I did an apt-get install mutt, which brought in exim.
In the Q&A setup, I told exim that I have a smarthost that relays my mail.
Except I typoed it. Plus, I need to specify a port.
So I see it saved it in the /etc/exim4/update-exim4.conf.conf file.
So, after I modify this file, is there anything I need to do to make it take affect, and where can I specify a non-standard port for this?
