I have a new server, and, have been trying to 'migrate' main.cf over to new server, few lines at a time; suspect might have screwed something in the process ? just noticed eleven similar rejects for what seems like valid email: Dec 16 23:07:02 emu postfix/smtpd[27747]: NOQUEUE: reject: RCPT from

Dear Gentle Folk, I operate a small farm of servers, all running postfix, sendmail (blech) or exim (blech**2). We ping everything every minute and if a server fails a ping x number of times I get beeped. This works well for hard downs, but a server can be pingable and still be v

Dear all, I have a very strange problem with our postfix server. It has been working for years without problem, but suddenly we started to have errors with SMTP connexions from outside. On the client side (we tested with Thunderbird and Outlook), the connection lasts many minutes before show

We're doing sender verification for our local domains, so a message sent from "f...@plexicomm.net" gets rejected. A message with an envelope sender of "va...@spammer.com" with a from: header of "f...@plexicomm.net" gets accepted. Is there a way to enable verification on "from:" header addresses
