[imp] Welcome Message Personalization

[Gustavo Verduzco Vazquez]

Hi everyone!

I would like to know how to personalize the welcome message that appears in 
the login screen. I don't want only to modify the text, I want to give to 
any virtual domain using the IMP webmail interface a different welcome 
message.
Is it possible to use PHP variables as HTTP_HOST and such to detect the 
domain typed by the final user when is accessing his webmail so that it can 
give a personalized welcome message for that domain...
What I want is that is a user types in the url http://mail.domainone.com in 
the welcome message he will get something like:
"MAIL.DOMAINONE.COM
Webmail System"
and if another user access his webmail at http://mail.domaintwo.com he will 
get:
"MAIL.DOMAINTWO.COM
Webmail System".
Is it something possible or doable?
Your input on this one will be much appreciated!
Regards,
