[kwlug-disc] Testing a mail port

[Joe Wennechuk]

Hello All,
I am helping a customer, the issue is they can receive mail IMAP, but can not send. When I call the people at the domain they say outgoing smtp is port 25, or 587, and incoming IMAP is 993. They also have POP on 110 , and Webmail on port 80, and some other services. I can not contact the mail server on either 25, or 587. I have tried to use nmap to find the open ports. When I call Bell they instruct me how to open a port on the router; they are not understanding me. I have seen Bell block port 25 before on home accounts but not 587. What should I use to test this? How can I prove it is Bell blocking it? I have been testing the listed ones with telnet which I think should test correctly, and all ports listed by nmap respond, but 25, and 587 give no response. I have pasted some of my other tests below.
nmap results..joe at streetposts:~$ sudo nmap -Pn mail.ufn.com
