The Mozilla newsgroups don't seem
to have an answer to this problem.
Neither does my ISP (we pretend to support
Netscape, but not Mozilla)
Mac OS 10.1.5, Mozilla 1.4
Usenet posts are no problem, sending or getting.
Receiving e-mail, no problem. But sending e-mail
No time outs, just keeps on saying
that a send is in progress. For many minutes
if I let it.
Studied the account settings several times.
As far as I can tell, they are the same as
those in Mail.app which has no problem sending.
