Hi.
I receive a lot of "NOTICE: mail delivery status" for unknown users
(cause of spammers). I don't want to remove administrative messages,
I need them to monitor my mail server, but I'd like to filter the reason
why I receive such messages.
Do I have to write a maildrop filter, or is there a faster way (like a
parameter in configuration files)?
Tony,
It sounds like you might be seeing the same problem I had a while back.
I'm sure it was due to a misconfiguration on my part, but I did come up
with a workaround (and probably still have the misconfiguration).
Anyway, I was accepting mail for a given domain, and assigned a few
aliases to that domain but didn't have a generic "@domain.com" entry in my
aliases file. To me, it looked like courier was then accepting email for
any address at the domain and then it bounced it around a bunch until it
ended up in the postmaster inbox as you describe. My workaround was to
put...
@domain.com: reject
...in the aliases file. There is no "reject" user, so courier bounces the
message at the smtp transaction with an "unknown user" error rather than
accepting it.
The missing "@domain.com" alias entry might actually be the original
misconfiguration, I need to go back and rtfm myself ;)
I hope this helps.
