e-mails constantly reloading
Os X el Capitan, version 10.11.6
Mail version 9.3.
My mails are constantly reloading, even though they were downloaded already. constantly about 15'000 emails downloading. Any suggestions how to resolve this problem? Delete and re-installation of the account didn't work.
