Hi,
I have a virtualmin installation on a VM host who provides 1 ip4 address and as many ip6 addresses as I care to configure.
I have around 6 domains configured with a virtualmin server per domain.
Each domain has to share an ip4 address and also has a unique ip6 address
I have Lets Encrypt SSL cert configured per Website for domains www.domain… and domain…
Currently the mail clients all use the same domain to send ( since I believe postfix doesn’t support multiple certs on a single ip4 i think?? )
The mail clients use a mail.theirowndomain… for receiving mail via pop or imap ( so via dovecot etc )
Just using the Virtualmin UI how can I make each dovecot user be served the cert for their mai.owndomain? ( possibly the same as their web domain one ).
My understanding is that if I use the Copy to Dovecot option within a specific virtual servers settings it just overwrites the global one used by dovecot ( is that right ?)
I think t would be preferable to use a cert per domain for all services for that domain but I dont think thats possible, so what are my options ( if any ) ?
Do I have to bite the bullet and make all clients use one mail server in the same domain ?
Thanks
