I have HD-Sentinel configured to send me email notifications using a local mailserver. With HDS v5.50 this was working fine. After the Update to HDS v5.60 this handling broke, HDS now reports "Socket Error" upon sending (with the "test mail" function as well).
If I disable SSL/TLS/STARTTLS, sending again works without error.
I suspect the cause to be that I have entered an IP for a mail server, not a name. HDS can thus only check the server certificate for structural validity, but not for matching server name. Is such a check new in v5.60 vs. v5.50?
