[horde] expand_from and pref_uid

[adam]

Hi guys,
I'm a bit stumped.
I've used the expand_from address to get our actual email addresses
which are in the format 'first.last at mail'.
However, when I try to use turba, or even horde_prefs, horde trys to use
'First Last at mail' as the owner_id.  
Users login using 'First Last', so I at least 
understand where this is coming from.  I was wondering if someone could
help me to figure out what else I need to change in order to make this
work.  Should I just convert the database (updated from imp 2.1) to use 
'first last at mail'?
I understand that in the CVS there is a hooks.php with some further 
functionality in this area.  Could that be my solution?

Thanks,
Adam

convention, and conveying the same information in headers exposes it to
mangling and makes it rather less conspicuous....
