I'm using Exim and all internal email is getting stuck in the queue. I'm seeing the following error in my Exim log: Failed to find user "system" from expanded string "${lookup{$domain}lsearch* {/etc/userdomains}{$value}}" for the central_filter router. How do I resolve this?

To resolve this issue, do the following:

Edit your /etc/userdomains - find the domain in question.

The correct entry for this domain is:

your_domain.com: youruser


your_domain.com: system
