Hello,
I've noticed not all of my mail from certain recipients not always being delivered. When looking in the tracking logs I notice the following error when I search for the sender mail adress:
No suitable shadow servers,,SMTP,HAREDIRECTFAIL
Googling this does not come up with much, does anyone have a clue what this could mean?
