SUMMARY: Sendmail problem on a Sparc 370

Date: Tue Jan 05 1993 - 22:48:21 CST

The general consensus to my problem. (Original query below) was that
if a mail message did not end with a new line character this would
happen. I'm including an old summary that was sent to me which explains

Much thanks to: (Tim Hoogasian)
