Virtual domains and IMP.

[David]

Hi,

I have IMP running on a mail server for a primary domain but now some 
virtual domains hosted on the same server want to use webmail as well. 
After logging in as a user belonging to one of the virtual domains, when 
a message is composed the primary domain is loaded not the virtual 
domain. Can I rectify this somehow. At present I don't have the facility 
to change the senders address enabled and would prefer not to enable this.

I  looked at the archives but can only see discussions on Cyrus etc. As 
the server is in production major changes are not really an option. I am 
hoping I have missed something simple in the conf's. :)

The server is running sendmail 8.11, imp-2.2.6-1rh7 on RedHat obviously.

Thanks.

-David.
