Exchange 2003 - Problem getting mail from one customer

Problem getting mail from one customer but everybody else get through. The
customer uses an external mail distributor that runs mail systems for a lot
of companies. They claim that nobody else has reported a similar problem.
I administrate an exchange 2003 server for our company. This server stands
in the LAN and SMTP port 25 is ported through NAT to the server. The customer
has tried to telnet from his side with his PC and this goes OK. But when he
tries it from the server with telnet, he can’t get it through. He runs the
command "telnet domain.no 25. He then gets an answer after about 30 sec.
I have checked the logs and get the customers IP in my SMTP log and just the
quit command. An ordinary mail that goes through has EHLO, MAIL, RCPT and
QUIT instances in the log. I have also checked that it is no filtering that
stopping the messages and we don’t have any external filters. What could be
wrong?
Thanks in advance

Thanks for replay to my question.
Sorry about my finger trouble with spelling, English is not my native
language.

> Do they get an NDR?
No, after what I have understood they don’t get a NDR because the message
doesn’t get to our exchange server, it just goes to a QUIT command in SMTP.
There is no trace in exchange log, and in our SMTP log there is just this
post:
08:51:36 195.134.48.88 QUIT - 240

For a while ago I set up the tar pit feature with a value 5 sec. in the
registry, but I have changed this back to test if this is the problem, but it
wasn’t. It is now set back to 5 sec. again.

No problem. A lot of people who *do* speak English as their native language
use words like that as jargon like that; don't feel bad.  :)

Your domain has some DNS problems -

http://www.dnsreport.com/tools/dnsreport.ch?domain=ista.no

Your MX record is a CNAME - it must be an A record, not an alias. You need
to correct this in your public DNS.

You also have no reverse lookup record (PTR) for your public IP - contact
your ISP (whoever owns the IP/block) and have them correct it.

Not to be too picky, but "administrate" is most definately an *ENGLISH* word
which means "to administer".

ad·min·is·trate (d-mn-strt)
tr.v. ad·min·is·trat·ed, ad·min·is·trat·ing, ad·min·is·trates
To administer.

The American Heritage® Dictionary of the English Language, Fourth Edition

--------------------------------------------------------------------------------
administrate
Verb
[-trating, -trated] to manage an organization

Since I can't find the solution to my problem, I was reading post after
post... and just thought I should set the record straight on this one :Þ

Heh. Well, you're right - and I just looked it up, and it's apparently an
old construction. However, I like being a crank, so I'm sticking by my guns.
Anyway, I had a college English professor who dismissively referred to that
tome as "...the spurious American Heritage dictionary."  What about
commentator? Does a commentator commentate?

I'd think a commentator commented, but maybe that's because I'm a crank. <g>

well, back here in the old country an administrator administrates and a
priest administers. A commentator could commentate and comment: he/she would
commentate on the horserace but comment on the hats in the audience.

Administrate is a back formation from the word administration.
Dictionary.com says "administrate" is defined as "to administer".
