Hi All,

It seems that the ISP blocking the port 25, therefore I have change them to port 587 by adding the setting.
587 inet n - n - - smtpd
on the maser.cf file.

With the same setting as below I'm still having problem to send my email using my my Outlook on the new port 587 although I have activated SPA (secure password authentication)
