    Exchange - Incoming SMTP

    I'm just in the throws of setting up our new Exchange box - I've setup so that OWA works correctly which is fine but I've got an issue with SMTP.

    When I change on our ISA where incoming mail is sent to 10.2.0.6 to 10.2.0.7 nothing comes through - As soon as you change back it works - I'm pretty sure I have set it up correctly but apparently not - any ideas folks? Most probably dead simple i'm just being an idiot!

    have you examined the mail queues in exchange to see if any traffic is coming in? It sounds like an ISA problem? Turn on logging on the ISA box, if it is denied connections it should show you .... was good when I was examining some issues we had

    Just some thoughts

    Its not getting to exchange - i'll look at Isa just can't see much valid info - Its getting to ISA its just ISA cannot forward for some reason.

    1. Are you using publishing rules for SMTP?
    2. Up the receive connector logging on 2007 and see what the logs say

    Publishing rules on the ISA? if so yes - its setup and working on there as it works when i point to original server - when i point to new one it doesn't come though

    Where is the receive connector logging? Toolbox?

    Unlikely you have missed this, but is ISA the default gateway for the exchange box? It is possible to set up a forward that can't be replied to because the host you are forwarding to tries to send replies to a different gateway.

    Have you tried telneting to port 25 on the ISA externally, see what (if any) answer you get?

    So the new rule for the new server is identical except an IP change?

    Go to the EMC>Server Configuration>Receive Connectors and turn up the logging on the appropiate connector.

    I assume you have the default 2 unlesss you have created additional connectors. If not do it on the Default connector.

    From the ISA server, can you telnet to the new Exch server on port 25?

    @tom_newton - the default gateway is our core switch which then routes to the ISA (as vlans) - this is the same on both so shouldn't be a routing problem (I hope!)

    @sukh - will turn on logging and test this evening - not sure I can get away with testing during the day!

    Sure, sorry, the testing I'm saying is just a telnet test from the ISA to the new Exch server via a CMD prompt. This is just to verify that a connection and email can be sent from the ISA to Exch.

    Oh ok, there's no impact and you dont have to restart any services if you worried about an outage. You can do this on the fly.

    Yeah thats cool - both Telnet and Tracert are correct so its def a problem with Exchange. Will play around tonight with the Receive connector and logging.
