I have a new Virtualmin installation, Centos 7 on AWS. The host is named mailx.somedomain.com , My IP is unrestricted, reverse DNS is verified. I added somedomain.com as a virtual server so I Can get email and have website for it. The website will be at www.somedomain.com not mailx…
I also added anotherdomain.com so I can host email. I login to usermin for my account at anotherdomain.com and I can send email out to gmail, but I cannot reply back. Log indicates TLS problem as reply does not show up Usermin.
Sounds like TLS is problem. What is best way to get TLS enabled on Postfix (assuming since mailx.somedomain.com is the server, that is the host that needs the certificate). Do I just do a self signed or do I purchase one somewhere and then install it into Virtualmin?
