LetsEncrypt - Axigen Webmail on same machine as Apache Webserver

Hi all,

I have Apache running on RedHat (RHEL) v9.3 with a number of VirtualHosts.
Certbot runs very successfully renewing a bunch of LetsEncrypt (LE) certs for the VirtualHosts.
LetsEncrypt (LE) requires access to the Apache webserver on ports 80 and 443 to renew its certificates.

Axigen (v10.5.15) is also installed on the same RHEL machine.

Problem: Axigen WebMail cannot use ports 80 and 443 while Apache is running and using these ports. This means Axigen cannot create and auto-renew LE certificates unless Apache is shutdown and Axigen WebMail is reconfigured for ports 80 and 443 (every 90-days).

Clearly not a workable situation.

Possible solutions (??):

Either Apache is configured so the VirtualHost “mail.mydomain” on incoming ports 80 and 443 directs to Axigen WebMail on ports (for example) 81 and 444 (… not sure how to do this), or

Axigen is configured to used the LE certs created ‘externally’ for Apache by Certbot. i.e. Axigen does not directly manage the LE certs.

Solutions, thoughts, recommendations (or a better way) gratefully received.
