Hi Guys,
I thought I add my few pence here too 🙂
I've been using Postbox when I realised that Mail isn't a go anymore with Gmail, as I'm using Gmail Business Apps with my domains pointing to their servers for email and Postbox works fine.
I've also just started using Airmail - wanted to see whether it will work and it see to work ok, however - problem with both of the applications is that they don't fully support MS Exchange - and I have one for work, which causes a problem for me. Airmail has Exchange option, but it doesn't seem to work with our setup.
While Mail was supporting both until the release of Maverick - I now have to check my Exchange mail via browser and have Gmail syncronised with third party mail app. Not great at all Apple, but aren't we all used to it now?
I seriously start thinking about switching to some Linux flavour if the problems with Apple will continue.
