[IMail Forum] Mail Relay Question

[Orlando Gravely]

I understand the best way to have IMail relay messages is through addresses if you want to stop a lot of spam, and also if you want to use it as a backup server for another mail server. My problem is I have a lot a virtual hosts and the address file only accepts up to 100 entries. I can also get the end users on the virtual domains to authenticate when sending outgoing emails through the server but the problem is the authentication only takes place on the default mail host. The other virtual host are unable to authenticate when sending out email. Is there a way to get around this problem.
