Wow. Signed up about a month ago. Switched all of my banking and other important items that require email to this new email address - only to find out that they just randomly, without explanation blocked it! Stay away - seems like I'm just another one in a looooong line of people this is happening to. Could it be bc I didn't want to give them an alternate email they could sell? Or that after a month I refused to sign up for their premium service? Shame on you, mail.com! People sign up in good faith. Shame on you.
