Exim not Listening on port 465 or 587 for TLS connection

eximsmtpsmtp-authubuntu-14.04ufw

I am configuring Exim on a Ubuntu server to send and receive mails via TLS.

Followed many guides which shows on how to configure Exim with TLS but still my Exim doesn't listen on 465 or 587

Exim only listen's on port 25 and I am able to send an receive mails

This is the official guide that I followed:
https://help.ubuntu.com/community/Exim4

But still no luck, also I cannot find any reference in the config files which indicates on which ports is exim listening

I have also allowed the ports 465 and 587 via ufw using the command:

ufw allow 465
ufw allow 465

but still Exim won't listen on 465 or 587, can anybody help me on why this is happening or is there are steps that I am missing

For Ubuntu 18.04 I've found that the following works in update-exim4.conf.conf:

dc_local_interfaces='<; [0.0.0.0]:465; [0.0.0.0]:587'

Then the usual: run update-exim4.conf and restart the service.

Check (sorry - there are more modern ways, but fingers remember netstat):

# netstat --listen -lnp | grep exim
tcp        0      0 0.0.0.0:465             0.0.0.0:*               LISTEN      10874/exim4         
tcp        0      0 0.0.0.0:587             0.0.0.0:*               LISTEN      10874/exim4

NB: It may be good idea to enable port 25 as well. For example, some local services may want to send mail to localhost:25.
