mutt smtp server support (no local mta)

Suppose you want to use a text-based mail client without having to install and setup a full-fledged mail-transfer agent (mta). Mutt from version 1.5 on, has support for your smtp
server (internet mta) on the internet.

All you need to do is recompile with the extra option --enable-smtp in ./configure.

See the last line of the following command:

# ...
./configure \
  --prefix=/usr \
  --mandir=/usr/man \
  --sysconfdir=/etc/mutt \
  --with-mailpath=/var/spool/mail \
  --enable-pop \
  --enable-imap \
  --with-ssl \
  --enable-locales-fix \
  --without-wc-funcs \
  --build=$ARCH-slackware-linux \
  --enable-smtp # <-- add this extra argument!
# ...

To configure the server you need to create a file called .muttrc in your $HOME and enter the following settings:

#openssl aes-256-cbc -in test.txt -out test.txt.enc # encrypt
#openssl enc -d -aes-256-cbc -in test.txt.enc       # decrypt
#echo "body" | mutt -s "subject" -F muttrc addressee@somewhere.com -a attachment
set smtp_url="smtp://smtp.server.tld"
set realname="Mutt Forevah"
set from="Who-ay-Em Ayemhoo"

Adapt to your smtp server settings accordingly.
