You can, in addition, specify "Loopcheck= None" to disable everything /Eric ----------------------------Original message---------------------------- (...) LISTSERV looks into the body of the mail, in an attempt to recognize mail that may be looping between a LISTSERV list and a foreign mailer. Quite a few checks were put in as part of 1.5l, but they don't apply to your 1.5i system. The only pre-1.5l checks I can recall are that the body must not contain either: 1) "From: <list>"; or 2) "Sender: <list>" where <list> contains: ({x} means "x is optional") 1) {"<"}<listname>"@"<listnode>{">"}; 2) {"<"}<listnode>"!"<listname>{">"} (for UUCP bigots); or 3) {"<"}<listname>"%"<listnode>{">"}. Perhaps you might find an incentive to upgrade to 1.5l in the fact that it offers a new list keyword, "LoopCheck = {Full / NoBody / NoToCount}, MAXTO(nnn)". With LoopCheck=NoBody, the above checks are suppressed. Ross Patterson Rutgers University
