When I send a mass mail I don't receive the mail from my forum. (the order users do)

I thought it might be a permissions problem or something so I've investigate some of my own.
This is the thing that I have found.

I have Jabber disabled, but for some reason when I look in my profile via the ACP to my Board Preferences I saw that the notification style was set to BOTH. (I can't check Jabber because it's disabled).
I have set the notification then to E-mail and then I receive mass e-mails from my board.

So it seems that the board is not sending out emails when the notification style is set to Both.
Another thing is, that I have disabled Jabber, so it even might not be possible to check both, because it's not active!

Best regards,
