Hello there everyone!
I have a server whose box name is like this mail.boxname.com. I have successfully installed the Let’s Encrypt Certificate for that domain.
If I don’t want to move full control of DNS for these other domains to mail.boxname.com, will the emails still be secured by TLS/SSL? I’m assuming that they will since any SMTP client will be connecting to the box’s hostname instead of @otherdomain.com.
Thank you in advance.
Yes. The secure connection is with mail.boxname.com, not the individual domains.
Thank you for clarifying.
Not always true, if your MIAB server both hosts email AND web, you can use:
When I was hosting with MIAB that’s what I would tell clients:
“Use domain.com as SMTP, IMAP and WEB” The only thing here is that you will ALWAYS need box.miabdomain.com/cloud for NextCloud.
domain1.com/webmail will also work.
This all stems from MIAB server hosting both email and WEB though.
