How do i unblock the port 25 in my mac firewall? I cannot use my mail client such Mail or Entourage. I did
telnet mailserver 25 and got "connection refused".
On the other hand, I can receive mail because the incoming mail port 993 is opened, I did
telnet mailserver 993 and was able to get through.
I can use Outlook on my Windows to send mail.
So I reckon the port 25 must have been blocked by my mac.
