Hello, I've followed this HOWTO and everything is working fine. I can send and receive, I can identify spam and log into POP3 accounts as well as forward one domain to another server. However, I was wondering if there was a way to have e-mails arrive for several different domains into the spam filter box and forward onto the required smtp servers but have it so that the mail server will flag spam mail as spam and pass it onto a [email protected] account held on the local box. On top of that I was wondering if there is a way to have users from any domain create and maintain a whitelist/blacklist of their own, potentially via mysql, that will only apply to e-mails sent to the specified domain. Apologies for asking so much. If there is no way under the current configuration to do this, does anyone know of a way to achieve these goals using a different set of programs or OSs etc. Basically, I need a mail server that can accept mail for several different domains and forward on the "good" e-mail to their mail servers and filter off the "bad" e-mail into a local account so the users can login the webmail on the server and delete/release e-mails as required. Thanks in advanced for any help on this.
