I moved from Microsoft's feature-rich Entourage mail recently to bring my email into the house of Apple to get more Apple mobile stuff like iPhone --- and synchronise it all.
But since coming to Mail I have read so much that says Apple Mail is so rudimentary, and has so many problems including this and many others. And they reach back into Snow Leopard.
Apple Mail is such a poor relative of all the other Apple products it seems like it is in anohter time zone.
I hope Apple realise that some people (or increasing numbers maybe) will migrate to Apple Mail just to pick up synchroniicity off iCloud, for their laptop and iPhone. so they can service their email on the move away from the desk.
Also I hope they realise that a significant part of their market is serious professional people who rely on Apple Mail as infrastructure which is as important a electricity, gas, and the water. We can't live out here without email any more. Why migrate to a flaky neglected utility?
How can Apple let these problems lie for year after year and just concentrate on flogging music and video to kids(and, well, me occasionally).
In the next year I will have to decide whether remaining loyal to Apple (since 1988) is the way to keep going, or to buy the Google Android product, go Gmail and use their cloud co-ordination.
Goodbye iPhone hello Samsung.
