I installed IMGate a couple days ago. I started out using the default IMGate main.cf file. Spam started being blocked immediately. However it seems like it's over blocking. I discovered that legitimate emails were blocked as well by the "reject_unverified_sender" command.
Here's an example of an Ipswich support incoming message being blocked: Feb 20 17:18:22 mx1 postfix/smtpd[522]: connect from imail.ipswitch.com[156.21.1.5] Feb 20 17:18:22 mx1 postfix/smtpd[522]: E8723248A6: client=imail.ipswitch.com[156.21.1.5] Feb 20 17:18:51 mx1 postfix/smtpd[522]: warning: unknown smtpd restriction: "reject_unverified_sender" Feb 20 17:18:51 mx1 postfix/smtpd[522]: E8723248A6: reject: RCPT from imail.ipswitch.com[156.21.1.5]: 451 Server configuration error; from=<[EMAIL PROTECTED]> to=<[EMAIL PROTECTED]> proto=ESMTP helo=<ipswitch.com> Thanks, Eric Yellin
