Eric, thanks for reassurance ! Did I dream the "command count" rejection also - I'm sure I saw it when someone missent a posting to LISTSERV - noted it because it did NOT say "Error count exceeded" as expected - I had thought the item I saw was considerably less than the 2700 figure mentioned by <?> earlier but I'm NOT sure of that. ( I don't believe the item was processed at all - simply bounced immediately to listserv maint based on size ?? ) If such a mechanism already exists, that may be a possible solution - drop limit way down unless item from a NAD listowner and/or REQUIRE confirmation from sender and/or listserv maint for files over limit - mike
