I am assuming that these users have system accounts. Is that really necessary? Could you use "virtual domains / non-unix accounts" to handle them instead? You could employ MySQL with Postfix and Dovecot to easily handle that chore.

Please don't top post. If you don't know what that means, Google for it. Losing the HTML crap would be a good thing also. This is a mail forum, not a web page.

I don't comprehend your problem. You only have two hundred users, all with system accounts and the ability to log in I assume. Just let them change their own passwords. Why isn't that feasible?

I use squirrelmail for web-access and use passwd plugin to let people change their passwords. No shell access.

New subject: [Dovecot] Error - Mailbox conversion: Failed to create destination storage with data

Tere.

Using the latest v1.0.rc30, I'm trying to convert all users mbox -s to maildir with Dovecot -s convert plugin (setup from http://wiki.dovecot.org/Plugins/Convert). But seems Dovecot can't create the needed maildir folder into users homedir, as I'm getting the error:

dovecot: Apr 06 15:16:13 Error: POP3(spam): Mailbox conversion: Failed to create destination storage with data: maildir:/home/testMaildir dovecot: Apr 06 15:16:13 Error: child 7290 (pop3) returned error 89

Creating manually the "Maildir" folder into user homedir, the conversation works. On the other hand, Dovecot is capable creating folder "mail" into users homedir?

Any hint to fix it?

And should the /var/spool/mail/test be automatically deleted by Dovecot after the conversation is done?

Is the '/' really missing from test/Maildir or did you just break it
when copy&pasting?

No.

It's a typo from copy&paste correct is - dovecot: Apr 06 15:16:13 Error: POP3(spam): Mailbox conversion: Failed to create destination storage with data: maildir:/home/test/Maildir

No.

Ok.

Pathed the v1.30 failed:

patch -p0 < paik patching file convert-storage.c Hunk #1 FAILED at 251. Hunk #2 succeeded at 278 with fuzz 2 (offset -3 lines). Hunk #3 succeeded at 289 with fuzz 2. 1 out of 3 hunks FAILED -- saving rejects to file convert-storage.c.rej

But I added it manually, and it works great, Maildir will be automatically created thank You.

New subject: [Dovecot] Outlook: incoming mail lands in "sent" folder

The first word of the subject line probably says enough and shows my predisposition. Actually I used to like Outlook until we switched to IMAP, at which point my love turned to hate.

I have a single user on Outlook 2007 complaining about (a) mail "stuck" in the outbox that is not delivered (until we reboot windows) and (b) mail showing up in the "sent" folder that was not originated by this user (as in "incoming mail"). Neither of these issues are consistent, but I have seen them with my own tired eyes.

The user employs a horrific combination of Outlook and Act! (CRM with a pathetic Outlook clone which pitifully replaces the Outlook UI). They also have Outlook clients on two other machines.

They have three accounts on the same server. It's only happening on one of them. We've turned off Outlook "rules" completely to be certain it's not user-induced.

The probability of these two issues being Dovecot (or SMTP for the outgoing issue) are about as high as the existence of an orbiting teapot, but to satisfy the user and hopefully wean them off the Outlook drug I must show that the server isn't the culprit. Therefore I must do some very fine logging, but for this users' account only.

Is this level of logging possible?

- per user
- per function
- excluding spam processing

Have others (perhaps countless?) encountered these same issues?

Finally, why does Outlook suck?

Finally, why does Outlook suck?

Outlook is - and always has been - designed first and foremost as a client for Microsoft Exchange.

It actually works very well in that environment. It also woakrs reasonably well as a standlone POP client, but its IMAP support has always been lees than happy-making.

I'll be *really* happy when the Mozilla Sunbird Project is mature, and Lightning is a full featured, fully functional Calendar extension for Thunderbird.

Best regards,

Charles

a) rawlog logs all the IMAP traffic: http://dovecot.org/bugreport.html

b) mail_log plugin: http://wiki.dovecot.org/Plugins/MailLog
