Ok, after a few modifications I'm now getting some semblance of useful logging.
So I attempted to email from [EMAIL PROTECTED] to [EMAIL PROTECTED] The first time I did it, I got this: Jul 13 15:15:43 white sendmail[16713]: PAA16713: ruleset=check_mail, arg1=<test@ 207.141.63.120>, relay=black.chroamtic.org [192.168.0.69], reject=501 <[EMAIL PROTECTED] 141.63.120>... Sender domain must exist After reading the sendmail.org website, I figured out that it wasn't finding col.hp.com, so I put an entry in /etc/hosts for it. Then I did it again, and got the following message: Jul 13 16:03:15 white sendmail[1427]: QAA01427: ruleset=check_rcpt, arg1=<[EMAIL PROTECTED] ol.hp.com>, relay=black.chromatic.org [192.168.0.69], reject=550 <[EMAIL PROTECTED] m>... Relaying denied And I have NO clue how I'd go about fixing this on a Debian system. So I really have two questions: 1) How do I get sendmail to recognize names without evetering every place I want to email into the /etc/hosts file? (On all my other machines, as a side note, emailing seems to work fine) 2) Why the heck is relaying being denied to an address that is obviously in my domain? Lastly, I've seen a lot of talk about exim... Would it be easier to maintain than sendmail for what I consider to be a very simple setup? --Mike
