Does anyone out there know how to use IP addresses (e.g. 128.121.51.2) in
mailing addresses. One would hope that since you can telnet to such numbers
you can mail to them.
Thanks.

Sure, you just mail to user@[11.22.33.44] . Often you'll be stymied by the remote SMTP server, though, not recognizing such names as local, so you may get rejections from Sendmail saying that it refuses to talk to itself. There's no cure but for the target administrator to fix the sendmail.cf file to recognize explicit dotted-quads, alas, and that notification is hard to do when the whole problem is to get mail working in the first place. Admins, check your config files! Can you accept mail to your IP addresses? Craig Everhart

If I try this, it will be shipped to our central mail-machine for our domain, who will resolve the IP-number to a name, and lookup that name. In my case it doesn't exist so I get a 'failed mail' back. Also using tcsh, I had to use 'user@[xxx.yyy.zzz.ccc'.
