hmail: SMTP connect to localhost failed

[Richard Croy <R.J.Croy@massey.ac.nz>]

Hello,

I have been using fetchmail to pop mail into exim without problems for a few
years now.

But recently I started getting this error:

Reading message r.j.croy@its-xchg5.massey.ac.nz:1 of 238
(17205 octets) 
fetchmail: SMTP connect to localhost failed
fetchmail: SMTP transaction error while fetching from exchange.massey.ac.nz
fetchmail: Query status=10 (SMTP)

and I don't know how to fix it.  I suspect something has been broken by a
recent apt-get upgrade, which upgraded exim.

I think that the problem is that fetchmail cannot connect to localhost:25,
but I don't understand why this is.  It has worked fine until now, and I
have not changed anything myself.

I am running Debian Woody.

Any help would be much appreciated

Thanks,
Richard
