[imp] Migration from Squirrelmail?

[Jason Lohrenz]

Many hosting companies use horde, and I use PLESK which has one install that
handles multiple domains.  It is all in how you config the files.  You can
put in server variables (php) for items so that it will grab the domain that
is viewing the pages...etc..

Subject: [imp] Migration from Squirrelmail?

I have been looking through the documents out there and haven't been able to
find anything to help with a large migration to Horde/IMP from a
SquirrelMail environment.  Anyone have any pointers/gotchas?

For virtual hosting, do I have to setup an instance of Horde/IMP on every
single virtual host?  What I had done with SquirrelMail in the past was use
Apache redirect to have all URLs like:

http://www.virtualhost.com/webmail/ or http://mail.virtualhost.com/

all redirect to:

http://www.webmailhost.com/webmail/

This way I only have to maintain one webmail installation for possibly 100's
of domains.  But I notice in Imp's server.php config file:

" * realm: What to append to usernames for preferences and Horde
  * authentication to prevent login clashes on virtual host setups."

" * maildomain: What to put after the @ when sending mail. i.e. if you
  * want all mail to look like "From: max at the-triumvirate.net" set
  * maildomain to "the-triumvirate.net". It is generally useful when
  * the imap host is different from the mail receiving host. This will
  * also be used to complete unqualified addresses in the compose
  * screen."

These seem to imply that I need a seperate servers.php config file for every
virtual host.  

I am not entirely sure if this is a concern for me.  I use qmail/vmailmgr
for virtual hosting and everyone's username is essentially unique because
their username is their full email address.

I really want to move to Horde/Imp as I have heard so many good things about
it, but these two are kind of show stoppers at the moment.  My apologies if
I missed some obvious documentation.

Thanks,

Josh
