It looks like your ISP is on Microsoft's blocklist. You should check with
them. See below, your message is bouncing to all silklist addresses within
the Microsoft universe:
550 5.7.1 Unfortunately, messages from [50.23.85.242] weren't sent.
Please contact your Internet service provider since part of their network
is on our block list (AS3140). You can also refer your provider to

Looks like the IP block of lists.hserus.net is on Microsoft's blocklist.
Not Tomasz's.
