Step 2: Check manualmx Configuration

In many cases, the error is related to the manualmx router configuration. Exim uses this configuration to determine how to route emails. To check if manualmx is causing the problem, use the following commands:

#nano /etc/manualmx

Find the line that specifies the configuration for the problematic domain, in this case, “domain.tld: host.domain.tld,” and delete it. Save the file.

Step 4: Restart Exim

After removing the manualmx configuration, restart the Exim service to apply the changes:

#systemctl restart exim
