new accounts
by news.gmane.org 12 Nov '05

12 Nov '05

I have come across a strange situation, involving new accounts. I am running Dovecot 0.99.10-5 on Fedora Core 2. Dovecot is configured to use pam for authentication, and the dovecot pam service is configured to use pam_mkhomedir. When an account is created and the user logs in through SquirrelMail, there is no problem. The standard folders are available - Inbox, Drafts, Sent Items and Trash. When logging in through Outlook Express first, it gives the following error:- The server did not respond to this IMAP command before the connection was terminated. Configuration: Account: mail.server Server: mail.server User name: username Protocol: IMAP Port: 143 Secure(SSL): 0 Code: 800ccc0f A packet trace shows the following:- <<< * OK dovecot ready. >>> 008E CAPABILITY <<< * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED STARTTLS AUTH=PLAIN <<< 008E OK Capability completed. >>> 008F LOGIN "username" "password" <<< 008F OK Logged in. >>> 008G IDLE <<< + idling >>> DONE <<< 008G OK Idle completed. 008H LIST "" "*" Connection to host lost. My suspicion that Outlook Express is not intelligent enough to create the folders, although the sudden connection drop might indicate a bug. If it is not a bug, is there a workaround?

[Dovecot] problems with ldap auth
by Nuno Lopes 10 May '05

10 May '05

I'm trying Dovecot v1.0-test43 with ldap authentication but can't seem to make it work. I'm getting the following errors in the log: dovecot: Sep 16 19:50:09 Info: Dovecot v1.0-test43 starting up dovecot: Sep 16 19:50:10 Error: Auth process died too early - shutting down What can I do to see where the error is? I have this configuration working with dovecot 0.99.xx . And if I replace the ldap authentication scheme with another one it starts up right. Following some past mailing list sugestions I've also tried removing most of the auth modules from the compilation but it made no diference. You can see my configuration files in: http://iluvatar.portugalmail.pt/dovecot/dovecot.conf http://iluvatar.portugalmail.pt/dovecot/dovecot-ldap.conf (I've intalled the binaries in /opt/dovecot) Don't know how much more data I can provide to help finding out what the problem is here (I think this won't be enough unless there's a known bug). Thanks, -- Nuno Lopes

[Dovecot] imap idle on non-inbox?
by Collin Grady 22 Oct '04

22 Oct '04

Can this be done with dovecot? I really like the imap idle feature, but it doesn't work for me because I sort my mail into folders with procmail, so it only notifies me when one drops into inbox and not a subfolder. Is there just an option for this I'm missing, or does support for this not exist yet? Also, I don't think its a client issue as I watched the traffic with tcpdump and it only announced anything for inbox, messages dropping into other folders caused no traffic. -- Collin Grady BOFH excuse #347: The rubber band broke

[Dovecot] UIDL bug
by dovecot＠spam.turbolink.net 16 Oct '04

16 Oct '04

I noticed a problem with handling UIDL msgnumber in test46. If you do "UIDL 1" on a POP3 connection it returns the UID of the message followed by a dot and an error message. I made 2 changes: I added the following line to line 527 of src/pop3/commands.c ctx->message = message; I changed line 559 from: if (list_uids_iter(client, ctx)) to: if (!list_uids_iter(client, ctx)) Next time I'll submit an actual diff, I've made lots of other changes and comments in my source though so it's harder. - Mike

[Dovecot] Public folders / namespace documentation
by Keith Edmunds 04 Oct '04

04 Oct '04

Does Dovecot support public folders? I thought it may do via namespaces, but having searched the Wiki and the documentation, I can't find how namespaces are defined. I've probably not looked in the right place - any pointers? Thanks, Keith

[Dovecot] evolution and received by header
by Dan Stromberg 03 Oct '04

03 Oct '04

Evolution has a nice feature where it can sort messages by the most recent received-by date, instead of the Date: header. This is nice, because then if something gets stuck on a server somewhere in the world for a couple of days, it shows up at the end of your mail list, instead of way back where you might miss it. However, when using dovecot with evo, if I sort of received by instead of date, it takes forever. I assume this is because date is indexed, and received by is not. So the natural question becomes, is there a way of getting dovecot to index received by? TIA.

[Dovecot] Dovecot/IMP attachment problem
by Ryan Hulsker 01 Oct '04

01 Oct '04

I recently installed dovecot in my production environment. This comprises about 60k mailboxes. The system was initially set up with dovecot 0.99.10.7 using maildirs. I have been using perdition to handle redirection during the process of converting from wu-imap. Last week it was brought to my attention that our webmail interface (horde/imp) is no longer allowing people to download attachments. Everything appears to work fine, however the downloaded files are 0 bytes in size. I built a test box with the latest horde/imp/php combination and that failed to solve the problem. Today I upgraded dovecot on one of our mail servers to 0.99.11 and that seems to have had no effect. I was hoping that the BODY and BODYSTRUCTURE changes from 99.10.8 would have fixed this. I am wondering if anyone has encountered these problems? Is this a dovecot bug? Due to the fact that I am still in transition mode using perdition I am in the unique position where I can basically hit two identical mailboxes, one in wu-imap and the other in dovecot just by using a different username. I have done this, and have ethereal traces if anyone is interested in helping me out with this. Ryan Hulsker
