Hi James,
well, best would probably be to ask tucsonwomenschorus.org what the reason is:
https://groups.google.com/forum/#!topic/demos.local.lists.cgp/U9x9iuYfdd8


But you could try a few things:
Here is an answer from support that I got a while ago. Hope that helps:

By default, CGP uses tsl1.0 for outgoing SMTP connection.
You can add "--SMTPOutgoingTLSVersion 2" starup parameter, so that CGP will use tsl 1.1 for outgoing SMTP connection.
Adding "!mx.target-mail-server.com" to the Send Encrypted (SSL/TLS) list at Settings->Mail.SMTP->Sending would tell CGP not to establish secure
connection when sending emails.
Obviously you should use a newer CGP version - there've been some TLS fixes and additions.

Well, we see tls problems raising.
I really hope that CGP will soon introduce a function "use plain if TLS does not work".

Regards
Ralf

Betreff: Correcting TLS error

Hello,
  CGPro 6.1.19
  linux 4.4.120-45-default x86_64

  CG could not send a message:
22:06:55.705 3 SMTP-000424(tucsonwomenschorus.org) failed to establish a secure connection with [216.222.193.110]:25. Error Code=TLS record version is not 3.x

  What does the error about TLS mean?
  What is the best way to correct it?
