Issue as seen here: MCE-923-53639
When customer trying to configure SMTP connection to remote server from their script, they will get timeout error because we have blocked it on our firewall end.
For example:
Could not access file: SMTP -> ERROR: Failed to connect to server: Connection timed out (110)
Solution:
#vi /etc/csf/csf.conf
Look for SMTP_ALLOWUSER
Then add the cpanel username into it. Something like below:
SMTP_ALLOWUSER = "advgeo,cpanel,shihaome"
After that restart csf
#csf -r
