OSX 10.9.4 Mavericks broke email

I upgraded to OSX 10.9.4 Mavericks and boom my POP email account stopped working, it says I have an incorrect password when I know my password is right, I have my ISPs settings right and I can connect via webmail just fine, and I can connect and send iCloud email, so the problem is with OSX - Apple please fix your email!

And Apple, please fix iTunes, for some strange reason, iTunes no longer lets me delete podcasts, after I listen to a podcast, I want to delete it, Apple has decided not to let me delete podcasts. Apple please fix this.
