[horde] question concerning hook, from_addr without ldap

[Andrew Richey]

         Hello guys,

         I've been looking for a few days and haven't found anything, 
so please forgive me if I'm posting something that has been answered 
already.  I'm trying to set up a hook for horde that will 
automatically set the from address for those users on their first 
login.  There are many posts on this, but most of which seem to deal 
with retrieving information from an LDAP server.

         I'm running Horde Groupware Webmail Edition on FreeBSD 
6.2.  This box is separate from my mail server, and it uses IMAP to 
access it.  We only have one domain here, so I simply need to set 
each users from_addr to their username (what they login as - their 
username) @ our domain (coe.fsu.edu).  It may be the case one can use 
a variable in prefs.php instead of creating a hook, but if so I'm not 
sure what it is.

         I have a feeling this is probably just a few simple lines, 
but I'm clueless as to how to do it!  Any help would be greatly appreciated.
