Hello World,
I'm running Postfix 3.6.4 in a container on Alpine 3.15 main. After
a bit of time, I'm starting to get error messages like that:

Don't do that. It basically tells your Postfix to lookup all mails for

I'm not evil, I'm ... differently motivated!
When I submit a mail to my Postfix server (using SASL auth over a TLS
connection), Postfix adds the following received header:

Given no external interference, are queue IDs unique within a single
instance for the whole span a message stays within qmgr's control, or
can a mail in e.g. the deferred queue, share an ID with a message in
the active queue?

rbl_reply_maps overrides default_rbl_reply for blacklist/response code

Is it possible to specify a numeric code which is NOT a reject code,
thereby realizing a DNS whitelist?

currently receiving in a temporary file. That seems to imply that

While I certainly like the fact that Postfix becomes more and more
"admin friendly" in that it now also logs warnings about performance
issues, I'd like to know how many milliseconds a single request to
update the temporary whitelist may take before a warning is emitted.

If Postfix was operating in stress mode, you would see "-o

At this point, I'm almost about to ask you for output of "postconf -n"
and the content of any relevant maps involved in the relay attempt and
the relevant log entries, because I suspect a mis-use of the different
