Comment 1 for bug 1495904

Some more tests (sorry for my bad english):

if in the received mail page there is a couple of mail (~50 in my case, some read and others no), account-polld reports only the last mail which sender don't already exists in the list (so only the first time the sender sends a mail, after this it's address is already in the page and new messages from him are ignored)
I receive periodic mails from my home automation system and them are never notified, the same for mails from google or launchpad. only new senders, only once.

I expect somehing like account-polld caches the timestamp (or something like) of the last mail notified and then periodically check only for more recent matches, if the match is true, then notifies the mail and caches the new timestamp. And so on. This regardless of the sender.

Although i admit that my test results are in contrast with the case when the account is deleted and then recreated in the phone. In that case, only the oldest unread mail is notified.
