Exchange 2010 Gotcha - #2
Incoming e-mail CAN'T come in!
This issue is not exclusive to Exchange 2010 - it also exists in Exchange 2007.
The default receive connector created by the Exchange setup process does not include permissions to include "Anonymous users" on the default server permission group. Microsoft assumes that you will be using their Edge Server product (which isn't Anonymous, but Authenticated).
Of course, most people (? - at least my customers!) will not be using the Microsft Edge Server product, but some other gateway e-mail product.
Therefore, you will need to set the "Anonymous users" permission on the default server permission group.
Otherwise - incoming Internet e-mail will bounce!
Until next time...
If there are things you would like to see written about, please let me know.
[Edit on April 15, 2010 to spell "Authenticated" correctly.]
