Just upgraded to SM15. Created mild havoc with my settings, but things are stable(ish) now. Seems like half my settings got moved over in the upgrade, half did not.
Except...I now get a PCI fail on Port 25. This is secured using TLS, but the scanner is reporting "Plaintext communication is allowed without a TLS connection". AUTH_LOGIN is disabled...cert checks out okay...any other ideas? Things worked fine with SM14, I am hoping a bug has not crept in.
