Very Sad Request

Look I'm really sorry about this but I have a small PC problem that is driving me round the bend and I'm looking for some help.

If you meet the following criteria then I'd really appreciate an Email to Mark@ecc-limited.nildram.co.uk

1) Are you a geek and a MCSE or even a MVP

2) Know about Exchange / STMP and how they communicate

3) Know the difference between an MX and a A record

4) Perhaps even ISA

5) And if the above isn't enough, what about SBS 2003 / DNS and IIS



If you solve my problem I'll marry you, anything half way I'll buy you a beer !



Cheers

Mark

Is the problem sending, receiving, or both?

Sending is fine, internal domain and external.

I can Email, from another site, the domain and can see in the router log the SMTP request. A Network Trace shows the NIC with a source IP of the Email sender and it doing some SMTP stuff.

But I don't see the SMTP server receiving the Email nor Exchange getting it.

Could be the FireWall or even Exchange but I'm lost. Not really my area of expertise although I'm learning fast.

I have a MS paper on SMTP and Exchange to read ( 285 pages ) which seems the dogs but am 90% sure this is something very simple and a MCSE / MVP would laugh at my ignorance.

I'd be happy with that !

Mark

Are you sure that the connection's SMTP? What's the Exchange server "talking" to?

Assuming your talking about ecc-limited.com..

The MX record points to big-blue.ecc-limited.com (213.208.109.172). I can't access it via telnet on port 25 - are you sure that port 25 is open?


Note: Anything in your router log from 81.86.25.158 is me

Well I can't be 100% sure but I can Telnet internally to port 25 and it is sending mail internally and externally.


Looking at the SMTP server it appears to listen to "All Unassigned" IP addresses which should cover my LAN and Internet NIC. But if I expand the list of possible IP addresses to listen on then it only has the LAN IP address. I would have suspected it would have both in there ?

Looking at my router I don't see your IP address which is unusual?

Thanks Mark..
