I downloaded the "latest" version and love it. But I do have some problems.

1). Sent mail is not being copied to the sent folder. I have set the preference to save a copy of all emails in SENT but it doesn't work. I tried experimenting with the flag but nothing seemed to work.

2). Some emails I send to receipients are not being received by them. If I respond to a calendar request (accept for example), they get the response. But if I send them a regular email they don't get it.

I'm receiving email fine though.
