I would love to hear what people use.
Apples own mail client, how does that one work with multiple gmail accounts and also with contacts. I have no interest in merging all my gmail contacts with my phone book, will mail then be able to autocomplete addresses? And can I search through all my google emails without downloading all my emails?
I've been using Postbox for severals months now and am very happy with it. I got tired of some IMAP issues with Apple Mail and really love a lot of the filtering options in Postbox. I think the search capabilities are far superior too.
