Help with ISP problem

[Al Hart]

My network provider and I are trying to work out a problem.

Try this for me:

telnet 66.17.141.96 587

Also, if someone would try it from a Mac it would be useful.

My ISP Provider says that when he does it it connects properly
(enter quit if telnet starts)

For me I always get an error.
(I have tried 4 different machines with 3 different network accesses)

C:\ARRIS93\lib>telnet 66.17.141.96 587
Connecting To 66.17.141.96...Could not open connection to the host, on port 587: Connect failed

(66.17.141.96 is the URL for mail.renderplus.com . 587 is an alternate SMTP port which they claim they have opened)

Could you also try:

telnet mail.estreet.net 587

(This is the ISP's email port. Which they can access and I cannot)

Thanks,

Al

Tavi,

Thanks for finding the on-line port scanner - I had been looking for one for hours last night.

However, when I use it, it fails:

@unknownuser said:

Scanning ports on 66.7.183.229

66.7.183.229 isn't responding on port 23 (telnet).
66.7.183.229 isn't responding on port 25 (smtp).
66.7.183.229 isn't responding on port 587 (submission).

And I was only able to use it three times.

I am able to ping the ip but telnet still tells me it is unable to connect.

I get a connection submission using the "T1" link you sent TBD so any ideas??

You should be able to telnet with port 25 though (which is the default email port)

Thanks to all who are trying this for me.
