Airmail in beta

Works great I use it as my main mail client, loads of updated often. I sent a bug report and the issue was fixed the same day.

It's free the now, but if I recall they will charge when it's fully released.

I like it.

Just discovered the app on one of my rare checks of the Mac App Store. Impressed its currently #1 Top Paid in the German app store, ahead of Mountain Lion.

So I was googling for more info about the app and found this thread.

4 emails in trash won't delete

I've got 4 deleted emails in the trash that I am unable to delete. The 4 that are in the trash are greyed out and have a gold colored triangle and gold text next to it that says: "Performing sync." I can't empty just those 4. All the rest of the emails in the trash will delete though. I am new to this Airmail app. How can I get rid of those 4 deleted emails that remain in the trash. Anyone else see that?
thanks for a reply....
