- I have a mail problem. It has to do with domains and subdomains. My domain is
- 'gov', the subdomain is 'lbl', which is also the name of a computer at LBL
- (Lawrence Berkeley Laboratory) which stores what I call routing stuff so that I
- can send to anywhere in the world by just knowing the address and not having to
- load the whole world's internet numbers into my computer. The problem is that
- I can't properly take advantage of the database on lbl.gov. For instance, if I
- want to send mail to username@gav.gat.com (that would work fine from non-next
- machines at the lab), I have to 're-route' it by addressing it as follows:
-
- username%gav.gat.com@csa1.lbl.gov
-
- I realize that it works, but it seems to be clumsier than necessary.
-
-
- You can reach most people at lbl using username@lbl.gov addressing, and lbl
- will route their mail to wherever they like to read it. Therefore, I don't
- need to worry about what machine they read mail on (there are probably several
- hundred possibilities at LBL), as long as they are registered in the database
- on lbl.gov. Note that almost nobody has an active account on lbl.gov; the
- 'postmaster' there just pushes it around on our behalf. Unfortunately, all
- this doesn't work from next1.lbl.gov. For instance, if I try to reach someone
- who I know is registered in the lbl.gov database (I know this because I do the
- 'finger' command), the mail gets bounced back with a complaint as follows:

- ===============================================

- However, 'finger' led me to believe that it should work:
-
- next1# finger gelbaum@lbl.gov
- [lbl.gov]
- [isotop.lbl.gov]

- By the way, send to M_Gelbaum@lbl.gov yeilds the same results. Also, doing
- this using 'mail -v username@lbl.gov' gives the same results.
-
- So, for instance, my generic address is seidl@lbl.gov. lbl routes my mail to
- a sun workstation (seidl@ux5.lbl.gov), but it gets bounced back if I send to
- seidl@lbl.gov, (BUT seidl@ux5.lbl.gov works fine!)

- In case it helps, here are the first several lines from my sendmail.cf

- # If you want the gateway machine to appear to be INSIDE the domain, use:
