This is really wierd behavior. I hope someone has seen this or knows the answer. Some background:
I recently put all of my computers behind a router. They were directly connected to the internet (via the university LAN). sendmail worked perfectly. Once I installed the router, they no longer had real host names. So I got the normal errors about having an address that didn't show up on DNS. I fixed that...or at least I thought I did.
The setup:
I have all mail that is delivered to my computer forwarded to my e-mail account (e.g. sohmc[_AT_]cs.umd.edu). Manually sent mail from my computer (root@foxtrot, root@localhost) gets successfully parsed and forwarded to sohmc@cs.
Cron is the bigger problem. Some cron jobs successfully send mail to sohmc@cs without problems. Others, however return this error:

Now the funny thing is, this bounce actually gets delivered to sohmc[_AT_]cs.umd.edu
It doesn't bounce back to root@localhost.
Thoughts? thanks!
