mail passowords not accepted
I did an update to OS 10.11.6 and found after restart I couldn't access four of my email accounts - had to put passwords in. I know I am using the correct passwords, but they are rejected as not verifiable. Between this and all the verification codes it makes me never want to to a software update again.
Please help! I need to be able to access my mail. Thanks you.
iMac, OS X El Capitan (10.11.6)
