I have configured three domains (say domain1.com, domain2.com and domain3.com) on the zimbra server. I have pop and smtp *ssl* (using outlook SP2) access to the first domain domain1.com using the default mail.domain1.com as the server. However I cannot access the other domains through my mail client(pop and smtp access) except through the webmail client. Is this how zimbra works or what settings do I need to change this. I have Open Source edition.

Thanks a lot.
