zmailer bug reports..

I feel a bit funny, sending things like this to a huge mailing list.
Is there some better address?

Anyway, here's another anomaly: Sometimes the SMTP server doesn't
reply to VRFY and EXPN.  Uncompiled patch explains better than words:

To see the bug in effect, ask nic.funet.fi to EXPN 'zmailer'.
