This is an odd problem that may or may not be Mutt related. I'd be glad to continue the discussion by private basis if appropriate. When I attach a gif file to a short message, the 'send' fails. I've gotten failures with gifs of 26 kb and 7kb, yet a gif of 1.9 kb is sent OK. More puzzling still, if I attach text or html files of 7 - 30 kb rather than gifs, they are sent without error. I use smail to send to my ISP as smart host, but I get the same behavior from sstmp. Inspection of an smail debug log for a failure reveals that the failure is apparently due to a lack of an acknowledgement by the smart host when my MTA sends a single "." to show "end-of-data": [locking info, message ID, transport driver, etc deleted for brevity] SMTP-reply: 220 uz.ComCAT.COM ESMTP Sendmail 8.9.3/8.9.3/sol2/mh/19991004; Mon, 27 Mar 2000 15:03:14 -0500 (EST) SMTP-send: HELO localhost SMTP-reply: 250 uz.ComCAT.COM Hello a589.ComCAT.COM [209.116.188.89], pleased to meet you SMTP-send: MAIL FROM:<hlarons@localhost> SMTP-reply: 250 <hlarons@localhost>...

[here's where things stop. There is NO "SMTP-reply: 250 Message accepted..." from the smart host, and I need to kill smail or the box just sits there. I've tried "unset set allow_8bit" but that makes no difference. Any ideas, anyone, please? Howard Arons -- Powered by SuSE Linux 6.3 -- Kernel 2.2.13 Communications by Mutt 1.0i
