Frank,
I don't know of any particular problems with this setup...but first and
foremost, this does not appear to be a qmail issue. It appears to be a
Macintosh & DNS problem. ("because no answer was returned by
DNS")....e.g., the Mac thinks it's a DNS server for the zone which your
qmail machine is in, or it's "looking for DNS in all the wrong places".
Was the error message exactly as you reported it below?
"[EMAIL PROTECTED]"? If so, then there are some serious addressing
issues you need to resolve, since "alias.edu" doesn't exist.
Now, just because DNS is correct on your machine[s] doesn't mean that
the Mac is "seeing" that properly. You could try to convince the Mac
to send all messages via SMTP through your server--I would expect that
it's not a heavily loaded machine, since it /is/ a Mac. :-)
I would perform the following tests, just to verify that all of the
mailserver functionality is performing properly:
telnet to port 25 on the Macintosh from the qmail-machine.
telnet to port 25 of the qmail machine from the Macintosh.
if both of these tests can be performed successfully, your problem is
not an SMTP problem. (Of course it claims to be a DNS problem, so this
should be no surprise.)
Then, (do you have a server on the qmail machine?)...I would try
"browsing" on the FTP/web server on the qmail machine...force the
Macintosh to perform the DNS lookup. If you can connect using IP but
not using name, then the Macintosh is failing DNS lookups.
Next, (most troubling, error message, if you didn't doctor it), I would
find out why the Macintosh email server is trying to send stuff to
[EMAIL PROTECTED] instead of
[EMAIL PROTECTED]
At this point, you have found where your problem is. Anyway you cut
it, it doesn't appear to be a qmail problem, so your best bet is to
check out with folks in a mailing-list/group that concern themselves
with Eudora Internet Mail Server.
Good luck,
-Martin
