No, your filter file isn't affected by being a trusted user.
Users listed in the trusted_user setting are allowed to override Exim's idea
of who the original sender of a message is. So in this case, we want
fetchmail to be able to specify the sender of the message to whatever value
it derivce from the POP3 server. If the user is not trusted, then submitting
a message using this form will set the sender to the username '@' the
qualify_domain setting.

-oem is just specifying how to report submissions errors back to the caller
(i.e. by returning a non-zero exit code).

The "received protocol" is an attribute of each message in Exim's queue. If
you wubmit a message to Exim via the command-line interface, then by deafult
the received protocol is "local". But trusted users can override this too
using -oMr. So in this case, I override the received protocol to
"fetchmail", which shows up the Recevied: headers, and also means that I
scan the messages with SpamAssassin (which I don';t do for messages received
using "local").

fetchmail replaces %F and %T with its ideas of the message envelope sender
and recipients, respectively.
