I can receive emails, just can't send them

Yesterday, all of the sudden, I cannot send emails at all. All 3 computers
on my network no longer send emails. I get the following error: 0x80042109.
I cannot telnet to my smtp server on port 25. What can I do to fix this?

If you cannot telnet into the mail server, and if you aren't getting
blocked by a firewall, then how do you know the SMTP server is actually
reachable and actually running? Can you do a traceroute to the SMTP
host? Can you ping that host (they may have pinging disabled)?
Reaching the host and it responding to a ping does NOT mean the mail
server program that is supposed to be running on that [boundary] host is
actually running and responsive. Have you called the e-mail provider to
determine that their SMTP server is okay?
