Hi Kevin,

Thanks for the quick response.

We're migrating mail systems and as a result, we're dropping support for 
writing out procmail rules via the Vacation module and switching to a 
customized version of Ingo that writes them to a DB and then into 
timsieved. However, the migration is taking place over the course of a 
few weeks and as a result, some users will be on the new system while 
others remain on the old. We're routing IMAP connections by doing 
lookups to a MySQL database and returning simply a username if a user 
has been migrated and null if a user has not been migrated.  I have 
hooks running that work quite well to set the quota type and the address 
of the various mail servers based on the result of this lookup.

Basically, what I want to be able to do now is to present a link to the 
Vacation module if a user is old the old mail system and I want the link 
removed if a user is on the new system. Thus, it isn't viable for us to 
really go to the trouble of tying all of this into the Horde user 
management system if it isn't necessary.
