"Unknown host" on outgoing emails since upgrade

[Anthony Campbell <a.campbell@doctors.org.uk>]

I upgraded Slink to Potato but still use smail because I can't get exim
to work with fetchmail.

I also use mutt.

Only one of my 3 ISPs works properly. I can send mail out from Freeserve
but from the others the mail is rejected with "Unknown host".

There must be something wrong with my configuration but what?

Any suggestions?
