[HacktionLab] hotmail bouncing mail

[Marcus Valentine]

Since last Saturday, hotmail have taken to bouncing mail addressed to
them originating from my server.

There's nothing that jumps put at from their help page at

https://mail.live.com/mail/troubleshooting.aspx#errors.

Have anyone come across this sort of thing before? Any suggestions?

Marcus
