I want to set MaxRecipientsPerMessage in sendmail 8.9.0, but I don't want to interfere with the distribution of listserv lists. Here I mean message in the SMTP sense. As I understand it listserv splits list messages into seperate smtp messages with some alrogithm that has a configurable max number of recipients per smtp message. I have: MAXBSMTP=100 in my go.user file. Would I be correct in assuming this is the maximum number of recipients that will be that will _ever_ be for a single SMTP transaction? In other words if I have 300 users on a machine recieving the same listserv message, then it will arrive in at least three SMTP transactions? -John Sheehy University of Florida
