I will not stay with yahoo mail for much longer as they are really pushing me to "upgrade" to the new email version where you need to agree to have your email scanned for targeted advertising and for the three letter agency They invalidated the Search Inbox function and present me with the UPGRADE splash screen instead in last days I can set up IMAP mail and pull my 10+ years of email into Mail on my MB Air and then close the account Then, I would like to use my own domain email solution with 1&1 with the same email database, is this possible by just changing the mail server info ? (E.g. I would like go to mail Inbox and reply to an old email from my new email address). Of course, now I need to think about mail backup etc. Any recommendations how to handle this unevitable transition ?
