How to run two mailcow containers?

Is it possible to run two mailcow containers that have different volume directories on Centos 7? How can this be done?

Why would you do this?

esackbauer I will use the first mailcow for a small number of mail accounts (about 500) my main emails will be there, and the second for a large number (about 50,000). This is because I have to wait a very long time for the admin panel to load. I’m also going to use different domains for both mailcow

different domains you can handle also with one mailcow installation.
But I doubt dockerized mailcow will work for 50000 users with one installation. Did you check the system requirements for SOGo, Solr, ClamAV and dovecot for that many mailboxes?

As much as I’m in love with Mailcow, 50.000 account on a single server instance is suicide, from every single perspective, every component is going to be a bottleneck.
While you might be able to run two instances side to side, you need a way more distributed architecture to be able to deal with 50.000 users (not to mention load balancing).
IMHO.
