In the past two months I’ve been getting this message quite frequently when using Apple Mail with Gmail. “The server returned the error: Account exceeded bandwidth limits. (Failure)”.

Having googled online I’ve found quite a few occurrences of this error out in the wild. Some say that this may be triggered by sending an extra large file as an attachment. Now I have not done that recently so it can’t be it.
My guess that this has something to do with Apple Mail and the way it communicates to Gmail. There must be some sort of an overhead that causes this “bandwidth exceeded” message. The forums indicate that this problem presents itself mostly on Snow Leopard OS X.
Usually this problem goes away in 24 hours. Unlocking your Google account from did not seem to do the trick.
There is an ongoing discussion of this issue at Google.
I’m yet to find an explanation for the absence of a proper To Do functionality on an Apple platform.
Whatever is available out there seems more like an after-thought.
We have a To Do functionality built within the iCal app, it works great, syncs between multiple computers via Mobile Me, but there’s no iPhone app front end of any kind. Third party applications are also restricted from accessing it without installing any plugins.
Ability to create a task within Mail app is great, but the To Dos now are stored within Mail in a Note form. That is somewhat akin to having a separate RSS aggregator in Mail instead of Safari. The rationale for it is somewhat not clear.
Finally there are third-party apps, some of them quite great. But you are either limited to using your iPhone as the only mean of entering information, or you have to visit a website or install a plugin.
With a release of an iPad and its gorgeous Calendar application, an absence of a To Do functionality streamlined across the full platform seems awkward at best.
