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

hi,

telnet is not a reliable mean to access mail. Ask them or install a decent software to view mails.

Hi Nate,

It seems like you are blocked off. When you telnet to your isp smtp server do you get any responce ? Typically the server should say something like 220 server ready etc. If you do not get any connection you are either a) blocked (being at rbl or similar) or b) your firewall may be configured so that only one ip from your network can connect with smtp.

Telnet standard port is 2*, however SMTP (default) port is 25.
here's an example connecting to the *rd yahoo int'l SMTP server.

open a dos command, type
telnet

then follow the following example that I used to send a short message to yahoo's post****** to wish him a good day..
you need to type exactly in the same format that I used.
note that, everytime you see a number preceeding the message, it means an SMTP server reply.
