Thunderbird - Sent messages marked unread in gmail


New Email

I am using Thunderbird 7.0.1 on Mac OS X 10.7.2.

When I send a message using Thunderbird, for a Google Apps/GMail account, the email shows up on my Android phone as UNREAD.

Any ideas how to mark it as read when sending?

It confuses the conversation list and I think there is a NEW message from someone when it's just me.

Thank you!
