I am configuring postfix and amavisd on different serversa and am getting the below error:

Oct 19 14:47:48 server01 postfix/smtp[13541]: 31EB2130879: to=<eto@test.com>, relay=192.168.20.155[192.168.20.155]:10024, delay=46, delays=0.28/0.03/0.01/46, dsn=4.5.0, status=deferred (host 192.168.20.155[192.168.20.155] said: 451 4.5.0 id=01754-01 - Temporary MTA failure on relaying, From MTA() during fwd-connect (No greeting, dt: 35.008 s): id=01754-01 (in reply to end of DATA command))

Any idea on this?

- Do you have Amavisd listening on port 10027 on those two servers?
- You have "$max_servers = 2;" in this Amavisd server, may i know the amavisd related settings on the Postfix server in file /etc/postfix/master.cf?

"with success" or "without success"?

I have no idea yet, sorry. I suggest asking in Amavisd mailing list instead.
