Hi,
I’m a new Delta-Chat user, wanting to self host chatmail on my own. Is it possible to change the used ports? I’m running already a mail server (postfix+dovecot) on the same machine.
Thanks!
The deployment of a DC relay using the official chatmail code takes over the machine; it will install a custom Dovecot DEB for example (patched to include a feature not in upstream), alter your repos and basically reconfigure everything from /etc/resolv.conf on down to installed packages. You do not want to deploy the current chatmail infra on an existing mail server, it will create a disaster of your existing setup.
A basic VPS (5-10 USD/Euro range) is plenty to run a relay for a whole bunch of users, I found my best deal this past cycle at OVH fwiw, 4cpu/8ram/75disk for ~$8 USD/mo (for a year). If you can snag one, demand has been high in their Quebec datacenter(s) for example so you can’t always get one when you want.
Well, there is a docker installation, but it seems like changing ports is not supported
