good day,
I am having problem with my ISP. I can't seem to send outbound mail (SMTP) when I do a telnet to my smtp server i get a "connection closed" error. meaning they might have closed my port. But according to my ISP, they did not do such thing and that the mailserver's port is open.
Is there a way for me to check if the SMTP is open or not?
please advice. thanks
Nate
