You lost me on that one Chris. (mainly because we do not do forwarding
via CR ,but rules ..but that is another story...)

I send an email to [EMAIL PROTECTED] Email comes into the store and
then is forwarded back out to [EMAIL PROTECTED] via the IMC to aol.com. So
what you are saying is the message that goes from your exchange server
to [EMAIL PROTECTED] says it is from [EMAIL PROTECTED] (therefore SPF not
happy), rather than a message from [EMAIL PROTECTED] to [EMAIL PROTECTED]

Does that sound right?

cheers
Dean

It's not /you/ you have to worry about it's /everyone else/. Let's say I
have an employee who has a MessageOne e-mail address but receives his
mail at AOL. I create a CR in the GAL for [EMAIL PROTECTED] and add a
secondary address of [EMAIL PROTECTED] If one of your users e-mails
him AOL is going to check /your/ SPF record against /my/ forward. And
depending on how you've configured your SPF records, it may fail. 

So in order for forwarding not to break for your users, everyone else on
the planet has to upgrade their servers to be compliant with SPF
(regardless of whether or not they choose to implement SPF records of
their own). Since there's no announced patch or upgrade for currently
shipping version of Exchange, that presents a minor problem for anyone
who happens to be running our shared, but rather obscure mailer. Other
less obscure mailers have similar issues. 

Given the snail's pace at which many companies upgrade their mail
servers, the time until there's a significant number of mailers who
support this is pretty substantial.
