Migration from Courier to Dovecot with SquirrelMail

From: "andrew cooke" <andrew@...>

Date: Mon, 16 Apr 2007 22:53:19 -0400 (CLT)

With no apparent fix for this problem -
https://bugzilla.novell.com/show_bug.cgi?id=253437 - and "out of memory"
errors in SquirrelMail (when PHP has 256MB available!), and after reading
the comments here - http://squirrelmail.org/wiki/LowMemoryProblem - I
decided to switch from Courier to DoveCot.

Despite having a world of pain last time I tried this, it was a piece of
cake.  All I did was:

- stop the getmail cron jobs downloading email via pop from various places
- stop courier
- logout of squirrelmail
- stop apache
- uninstall courier, install dovecot (via Yast)
- tarball my maildir just in case
- delete every file from the maildir (and child directories - use find)
whose name begins with "courier" or "dovecot" (the latter from my previous
attempt to change over).
- run squirrelmail's config and follw the instructions at
http://www.squirrelmail.org/wiki/SquirrelMailAndDovecotIMAP (it's not
completely clear, but you can specify dovecot as the imap server name).
- restart apache
- look at http://localhost/squirrelmail/src/configtest.php
- start dovecot
- look at http://localhost/squirrelmail/src/configtest.php and see the
imap server
- login to squirrelmail
- subscribe to folders (note - if i tried to select all 200 or so folders
at once, this failed, but subscribing in groups of 10 or so was ok).
- restart getmail cron jobs

It is noticeably faster, there's no famd error messages in my mail log, I
haven't (yet) seen the memory errors, and there was no further config
needed.  Seems like a good deal.
