I am running Courier 0.39.1 on RH 7.3, we are only accepting mail for one
local domain (eg. localhost.com). Current using the default courier "catch
all" by placing my email/user in this file
/etc/courier/aliasdir/.courier-default . This has had the effect I wanted,
ie any email sent not going to anything legit goes to me so
dfs...@localhost.com will go to me even when there is no user dfsfa and the
sender never gets back a "unknown" response. The problems is that with SO
much spam it is hard for me to keep up with misspelled emails and such, to
make things a little easier would there be any way to keep this catch-all but
also send a "unknown recipient" response to the send? (that way senders that
are smart enough will just resend with correction)
No, and furthermore I don't even see the benefit gained in doing that.
First of all, return addresses on spam are likely forged, and bounce will
likely disappear anyway. Now, bouncing is the correct thing to do here, but
for other reasons.
Furthermore, if “senders that are smart enough will just resent”, then
there's no need to also waste time on the delivered copy of the message, so
you might as well just remove the catch-all, and bounce all crap back to
the sender.
