+:summary: Saving sent messages with Exim
+
+In shore.co.il I use the Exim mail transfer agent (SMTP server) along with the
+Dovecot IMAP server. Messages received in Exim are sent to Dovecot over LMTP. So
+far, pretty standard stuff. All of the configuration and setup can be seen in my
+`GitLab instance <https://www.shore.co.il/blog/ldap-auth/>`_.
+
+I wanted to save sent messages to a folder (like GMail does) but didn't find a
+way to do that over LMTP documented anywhere so here's what I did. I created a
+router in Exim that if the sender is one of the local domains (domains Exim
+receives messages for), then they're redirected to the LMTP transport but with
+``+Sent`` suffix attached so they're saved to the ``Sent`` folder. You can see
+the configuration `here
+<https://git.shore.co.il/shore/mail-docker/-/blob/master/exim4/exim4.conf#L665>`_.
