Yes, to clarify what I stated in the sentence you quoted, courier delivers an
email to the user aathan, but it contains what's below the *******. Anyway, that's what I get when I use the "Deliver all mail to that
user" setting in the web administration screen for the "@memeplex.com: aathan" alias entry.

This option seems to essentially create entries in /etc/courier/aliasdir that
resolve to the recipient to "&aathan". When I use the other option, and also create some .courier files (see below) in ~aathan that
contain "./Maildir", then I get the 450-Service temporarily unavailable response.

This is rather frustrating. I'm about to recompile this with -g and see if I
can get to the bottom of it in the source code!!!!!!

[aathan@home ~]$ ls -l .courier* -rw-rw-r-- 1 aathan aathan 10 Nov 20 23:48 .courier -rw-rw-r-- 1 aathan aathan 10 Nov 21 03:04 .courier-default -rw-rw-r-- 1 aathan aathan 10 Nov 21 02:49 .courier-memeplex:com -rw-rw-r-- 1 aathan aathan 10 Nov 21 02:53 .courier-memeplex:com-default

[root@home .courier-:webadmin]# echo "To: aat...@memeplex.com" |
/usr/lib/courier/bin/sendmail 450-Service temporarily unavailable. 450 Headers specify no receipients. sendmail: Unable to submit message.
