Exchange 2013 Server does not support secure SSL or TLS connections externally
I need to setup external email sending capability for a web-site campaign but I can't get emails to send using TLS or SSL, from an external location over the internet as the server responds with "Server does not support secure connections".
I'm not sure if it's SSL certificate configuration related or firewall related.
The reason I'm suggesting it could be SSL certificate related, is because if I test internally, using the external SMPT server address which resolves internally (e.g. mail.companyname.com), it responds with "The remote certificate is invalid according to the validation procedure.".
However, if I change the SMPT server to match the actual LAN hostname of the Exchange Server (e.g. EXSVR01.companyname.com) then emails are sent successfully using TLS or SSL.
The SSL certificate is a signed certificate from a certificate authority.
