i have two exchange 2003 questions
first - i have a problem where if someone sends to person@domainA.com they get a undeliverable saying that their message couldn't be delivered to person@domainB.com
is this a DNS thing, or would something in exchange be sending emails directed to domainA.com to domainB.com?
also, in the relay section, if i try checking "allow authenticated users regardless of list above"
is the change immediate, or is there a lag to propagate the changes?

As for question 1: This can happen if person@domainA.com has a redirection to person@domainB.com and person@domainB.com has some restriction or has been deleted.
Question 2 (which you realy should post seperately!): Not sure, but restarting the transport service will definately activate the change in any case. This can usually be done safely during production hours. Small risk is that when there's a problem and the service won't start, users wouldn't be able to sent/receive mail. I don't know the stability of your environment, so I can't estimate this risk...

Full name is MSExchange Transport Service. It should be there...
I'm not saying these are trusted sites. It could be that one user forwards their mail to for instance a hotmail address. Does the issue occur to all users in domaina.com?

The curse of the end user strikes again      

You’ve updated all your end user’s email signatures. Hooray! But guess what? They’re playing around with the HTML, adding stupid taglines and ruining the imagery. Find out how you can save your signatures from end users today.
