I assume you mean you are trying to avoid sending mail causing a dialup.

My config does this. You might like to check it out and tell me which statements
are not needed or incorrect.
I also have a little script to check and send the mail, either as a forced check
(ie. will bring up the line and fetch and send mail), just a check (ie. bring up
the line and ... if mail is waiting) and check only if line is up.

They are included below.

File is called /etc/sendmail.mc:

Some points to note are:

1) Your masquerade domain is probably not pobox.com.
2) You probably don't have an internal domain called 'bogus'.
3) The LOCAL_RULE_1 is a fix for a problem with pine. I can't remember what it
fixed or where I got it, but I leave it in anyway.
4) I have not talked about address translations done by 'genericstable' and
'virtusertable' which I kindof use!
