Hello,

It means that it's something wrong with the e-mail account configuration. I suppose it's something related to that setting "Secure socket options (specify the SSL and/or TLS encryption)". The mentioned error means something like that "Forcing Non-SSL On An SSL Port". Please try to set the "Auto" value in Secure socket option", it's the safest way.
Best regards,
Patryk

Looks like configuration is wrong. Need to look again into.
If you need help, we may support you but that is paid support.

It may, depend on machine you have. The most easy way to check - disable task of sending emails and restart application.
