In Mail under Account Preferences my incoming mail server is grayed out and I can receive mail.
I haven't been able to receive mail this morning but can send it. I checked under 'Preferences' 'Accounts' and the Incoming Mail Server is grayed out. I can't make any changes to that. Is this a problem on my computer or is it with the server?
iMac, OS X Yosemite (10.10.5)
