I am tryingto configure Postfix to allow a remote client to relay mail.
I am using CENT OS 5 with Webmin/virtual min as my webbased admin tools.
The users are ably to pop/imap in and get their mail. I can send mail localy but not from a remote client like Outlook.
it is using postfix as my outgoing mail service.
When I added the domain I did so through Virtualmin.
