I telnet the server on port 25. Now the so called banner should be sent. But it isn't. So no chance to drop HELO. And after a while the connection will be closed.
Sorry for the noise, after three days the problem is gone. Suddenly as it came. Don't know. Maybe a spam attack. Thanks Theo.
Postfix does *not* fall over because of a "spam attack". It's designed to be able to handle 100s, or on very beefy hardware 1000s, of simultaneous connections per second I agree with the other repliers though, it was probably a DNS problem. One question: why didn't you post the output from the grep command as requested; do you really expect people to dig out an answer from their xtal bowls? Theo -- Theo v.
