We have Open SSL v1.2 installed due to security upgrades and shutting off insecure cipher suites and it appears that ListMail Pro cannot connect to SSH any longer as a result. I'm now getting the following error:

"TLS error on connection from [xxx.xxx.xxx.xxx]:48106 (SSL_accept): error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol"

We cannot send mail without authentication any longer so sending plaintext is not an option. Does ListMail not yet support Open SSL v1.2?

Hi,

Try preceding your SMTP hostname with tls:// or ssl://

If neither of those work a modification may need to be made to connect in a specific way or you could switch to PHP mail.
