My update-exim4.conf.conf file is (replacing <remote host name> with the actual name). If dc_smarthost has the port set to 26, mail gets sent. However with it set to 465, it stays in the mailq.

Any ideas?

What do the logs say?

Also, port 465 is SSL on connect, you probably need to tell exim that. (Or convince the remote server administrators do move to STARTTLS on port 587.)

I did add tls_on_connect_ports = 465 to exim4.conf.localmacros, which is supposed to cover the SSL on connect issue.

The log for an unsuccessful mail says:

I use /etc/email-addresses to change garydale to <sending e-mail address>. Otherwise the e-mail just bounces.

When I change to port 26 and leave everything else the same, the mail goes through.
