[imp] Login errors after 4.0.4 to 4.1.1 upgrade...

[Michael M Slusarz]

Quoting Mike Cisar <mlists at starmania.net>:

> Current system configuration is Horde 3.0.10, IMP 4.0.4 and Dovecot
> 1.0.beta2, using IMP to handle authentication.  The system runs webmail for
> the server's main domain and several virtual domains.  When we originally
> converted this server from WU-IMAP (VIMAP) to Dovecot we had to jump a few
> hoops to make things work consistantly (effectively symlinking the base
> domain's mail spool and home directories into appropriate spots in the
> virtual domain structure... so for all intents and purposes Dovecot is
> treating the base domain's email as virtual).  Once we did this the webmail
> just worked without modifying our long-running webmail configurations.  It
> has been running in this state for a number of months and it should be
> mentioned that both IMAP and POP3 work just fine against both base and
> virtual domains with Outlook and Outlook Express (and I'm sure some other
> mail clients as well, we have had no user complaints).

> We tried in the last weeks to do an upgrade to IMP 4.1.1 but have run into

You haven't upgraded your servers.php file.

You should not be using 'imap_config' unless you know what you are doing.
You probably need to read imp/docs/UPGRADING.
