Telnet by default is on port 23, but SMTP is on port 25, so the command you
would want is "telnet jacklinks.info 25" - I have tested that command and
established a connection from my server.

Okay i have configured ISA 2004 to allow ICMP but i still cant use the
tracert command. If I Telnet jacklinks.info i get a message "Could not
open the connection to the host, on port 23: connection failed.

Have absolutely no idea whats going wrong.

To get through the gateway, I would assume you need to change rules on
your
firewall? tracert uses ICMP which a lot of companies block.

Can you telnet on port 25 to their server manually? and then run through
the
smtp commands http://www.yuki-onna.co.uk/email/smtp.html that should
give
you an idea as to where the problem lies.

I do not get an NDR back. I have got a message stating that the
sending has been delayed but it does state that the message will still
be sent however it never does reach the recipient.

The strange thing is i have always been able to send to this domain,
its just recently that this has started to happen. There have been no
configuration changes from my side.

How would you suggest i get through my gateway?

My first thought would be that tracert is being blocked at your
gateway -
hence you cannot tracert to any domain.

Do you get an NDR when sending to the problematic domain?

Whilst the other side can say "we receive mail from everyone else" you
can
probably say "we are able to send mail to everyone else". We had the
same
issue about 6 months ago - turned out to be a misconfiguration at the
receipients hosting company.

Hi Guys, please if anyone can help it would be greatly appreciated.
I
am having a problem with sending emails to an individual domain.
All
other domains i send to reach the recipients.

Now i know the first thing that people will say is that it must be
something on their end. Thats what i said too but, they too recieve
mail from everybody except us. The domain i am trying to sent to is
jacklinks.info and my domain is cms-mail.net

I have found out who hosts their domain and its a company called
all-inkl.com. I do a tracert from my SBS2003 server that has
exchange
running on it.

First hop resolves my I.P Address.
All other 29 hops give a request time out.

The strange thing is if i do a tracert to another email doman it
does
the same thing but i know that the recipient will recieve the mail
if i
send it.

My questions are:

A) Why does tracert not work for any of the email domains i am
trynig
to route to?

B) Why are my emails reaching all other domains except the
jacklinks.info domain?

Thanks you in advance for any help.

Kind Regards

Colin Sadler
