 Notice the MAIN_TLS_ENABLE = yes line is added and will this time, survive a service restart because of the localmacros file created above. Next, it is time to symlink your TLS certificate and keypair to the default location for exim4. In my case, I already had Let’s Encrypt set up on this server for my primary domain, so I just used that pair as follows (proceed with caution): Notice the MAIN_TLS_ENABLE = yes line is added and will this time, survive a service restart because of the localmacros file created above.
