I have setup my EX5.5 for my company. However, if someone sends out email to the users in my domain, it's going somewhere and I can't receive anything. If I setup a user for testing, I can send out email to people from the internet but can't receive.
Please give me some helps.
Thanks,

Do the DNS NS and MX records point to your new mail server. Might also be a routing restriction within EX5.5 but I would have expected the senders to reveive a bounce message.

many causes. as was mentioned above - you need to check your DNS zone for NS/A/MX records. other - firewall. is incoming connections permitted to your server from outer world. third - your ISP. It can lock or intercept traffic and route it itself some incorrectway. you didn't provide name of your domain so we can't check what's wrong - if you post it we'll see...

mx's dns record may be misconfigured.
Setup an NT machine directly to the internet, Verify that you can browse internet sites without problem (this will check for a correct DNS configuration)
Open a DOS box and start NSLOOKUP.EXE. This program will query internet DNS for your mx record.
Perform a query in order to check where mx record of yourdomain.com is pointing to.
The result (ip address) should be the same of your exchange server or firewall public's address.
