Troubleshooting SMTP

[rob@xxxxxxxxx]

Got one trading partner that is not getting our email.

06/03/2004 09:56:28   Router: No messages transferred to PPLASTIC.COM 
(host mail.PPLASTIC.COM) via SMTP: The server is not responding. The 
server may be down or you may be experiencing network problems. Contact 
your system administrator if this problem persists.

said it was "Apparently OK!", and it only had one minor irritant with it's 
failure to understand the ESMTP EHLO greeting.  But I've read that a lot 
of people turn that off and I don't think it's a big deal either.

Mail stays stuck in the various mailx.box files on the Domino server.

Where do I go from here?
