Hi,

I can receive messages that are being sent via the contact form on my webserver, as well as compose and send emails to external hosts, however; I cannot receive any emails that are being sent.

This is the error that I'm receiving in the logs:

Please post suggestions below, thanks.

Do you have MX records setup properly for your domain ?

secondly
you may want to enable lookup for local domains in your Exim

Code: Select all

nano /etc/exim4/exim4.conf.template

goto line that says

Code: Select all

dnslookup:
		  driver = dnslookup
		  domains = *
		  domains = !+local_domains
		  transport = remote_smtp
		  no_more

change domains = !+local_domains to domains = *

Finally Test how exim will route a given address

Code: Select all

exim -bt <email ID>
