Don't always assume this is the case. I work in the industry of email
discussion list software and I've seen too many instances where 'silent
filtering' was taking place somewhere upstream, even though the user
swore up & down that they didn't do any filtering themselves. ISPs,
corporate gateways, etc, are all spots where it can take place well out
of your control (or knowledge).
More and more organisations are enabling filters and the message
doesn't always get out to the users. If you ever have email go
missing, start asking questions. You may be very surprised at the
