Re: message stored in Sent folder even if sending fails

[web626]

If sendmail fails user is notified and I think there are many options to
save the message. For example if I press q I can postpone the message.
 
If mutt is used in script and sendmail fails, then non-zero exit status
is sufficient. Script should do whatever is needed and mutt does not
need to trash mail folders with crap.
 
IIRC other email client keeps a queue in "Outbox" folder and if sent
successfully it is moved to "Sent"
