Question for any others out there using OS X (if it matters, V. 10.9.1) - So, the mail application in OS X is a POS but I felt like it had been getting better in terms of actually delivering mail on a semi-reliable basis over the past few weeks. However, the past couple of days it's been back to it's super-laggy self (really, you're not going to deliver mail during a whole 8.5 hour span?). Is anyone else experiencing this or is it just me?
