I just booked Sep 5-7 TPA-AUS for $250 on AA. I'll be there, but staying down
the road at a Hilton.
I'm landing at 12:40 on the 5th and leaving at 1pm on Sunday, it's all I could
fit into my schedule.
Anyone else coming?

Okay I have my network issues resolved. I had to implement policy
based routing to get things work consistently.
I was able to receive mail successfully too.
Onward and upward!
Actually what I said doesn't make any sense. I don't understand where
the problem is.
I'd still like to hear from anyone running a SMTP server on Linux, not NOS.
I was going to run a pipermail email list on a 44 IP. While I am sure
I can get it to work fine between other 44 hosts, my guess is that it
will see little use if I can't make it work like any other host on the
wide internet.
The latest problem again is with outside connectivity. There seems to
be some sort of TTL issue going on. My network /host isn't always
reachable from the internet. And it seems to depend on who you are
using for internet.
My host: 44.92.21.35
Seems to work fine from a time warner cable connection in Green Bay.
But other people report not being able to reach it.
Looking at other 44net hosts connected to the internet:
pinging 44.88.0.9 - Fine
pinging 44.4.92.50 yes but with packet loss
So it turns out a lot of my SMTP headaches track back to this bigger problem.
- Are you willing to establish an email server and be willing to maintain it?
- Who would be responsible for maintaining the accounts?
- Do you have a privacy policy in place?
- What is your ISP's bandwidth limit?
- Do you have the facilities to backup and store emails for all users?
- The same DNS entries would be required, and the ampr.org domain (or subdomain) would have to be the only one used.

Steve,
I have ran mail servers, but I do not currently run one on AMPRNet; my last attempt was to setup a home server was an IPv6-only server for the purposes of passing a certification exam. There are many reasons for not maintaining it (some of which may be why you're having issues, hope this helps):
- The domain you're using for email must have an MX record
- That MX record must point to a valid A Record (it doesn't have to be the same domain)
- Your mail server must be configured with the hostname name noted in the A Record
- The IP noted in the A record must have a PTR record that returns the same hostname in the A Record (this can only be done by one of our friendly Brians, this has to be done in 44.in-addr.arpa)
also make sure that
- you have configured the SMTP server to receive email for the domain in which you created a global MX record entry
- make sure that email account exists on the server
- if it is multi-homed, make sure the gateway/default route is over 44NET
While mail servers should work with the first two, many ISPs configure their servers only to "talk" with mail servers who also have the PTR record in place.

Thanks for the explanation Tim.
I haven't messed with running a mail server since 1999 so a lot has
apparently changed, and I am a bit concerned about doing it right.
Presently I am trying trying exim on a CentOS platform. It seems to
send out mail just fine, but when it comes to answering someone else
connecting to it from the general internet that is were I apparently
don't have something configured right yet.
Anyone care to create a nice write up :-)
I found that Comcast only blocks "Residential" subscribers from port 25.
The minute I upgraded to a "Commercial" account, all restrictions were removed.
The best part was that for a commercial account with one dedicated IP
address, it was cheaper than the residential service was.
Not sure this approach will work for all though.

What ISP are you using. Most do block outbound 25. ATT will unblock if you get the right person on the phone.
