Greetings-
     We have a web server hosted at an offsite location.  That system uses SMTP to send messages out to customers, ect.  I received a bounc back from the server saying that it couldtn reach "MY" inside sales team.  (See below)  I now the account is there and valid.  I even double checked it.  So what gives?  Any clues?  Thanks!

Are you able to send an email internally to nsidesales@domain.com? Is this mailbox/user  live?

Check the Exchange General tab on the group properties and make sure that there are no restrictions as to who the group can accept mail from.

Yes, we are able to internally send email to insidesales@ from inside and from outside.  The message is being sent from our webserver which is hosted externally.

I checked to be sure and there are not restrictions on who can send the group email.  

Thanks!

That isn't an Exchange message. It is being rejected by something else.
Does the server keep SMTP logs? If so you need to see what it was connecting to,

Ok, both my internal Exchage Server & my External SMTP server have logging enabled.  However I am unsure how to find the SMTP record that corrisponds with the message above.  I am searching both servers now to see if I can find it by time stamp.

It depends on what you log, time stamp is going to be the closest, or at least get it down to a section of the logs. Hopefully it ha the IP address of the server it tried to connect to.
