[fetchmail]Patch: don't exit at a DNS-error at startup

Hi,

I've been bitten by a problem where my whole list of mail-accounts hasn't
been checked for a time because one mailserver wasn't resolvable due to
provider problems.

I always got the message "couldn't find canonical DNS name of xxx" directly
after startup and fetchmail exited with PS_DNS.

I think the correct behavior should be to print out an errormessage like
that and skip this host but poll the others.

So I wrote a patch which does exactly that (at least I hope so...).

Would you fetchmail-gods please take a look at it and tell my if it could
have unwanted side-effects like missing an alias for multidrop or something
else.

Thank you.

Regards,

Gerd
