Run this on your own machine — store install isn’t on yet.Copy
A complete mail server, and an honest account of the rest
Postfix, Dovecot, Rspamd, ClamAV, SOGo webmail and mailcow's admin UI as one stack — with the DNS work no installer can do for you written down before you start rather than after you fail.
What the SHC package gives you
Eighteen services, one command
The part it cannot do is written down
Mail needs MX, SPF, DKIM and DMARC records on your mail domain, and nothing automates them
Most clouds block port 25
It becomes the estate's mail relay
Install publishes an SMTP integration and the mailbox behind it
