Subject:	SCOUG-Help: Sendmail Two

Content Type: text/plain

The short message is: the problem is solved!! The solution needs more work but the problem is now
known.

The long message is:

After the working sendmail at the SCOUG meeting I tried it at home and no joy. That means the
problem is with the hardware outside of my computer. I decided to start from scratch and reset the
router (pushing reset button) to its factory settings. From that point I set up all the
switches/parameters as they should be making sure the router was getting its IP from roadrunner's
DHCP server and that the DNS service IP was from roadrunner also.

FWIW, my hardware connections: cable --> cable modem --> Vonage VoIP (voice over IP) phone modem -->
Netgear router --> home LAN --> computers and printer.

The part that puzzled me was the IP for the router seemed OK but the IP for the DNS had a
nonroutable number. There seemed to be two possible sources for the error - the router wasn't
working properly or the VoIP phone modem was at fault. The easiest to check was the phone modem. I
took it out of the circuit (cable modem --> router) and everything worked. I got a better looking
DNS IP. Put it back and the same corrupt DNS IP was there. Took it out again and good IPs were
present. Sent an e-mail via sendmail and lots of joy!

It is interesting to note that SeaMonkey works with or without the VoIP modem in the loop. I guess
SeaMonkey, out of an abundance of caution, somehow directly supplies a good DNS server address.
But, as far as e-mailing and phone service, I can have phone service or the ability to send e-mails
but not both at the same time.

There are two solutions to my problem. A preferred one and one I really don't like unless someone
on this list mitigates my fears. The preferred solution is to get access into the Vonage modem and
tell it to pass all IP addresses through if it can do that. That will require Vonage allowing me
access. Which is not likely. Or perhaps they can/will do it. I'll contact Vonage on Tuesday to
see how far I get with modem access.

The less attractive solution is to place the phone modem on my LAN and have it work back through the
router to the cable modem. I'm not keen on having it inside a secured area though. Are my fears
well founded or not?
