Comment 1 for bug 1595325

Mail can be very busy, e.g. after creating a new account and opening the inbox it reads all the emails that are listed in the conversation view on the left.

You can see what Mail is doing when you start the app from the commandline with the "-d" parameter added. Mail then prints out what it is doing.

So, when it takes some time until any messages are displayed, Mail should be busy doing something else then.

Could you please verify this?
