Here is one of two responses on the UCLAMAIL list. Any comments Eric? Duane ----------------------------Original message---------------------------- On Tue, 30 Apr 91 14:09:49 EDT, "Duane D.

The fault is equally LISTSERV's. X-TO is the private protocol between UCLA/Mail and the UCLA ACP (and hence Acces/MVS). ACP converts SMTP MAIL FROM into X-FROM and SMTP RCPT TO into X-TO. UCLA/Mail uses X-TO to know who to deliver the mail to. This causes that unfortunate side effect with LISTSERV. When I figured out that's what was causing duplicate mail on MVSTCPIP, I put in * X-Tags= Comment in the list header, so the original header lines show up as "Comment: To:" instead of "X-To:". As long as the UCLA ACP, Acces/MVS, (now called SNS TCP Access by Interlink), and OpenLook from Network Solutions exist on the network, it is not safe to have lists set up with the X- option -- original header lines should be changed to Comment:. My personal opinion is that LISTSERV should not be changing the headers at all, but this is the wrong list for that argument. You should also beat on the vendor to accept and to generate BSMTP instead of the terribly obsolete X-FROM/X-TO protocol, since you probably can't get every list in the world changed. We're now running IBM's SMTP, which interfaces to UCLA/Mail via BSMTP. /Leonard
