Yea, but it is more than that. If I just send a test message to myself, it
just goes. A few minutes later it comes back in just fine. If I send to
one of these other places, it INSTANTLY gets this 550 error in my inbox. If
I then change from using mail.colbyconsulting.com as the smtp server address
to the "local" smtp address (RR address) it goes out just fine. So it is
not a case of "we don't like this destination". It is just forcing me to
send through their mail server, but NOT when sending to my own mail server.
Truly odd don't you think?

It depends on how they have THEIR mail server setup. With the onslaught of
spam, a lot of mail servers get down right finicky on what it will let
through. I know my personal domain is/was blocked on several mail servers
because the IP's in my domain were listed as dynamic, instead of static,
which they WERE static. If the domain of the email you are sending 'from'
doesn't match the IP's sending the mail, that's another big 'block'. Then
there are several 'black lists' on the web, which store domains considered
to be spam.
Honestly, it's an issue that is a sore point for me (both spam, and the
methods used to block).

Does anyone understand what is going on with email sent from inside of
specific networks. Here's the situation...
I get the following error (as an example):
Your message did not reach some or all of the intended recipients.

using SMPT server mail.colbyconsulting.com. If I send mail to myself I do
not get this problem (to jwcolby at colbyconsulting.com). I have seen this
exact same symptom if sending from my client. It never happened before from
my sister-in-law's but is now.
It turns out that if I look at her email smtp server
(mail.rochester.rr.com), and modify my smtp server to match it works. It
appears that this is the classic port 25 blocking thing. It is a royal PITA
to have to find out what the correct smtp server is, modify Outlook, and
send to that whenever I move from place to place.
At my previous host for MY WEB SITE, they had me set up to send on a
different port (26 maybe?) and then it worked regardless of where I was
since only port 25 was being blocked and my web email server
(mail.colbyconsulting.com) was expecting traffic on a different port.
The odd part here is that I can send to myself (always), i.e.
jwcolby at colbyconsulting.com. That must go on port 25 as well, so why does
that go just fine, but not the other message?
