Not sure where the "reject_unverified_sender" came from but the error = you are getting is that this is not a valid smtpd restriction. The message = was blocked with a 4X error so their server should try again.
I would edit main.cf and remove the "reject_unverified_sender" = restriction until you find out what it is supposed to be.

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=3Dimail.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=3D<[EMAIL PROTECTED]> to=3D<[EMAIL PROTECTED]> proto=3DESMTP helo=3D<ipswitch.com> Thanks, Eric Yellin
