I think pop server and sendmail problem are not related... If you can still sendmail logged in Linux, look in /etc/sendmail.cf for lines starting with "F". They are well commented:

# file containing IP numbers of machines which can use our relay
F{LocalIP} /etc/mail/ip_allow

If you can't send mail from the Linux box, edit /etc/sendmail.cw and add things like your full domain name, localhost, and try again...

Good Luck

Sorry I didn't explain: RedHat has it's sendmail configures for not to relay mail because of the commercial spam out there...

I don't think it's a Good Thing... You can enable relay by domain or by ip (just put one domain/ip per line in the files referenced to by F{LocalNames}, F{LocalIP} in your /etc/sendmail.cf)

But if you still want to make it relay to everybody, MAKE A BACKUP COPY of /etc/sendmail.cf and then remove all lines begginig with "F" and look for "Ruleset 98", go ahead and remove from "Special rules when relay control is active" to the next ruleset... Again I think it does no good...
