IBMMAIL.COM is not a dial-in mail account service but a gateway to IBM's inter-enterprise network, which is mostly based on PROFS/OV. The 79 characters limitation is due to PROFS and IBM can't do much about it (unless you meant they *truncate* data past column 79 rather than folding it, in which case they definitely should fix it). I think the error message should be sent to the recipient rather than the sender. If the recipient feels this is a problem he can always contact the sender after the fact. If this is not possible, the following MAIL FROM: addresses should trigger the removal of the message: LISTSERV@* owner-*@* *-request@* Eric
