I want to be able to send email from mutt through an SSH tunnel I can SSH into the SMTP server, but I don't know how to tell mutt how to use the tunnel to send e-mail.
Can someone help me out, please?

Using remote SMTP is described here: https://gitlab.com/muttmua/mutt/-/wikis/MuttFaq/Sendmail
So with the tunnel you'd set up your SMTP to localhost, but with the tunnel port. Eg. you create tunnel 8025->25 on remote:
ssh -L8025:smtp.example.com:25 serv.example.com
And in Mutt configuration (.muttrc) you put:
set smtp_url="smtp://username@localhost:8025/"
BTW. Using remote POP/IMAP here: https://gitlab.com/muttmua/mutt/-/wikis/MuttFaq/RemoteFolder

good advice. I was wrong though, I didn't even need an SSH tunnel, just TLS. – devin May 11 '09 at 20:05

oh, you should have asked ;-) I've though that you're doing poor man's VPN ;-) – vartec May 11 '09 at 20:46

You don't need to have ssh with local port forwarding running on your own. Both mutt and Neomutt have config option tunnel.
tunnel
Type: string
Default: (empty)Setting this variable will cause mutt to open a pipe to a command instead of a raw socket. You may be able to use this to set up preauthenticated connections to your IMAP/POP3/SMTP server. Example:
set tunnel="ssh -q mailhost.net /usr/local/libexec/imapd"Note: For this example to work you must be able to log in to the remote machine without having to enter a password.
When set, Mutt uses the tunnel for all remote connections. Please see “account-hook” in the manual for how to use different tunnel commands per connection.
example:
neomutt -F /dev/null \
-e 'set tunnel="ssh host.example.com' \
test@example.com \
< /tmp/msg

It would be helpful to provide an example from the linked documentation instead of only the link. – Gerald Schneider Oct 05 '20 at 06:43

I just added minimal config example. Thanks for pointing this out. – Jakub Jindra Oct 05 '20 at 07:04
