Fetchmail problem: connection to localhost refused

[johnrchamplin@columbus.rr.com]

Fetchmail, for reasons I can't figure out, has started refusing to download mail. An identitical .fetchmailrc works on a different laptop, both running uptodate sid.  Here's a sample error message:

2 messages for JohnRChamplin at pop-server.columbus.rr.com (11760 octets).
reading message JohnRChamplin@pop-server.columbus.rr.com:1 of 2 (4264 octets
)..fetchmail: connection to localhost:smtp [127.0.0.1/25] failed: Connection
 refused.
fetchmail: SMTP connect to localhost failed
fetchmail: SMTP transaction error while fetching from JohnRChamplin@pop-serv
er.columbus.rr.com and delivering to SMTP host localhost
fetchmail: Query status=10 (SMTP)

Got clues?

P.S.
I'd be grateful if you'd copy me at JohnRChamplin@yahoo.com.
