Hi John,
Reading the abstract of this document only, it was clear to me about
the intent of the codes and good to add to our SMTP package. But is
there a translation of what it means on the SENDER SIDE? Is it
permanent filter/block at the domain level?
In our mail package, and it has been relaxed slightly over the years,
once all outbound mail attempts were tried for a single transaction,
that domain/email is put into a "BadDomain" or "BadEmail" block list
to preempt future outbound attempts. Sysops are given an site URL
where they can check/manage/request the removal of this block. I
had long considered adding outbound logic to try sending at least one
time, and if successful, auto remove the block. But it really never
became a big thing for operators to have this advanced logic. Most of
the time, the blocks were permanently legit and/or they turn off the
the auto-blocking logic and just add it manually or feed the list file
name to some other filtering tool.
Having and using these reply codes would mean that the blocks are
permanently legit, correct?
Thanks
