Before trying to Luis' suggestion, I had the following in /var/log/messages: dovecot(pam_unix)[4691]: check pass; user unknown dovecot(pam_unix)[4691]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= dovecot-auth[4691]: pam_ldap: could not open secret file /etc/ldap.secret (No such file or directory) I suppose the first two entries are the lookup for the dovecot user in the DS, where it doesn't exist. And since I want anonymous binds to the DS, I haven't created file /etc/ldap.secret. Users were able to authenticate and get their mail. After changing to auth_userdb = passwd, all the messages went away, but the users weren't able to get their mail: Evolution gave me the following error: "Unable to get a valid greeting" from the mailserver. I went back to auth_userdb = ldap /etc/dovecot-ldap.conf, and then back to auth_userdb = passwd. Users can get their mail, but the messages are back in the log file. I'd appreciate help in understanding this behavior. -- Oscar A. Valdez

[Dovecot] Test version for production servers for shared folders
by Gavin Henry 10 Apr '06

10 Apr '06

Dear List, Is the latest test version suitable for production systems? Our current servers use 0.99 on FC4 and we would like to add shared folders via the test version. Has anyone migrated this way before? Thanks, Gavin. -- Kind Regards, Gavin Henry. Managing Director.

by Sysadmin 10 Apr '06

10 Apr '06

Hello. Typical log text - top=0/0, retr=0/ del=0/0, size=0 I can figure out what means retr=0/ del=0/0, size=0, but what about top=0/0? It's static data, haven't seen any others numbers, than zeros there? -- Sysadmin

[Dovecot] Dovecot's as server based and mail filters and addressbooks holder?
by Sysadmin 10 Apr '06

10 Apr '06

Hello. I'm just wondering, that maybe is the time to change the imap -s format or add some more features, are in these day's most people, me also are so called mobile users. And imap is good solution for us but however still some basic things are missing, fore example: 1) Server side mail filters. I read mails from home, from office and from webmail. Now when I need to make mail filter, for example to collect all dovecot mails into one subfolder, I can do it in one computer, and they works, if the computer is online, but if I need to change them, reading email from the another computer, I can't do it. 2) Server side address book. Yes, I know, ldap is solution, but installing and configuring the ldap server for some simple global address book, is kind of overkill. And these rules/address book can be from client to see as subfolder, so every imap capable client can deal with them? Is this real on not? -- Sysadmin

[Dovecot] anyone running with Horde mail?
by Alan McKay 10 Apr '06

10 Apr '06

Hey again folks ;-) Seems my auth is working afterall when I telnet to the IMAP port. But darned if I can get it working with Horde web mail. Is anyone out there doing this just first of all to confirm to me that the combination works OK. I don't care so much about shadow auth since apparantly my pam auth is working just fine. thanks, -Alan -- "True Budo is done for the sake of building peace.

[Dovecot] Missing X-IMAPbase header causing mbox corruption
by Con Tassios 10 Apr '06

10 Apr '06

If the first message in an mbox is deleted by an external program, therefore removing the X-IMAPbase header, an error such as the following occurs. Apr 9 20:10:51 sm1 dovecot: imap(306812): file mbox-sync-update.c: line 460 (mbox_sync_update_header_from): assertion failed: (ctx->mail.uid == 0 || ctx->mail.uid_broken || ctx->mail.uid == mail->uid) This prevents the user from logging in, but also appears to cause mbox corruption. If the X-IMAPbase and the X-UID headers are missing, Dovecot will insert them successfully, but fails to do so when only the X-IMAPbase header is missing. Using dovecot-1.0.beta3.

[Dovecot] quota reporting
by Mick T 10 Apr '06

10 Apr '06

Hi all, I'm wondering if theres a way to report the quota, but not enforce it? The problem is that i'm using dirsize as the quota method to calculate the size of the mail directory, and for very large mailboxes this can take time... what i thought would be good, would be if dovecot could report the quota when the user requests it, but doesn't calculate it for every operation it performs? Does any one have any suggestions? I'm using Dovecot 1.0 beta5 My config: mail_plugins = imap_quota quota The quota for a mailbox is stored in sql, and so the sql query returns a "quota" which is picked up by the quota plugin Michael
