[imp] serveralias

[Peter Mueller]

hello

i install horde and imp on a subdomain for example webmail.domain.com. this 
was functioned correctly. then i want that another domain 
(webmail.domain1.com) can utilize horde. i make this with serveralias.

after login on webmail.domain1.com (it doesn't functioned also in 
webmail.domain1.com/horde/imp/login.php) the url change to webmail.domain.com.

have somebody an idea where the problem was?

thanks in advance.
