It has come to our knowledge that Yahoo!/AOL has now imposed new limits on how many emails can be collected per folder when collecting via the IMAP protocol. The limit is 10,000 emails per folder.

If you use a search query or try to collect all the emails from an account, you will only be provided 10,000 emails per folder.

We are currently looking into what can be done in Aid4Mail to work around these limits.
