Exchange 2010 Can't Receive Email

I recently installed Exchange 2010(all roles on one server) on a 2008 R2 server.  Upon initial install, I was able to bind to port 25 and issue:

helo
mail from:<some external email>

and receive Sendor OK.  I also, via static DNS entries, send and received email just fine.  Now, 3 days later when I am ready to change the DNS, no matter what from recipient I use I get the following error from the exchange smtp service:

530 5.7.1 Client was not authenticated

Undoubtedly, it will be recommended I make sure Anonymous is checked on the inbound receive connector.  It is definitely checked.

This is on a Vsphere ESX server with all the appropriate specs outlined by Microsoft on the virtual server.

The firewall is a Cisco ASA 5505 and I have disabled any SMTP inspection.  The firewall is plugged directly into the same L3 core switch the ESX server is, and there is no ACL or upper layer protocol voodoo enabled.

I have poured through as much documentation and forums as I can, and I can't seem to find anyone else with this issue if they have Anonymous checked.

Any help would be greatly appreciated as I simply can't figure it out!!!

Open ESM -> server config -> Hub transport

find your server and select it then in the lower hand side look for the "DEFAULT receive connector"

double click on it go to permission tab and check anonymous

done
coderccCommented:
Actually check ALL the connectors under server coniguration > hub transport > receive connectors, not just the default one and allow anonymous access. You might be surprized by which one of the receive connectors actually is active here!

Do NOT touch any other connector other than the Default one. if you configuration is not messed up with no need to mess it up yourself

just edit the Default receive connector again DO NOT change the client connector

Anonymous is definitely checked on the default connector.
AkhaterCommented:
If anonymous is checked there is no way to get "530 5.7.1 Client was not authenticated"

please run get-receiveconnector | fl from powershell and give us the results

I totally agree with you which is why it perplexed me enough to post here.  Here is the output of that command for the Default receive connector, as you can see AnonymousUsers group is added:

Are there any other receive connectors defined exepct the Default and the client connector?
We had a case where a client had a special receive connector defined for a fax appliance but that one (instead of the default connector) actually took all the traffic and needed to have anonymous to be checked.

Remarkable!

I have a receive connector for our Kaseya server to send mail out.  It is restricted to that specific IP address and it never even crossed my mind to check this!!!

I am truly appreciative for your insight on this as it was driving me crazy.  

I have done many 2003 and 2007 installs, and this is my second 2010 install and just never thought about this.

Thank you!!!
