Thanks for responses to my recent query on changing from: field on outgoing Listserv distributions. We run SMTP 2.2 so I suppose I now have to delve into the arcane world of rewriting headers. Although this is not the list for such discussions if anyone has a rules file that will ensure Internet style addressing and strip the .Bitnet off outgoing Listserv stuff I would most appreciate it. SMTP comes with "default" rules values but where these are stored is anyones guess as no actual rules file seems to kom mit. Does this mean I would have to copy by hand all the default rules into a file just to make my own mod ! What a drag. I was hoping to avoid such horrors. Eric's suggestion of setting parms in the list themselves I will look into also. Yes, we are on 1.7f. Santa did not bring me any cash this year. How many lumps of coal does it take to buy 1.8 ?
