Using comcast business class's SMTP server as a smarthost for Exim4 in Debian
I used to be able to use
smtp.comcast.net
as my SMTP server (by setting dc_smarthost='smtp.comcast.net'
in /etc/exim4/update-exim4.conf.conf
and running sudo update-exim4.conf), but this is no longer possible. I now have to use the SMTP server specified in for my account in the comcast business site (followed by ::587
) along with authentication and TLS encryption (by adding my comcast credentials to /etc/exim4/passwd.client
and MAIN_TLS_ENABLE = true
to
/etc/exim4/exim4.conf.localmacros
). All this is well and good, and I consider it in an upgrade, but for some reason, Exim4+GnuTLS simply could not get along with comcast's TLS implementation.( Collapse )
