I don't believe it's possible directly with Mutt configuration, but if you send via sendmail (instead of SMTP), you can do that with the sendmail command instead, replacing it with a script that checks the email it's about to send, and aborts with a message if it has an empty Subject: line. I have a similar script that, among other things, checks that I actually have attachments when I have "attach" or "patch" in my body text. If you send via SMTP, I don't think you can hook into send like that. You could change your editor to a script that 1) calls the real editor then 2) checks for an empty Subject:. That would not prevent you from removing it in Mutt compose window afterward, though. -- Ed Blackman
