XF 2.2 Issues with email


Well-known member
I've recently upgraded to the latest and greatest version of XF. Not sure what has changed, but I'm getting the following errors in regards to emails.

(I haven't changed any of the settings)

No idea what to do. I'm unable to send any test emails.
This is because of blocked TLS v1 , TLS v1.1. protocols . In WHM go to EXIM configuration manager and Allow weak SSL/TLS ciphers” from “Off” to “On” and Options for open ssl keep "+no_sslv2 +no_sslv3" . It is not recommended using weak ciphers , but still if you want to use it go ahead !
