To be more specific, I'm transitioning her from AOL to her own existing domain-specific address. Both are active. I did something similar before directing an AOL account to Google and switching the "Reply To" to a private Domain address until there were just a few stragglers who had the AOL address in their address books and then sent out a "closing acct, change your address book" notice after about two months. I thought if I could send her AOL mail directly into MacMail along with her existing private Domain address mail I could do the redirect in MacMail to cut off reply strings that hold onto the AOL adress and she could get her existing domain mail there too and do the transition without Google. Does anyone understand what I'm talking about? The last transition I did the place wanted to use Google as the final destination so all the mail could be online and everyone could pick it up from anywhere, this will be private and only picked up from the MBA.
