Been doing my own delivery for 6-8 years. This is the first

The laptop varies between 5 ISPs:
Comcast
Road Runner
Optimum Online
Office/(XO)
NetAccess
The server sits on Verio/NAC.

Don't think thats the issue. I'm the first to bitch if there are
DNS issues at the place I'm at, my systems I get into aren't forgiving.

Forward/reverse should always work (My systems won't let me get to
them if they don't)

With the laptop I can see that maybe as an issue, but why from
the server?

Ok, maybe, but then why can I telnet 25 without an issue. Isn't this
what the machine does anyway, establishes a connection to 25?

I think its the most recent in the 8.12 train.

My laptop goes so many different places, I can't keep it similar with
where I am all the time. Wallstreet34 is a NAT, there are actually 1/2 a dozen
of us behind it. But a TCPDUMP of 587 and 25 show it not even TRYING to
make a connection.

I send out a few dozen emails a day. The ONLY other place I
have a problem is Paul Vixie when I'm at kickstartusa.com because its
on RBL. Otherwise, NEVER besides ones that go to that host. AND IT DOESN'T
EVEN CONNECT TO PORT 25/587
So why does the other IP (The server) have issues too? What can you
say about that one? (vjofn.ttsg.com)
Below is the TCPDUMP, last 2 are after its failed are a ping of
another system.
himinbjorg# tcpdump -s 4096 -X -n
