Question : Undeliverable Email with Exchange 2007
A while back we upgraded from Exchange 2003 SBS to Exchange 2007. During the misery we discovered that besides the two versions being incompatible, there is a address problem which we cannot resolve on our customers end. We get a lot of undeliverable because of the "First Administrative Group" in the addresses of some of the emails.
IMCEAEX_O=MYD_OU=First+20a
dministrat
ive+20grou
p_cn=Recip
ients_cn=a
mar@mydoma
in.com #550 5.1.1 RESOLVER.ADR.ExRecipNotFou
nd; not found ##
The problem is that
[email protected]
is a valid email address. How do I tell exchange that addresses that come in with "First Administrative Group" are ok and actually should go to the Recipients_cn if valid, which in this case it is.
Thanks.
