also - the issue w/ old email arriving is most likely due to the message ID's of your old email changing - and therefore BIS seeing them as new and sending them to your handheld - this is a Yahoo! issue
I actually think it is a combination of Yahoo! and BIS/RIM problems which makes it even harder to debug, especially for the recipient at the end of the e-mail delivery chain: Me!
One strange thing I noticed is that if I mark an email as spam in Yahoo! Mail, and then mark it back as not spam it gets pushed to my BB after about 15 minutes. I did this with the 4 emails I didn't get last night, and got them all on my BB. It's also weird that most of the problems happens at night. During the day everything seems to work smoothly, but come 8 PM (Central US time) things go wrong again.
As long as I am not loosing mail all together I can (sorta) live with it. It's annoying though and I hope things go back to stable soon.
