It would be very fine, which can enable you and other Priority mail! And left the banner can close shut for privacy and broader e-mail have list! And can also turn the Recycle Bin automatically, as soon as I add mails to trash, that e-mails in the Recycle Bin automatically deleted when I close my Yahoo mail! I have not always to trash, need to remove even permanently! It only costs additional time and waste! I hope you can solve these four things as all providers to have too? And also sign instead of e-mail address, you can log in with registered mobile number? Would be very nice must enter each time with your email address! I hope you can solve even in that field over there ...
