Thanks!
I'm not sure I know enough to answer your question properly, but I will
try.
I'm running mutt on an Ubuntu OS workstation with sendmail installed.
I receive email using IMAP via a davmail process that in turn interacts
with Indiana University's Office 365 Exchange instance.
set spoolfile="{aarenson\@iu.edu@localhost:1143}INBOX"
I have the following in my .muttrc that I think were put in place to
deal with issues in _receiving_ email, but perhaps have a role in sending
email, too.
# For using TLS
set ssl_starttls=no
set ssl_force_tls=no
I don't see any obvious configurations that set how email is sent, so
my guess is that it is being send via sendmail on my Ubuntu workstation.
I have no record of configuring sendmail myself, and I kept fairly
copious notes when building this workstation in March, so I assume sendmail has
whatever is the stock configuration for its Ubuntu package.
