all the mails sent using your server's smtp will need to authrize first with user/pass and it will allow only those users whose email address exists on local server.

all the mails sent using your server's smtp will need to authrize first with user/pass and it will allow only those users whose email address exists on local server.

cPanel/WHM enforces POP before SMTP authentication by default. With this authentication, if a user authenticates via POP3 then they are allowed to send mail for a period of up to 30 minutes without being prompted for SMTP authentication. If a user hasn't authenticated via POP3 prior to attempting SMTP, they will be prompted for SMTP authentication.

To always force SMTP authentication regardless of POP authentication, type the following command via SSH as root:

/usr/local/cpanel/bin/tailwatchd --disable=Cpanel::TailWatch::Antirelayd

Hi,

How do you undo this command line if you needed to, and put it back the way it was?
