Windows 7. When trying to "Get from ALL current accounts" nothing happens. I have a few IMAP accounts configured and "Get from current account" works fine. As checking for messages on all accounts doesn't work "check for new mail every" and "check for new mail on start-up" doesn't work either.
I'm sorry. I'm new to Claws Mail and obviously missed that you have to check accounts from which "get mail" should receive messages. the word "all" is very misleading.
