It doesn't seem like that. I'd already established three ssh sessions to
three remote servers (zip, digeo, osdl) and fetchmail was able to contact
those three servers via connection to the three local ssh clients.
It was only when fetchmail tried to talk to sendmail on localhost that
things failed.

The problem went away on subsequent reboots :(
But the failure was when communicating with sendmail on localhost.
