I don't know what else to do to fix this. My phone keeps crashing cause the mail app keeps downloading mails. I heard there was an option for POP mail that allowed mail for "x" number of days. I can't find this option now.. and someone suggested that IMAP mail would allow mail for a certain number of days. Basically how do I switch mail to IMAP and would it solve the issue of my mail app constantly downloading 150+ emails ??
