Lately @mozilla @thunderbird has been a bit ass. It lets spam through to the desktop and mobile client, where other email clients (notably Evolution on Linux) don't. Even though I clearly mark something as spam, I still see it.
And this is even though Gmail itself blocks it and sends it to the spam folder.
I prefer the desktop version for email. But seeing spam just sucks.
