Yep, already openMake sure your site can perform outgoing connections on port 25. That is required for the functionality of the email validator, and the feature should NOT be turned on unless this has already been verified.
You can test this by logging into your server via SSH, then trying something liketelnet gmail.com
Bash:
# egrep '^TCP_|^TCP6_|^UDP_|^UDP6_' /etc/csf/csf.conf
TCP_IN = "20,21,789,25,53,80,110,143,161,443,465,587,993,995,1110,1186,1194,2202,11212,11213,11214,2112,22000,22001,2222,81,9000,9001,9418,10000,10500,10501,30001:50011"

Those errors begin only after I update addon to latest version (after I updated xenforo to 2.1)
