Some times when connecting to Webmail (Horde, SquirelMail, Roundcude) you may get the error :
"Failed to connect to localhost 25 SMTPFailed to connect socket Connection timed out code: -1response"When you find this error open the csf.conf file and search for the lines :
SMTP_BLOCK = “0″
SMTP_ALLOWLOCAL = “0″
And change it to
SMTP_BLOCK = “1″
SMTP_ALLOWLOCAL = “1″
and then restart the firewall
root@server
That’s all you are done.
