Can send but not recieve e-mail

[cjackson]

This has me puzzled but I'm sure their is an easy answer...

I have 4 Exchange 5.5 servers, 2 at my main location and 2 at remote sights.

I can send email OK (internal and external)
I recieve internal mail OK from sights that do NOT have a remote Exchange server.
I can not recieve any external mail.

This has all worked fine previously.

I have reinstalled Exchange and ran isinteg -patch on the main server (this was the only way I could get anything to work at all) but have not done this on the other servers.

Any suggestetion or advice would be greatly appreciated.

Thanks Chris

Where is your internet mail service installed?
How are your sites organized?
Do you have 1 exchange site with 2 servers and 2 sites with one?
How is your domain structure?

Did you have the problem before or after the reïnstallation?

Regards
David

David,

The two Exchange servers at the main site are set up as two sites, one of which is acting as the internet mail server. The servers at the remote sites are set up up as another two sites (I know its a bit weird it happened as a result of moving servers from one place to another).

There is one domain.

This setup has worked previously, however the reinstall was necesary because i had many problems - could not send or recieve anywhere before the reinstall.

Thanks in advance for any help

Chris,

I would make for sure your DNS Host's MX records for your company are correct and pointing e-mail bound for your Internet domain to the correct Exchange Server IP (the one with IMS and MTA running).

If you can't receive, my first instinct is to check that. Exchange's IMS will do its job (presuming that your user accounts do have the appropriate SMTP address inputed) if you haven't "customized" (i.e. messed) with it too much.

Good Luck...

Are you running Proxy server? I've run into an issue when we updated service packs, SMTP was block by Proxy. Had to shut both Proxy and SMTP services down and restart SMTP then Proxy. Had to reinstall the Proxy server.
