We're having some issues sending emails with smtp on our Debian 6.0.7 VPS server (with Parallels Plesk).
Sending emails via the webmail application is fine, but when it comes to using a client such as mac mail or outlook we get unknown errors such as "The recipient ****@***.com was rejected by the server because the user is unknown."
I look forward to hearing from smtp experts!
