Email not getting delivered

[George Wright]

Hi,

I have a Kolab 3 setup, and I noticed I was supposed to receive an email
(from Steam Support at Valve, if that's relevant) but it never got
delivered to my mailbox.

Delving into the logs shows nothing out of the ordinary:

mail.log:Mar  4 18:41:53 mail postfix/qmgr[3077]: 0730910E054:

Any ideas?
