Gentlemen,
i have Exchange2007 configured in DC..& in Exchange Server, send/recieve connectors are configured properly to get mails from outside..
we are using Linksys Wireless-N ADSL2+ Gateway Router for Internet..
the current scenario is that internal mails are working fine with all the users & all users are able to send mails outside very well...but from outside no one is able to recieve mail..
Default recieve connector is configured/selected with all permission groups except Partners...& there is one more connector configured as Client-Servername with only Exchangeusers & Exchange Servers are selected in Permission Groups...
but even though mails are not coming..
Could any one help me in this matter..
any help will be highly appreciated...
Thanks in Advance..

Here's the guide on how to configure Internet Mail Flow:
http://technet.microsoft.com/en-us/library/aa998212.aspx

Ensure that you have an MX record on your Public Internet accessible DNS servers for any domains that you wish to accept e-mail for from the Internet.

If this has all been done, check your Event Viewer for errors and post back any findings or lack thereof.

Verify how the linksys firewall is configured to port forward smtp/25 to the exchange server. confirm that its done and correct.
assuming its just one network/subnet from an external pc or using a laptop dialed up to the internet open "cmd" and type 'telnet exchange 25'. if you dont get something like "220 ESMTP xxxxxxxx". then check the security of the windows server/firewall to allow it
you could also use a shell account host, get a free one and test from there.
