Re: Blocked MTA-BLOCKED

amavis is sending the messsage back to postfix after checking it

amavis has to spawn fewer processes than postfix wants to accept.

test this in /etc/amavis.conf:

Code:
$max_servers = 5;     # num of pre-forked children (2..30 is common), -m
$max_requests = 10;   # retire a child after that many accepts (default 20)

Re: Blocked MTA-BLOCKED

Does this tutorial help? Make sure you have same numbers in Postfix and Amavisd.
