Hi. I'm no expert at this, but I'll explain my problem the best I can.
My site runs VM/CMS and an NNTP (I think) server for Usenet. Whenever
I try to e-mail from the Post command in the Usenet environment, my
message gets sent back to me as a "punch" file stuck in no-man's land.
It apparently never reaches its destination.
 
Some things have occurred to me: First of all, the VM/CMS we use requires
"at" rather than @ to send mail in normal, non-Usenet mode. So I changed
the @ in the Usenet mail header to "at." Nope, incorrect syntax.
 
Then I exited Usenet and entered the command "term chardel off," which
apparently allows @ in e-mail addresses. Went back into Usenet, and still
no go.
 
Any suggestions? Thanks...
