Don't assume that your RSCS is involved in the mailing of traffic to
"INTERBIT"
I sent a message to 00000000@INTERBIT and (L)MAILER reported:
* Mail forwarded to SMTP@PSUVM
* From SMTP: Mail delivered to: <@INTERBIT.CREN.NET:[log in to unmask]>
Our default .BITNET mail traffic is routed to INTERBIT.CREN.NET which
apparently is a Princeton University site:
dig interbit.cren.net mx
interbit.cren.net. 14400 IN MX 10 outbound.princeton.edu.
(I still have not received the "bounce" from my test message.)
