comment Does postfix cache RBL queries?
Thanks a lot, that makes sense; I have now flushed the server DNS cache to see if the issue is solved. As far as max_use and max_idle are concerned, I have already tried to restart postfix to no avail (I guess those values are reset upon restart, aren't they?).

comment Postfix acts as sender for unathenticated connections on port 25 for $relay_domains
I try to explain myself better with an example. If I set up my Thunderbird to use my email server as SMTP with no auth and port 25, I can send email to a known address belonging to my email server. Is this expected behavior?

comment postfix pcre conditional REPLACE
So it seems header_checks is no good to my needs, isn't it? Can you suggest a way to have a conditional replace among header fields (matching a different header line)? Thanks in advance for any help you will offer.
