There's a difference in behavior between LISTSERV and NETSERV with regard to sending files. Our prefered file format is set to PRINT. NETSERV by default will send unencoded files with lines up to 132 characters in length. Beyond that, it switches to LISTSERV-Punch format. LISTSERV behaves in a similar way, except that it makes the switch at 80 characters per line, rather than 132. That's would be reasonable if the prefered format were PUNCH, but since it's PRINT it seems to me that NETSERV's behavior makes more sense. At least I've never heard of a system that could not handle PRINT files with lines up to 132 characters.
