I set up my Verizon.net email account and it all goes thru. I can send emails but none of messages load and I can't receive any. Talked to Verizon on the phone they couldn't figure it out. They told me to try k9 mail. I tried it and it worked for a day and then stopped. I deleted it and got it again and same thing. One day and done. Would like to use the stock app. Any help?
