In YAMN, the option called "Only check when..." is somewhat misleading.
The sentence indicate that you can add exceptions as to when YAMN should NOT check for new mails, when in fact, it's the other way around.
To make things worse, all checkboxes are unchecked by default, so YAMN will never check for mails unless you open this submenu and configure it to your liking.
Either all the checkboxes should be checked by default, or the button for this submenu should be renamed to "Check when...".
