How can I auth a tls certificate for an smtp server without using http?
Currently I am using getssl bash script.
The server that requires a certificate is firewalled off only port 25 is available!
DNS authentication is off the cards this is an enterprise and therefore changes must go through a time consuming (and costly) change management process.
I can shut down the smtp server while authentication occurs but auth must occur over port 25 not 80 or 443. This would be impossible on the firewall.
How can I implement this?
