MacBook pro suddenlink email issues after yosemite install.

Question

After installing yosemite on my 15" MacBook Pro I have had issues with my suddenlink email account. I went through all the settings yesterday with a sudden link representative and did find a port was wrong and corrected that on my outgoing server. However I never could update my password successfully using Preferences, Account, Password. It would let me save it, but would not actually change it, as confirmed by the connection doctor. So reading some other threads here I went to my provider and changed my password there, to make sure everything was correct. I updated the passwords on my iPhone and iPad, and both accounts are working correctly (they always have been working properly). I deleted the sudden link account from my MacBook, and reinstalled it with the correct new password, it was working fine all day yesterday and then this morning when I got back on my MacBook, I have the triangle exclamation point symbol next the sudden link account again. Tried re-entering the password via preferences tab and no luck, verified with connection doctor that I couldn't connect, it gave me the same error,  verify password and username is correct. I deleted and re-installed with correct password, and it works again. Any suggestions as to why this is happening?
