I have two machines: one for mail and one for web/dns. They both have the same domain, but different hostnames (mail.mydomain.com and web.mydomain.com). I access ISPConfig by https://mail.mydomain.com and https://web.mydomain.com. Will this cause problems? When I try to go to use webmail (https://mail.mydomain.com/webmail), it times out. Also, I'm having trouble getting new mailboxes to work in each of the sites (ie. email@example.com works, but firstname.lastname@example.org doesn't). I have several domains set up on both the mail and web/dns box, and I didn't do anything special to do virtual hosting. I just added new sites to the same client and used the same IP. Any ideas what I'm doing wrong?
