cannot send email on iMac. how do you delete an account from Connection doctor
I cannort send email from my yahoo and comcast accounts on iMac. I have noticed that when I go to Connection Doctor and additional account which cannot connect is listed. I have two yahoo accounts and two comcast accounts but an additional yahoo account listed as smtp.yahoo.com appears and cannot connect. I believe this is causing my email problems
iMac, OS X Yosemite (10.10.5)
