Your mail server should not be accepting mail to nonexistent recipients. I know that's how Qmail works. It's broken.

Sadly, my courier server *is* accepting mail to non-existent recipients in my local domain. Any idea what I might have done to

screw it up?

If you're doing "@domain: account" rewriting, that account's home directory must have global read and execute permissions, so that courieresmtpd, running as a non-privileged user, can determine whether the corresponding .courier files exist.

No domain rewriting is going on, unless I've missed a default setting somewhere. I have one small set of users, listed without domain names, in userdb. I have 2 domains listed in locals (one whose MX records point directly to this server's dumb smarthost, the other from my old dial-up POP3 account, collected by fetchmail and being delivered via the dumb smarthost). There are a few aliases set up in aliasdir, but they all map user names 1:1 like the aliases/system file does.

Are you sure of that? A single, carefully chosen .courier file in aliasdir can swallow an entire domain.

Mail to non-existent users in domains listed in locals is

being accepted.

aliasdir/.courier-default

# ls -a /etc/courier/aliasdir . .. # find / -name .courier-default /home/bill/.courier-default #
