I've set my academic webmail client to forward "all" messages to my Gmail and it has been doing it very well for around 2 years!.
Today by chance I checked my academic web client and found an email message which surprisingly was not forwarded to my Gmail address.
This really concerns me as from today I'm not quite sure that I'm receiving every messages sent to my academic mailbox.
What can be the possible reason? What could happen to that single message?
