@section Why is the mailing list munging my address?
This is due to subscribers that use a mail service with a DMARC reject policy
which adds difficulties to mailing list operators.
The mailing list must re-write (munge) the @emph{From:} header for such users;
otherwise their mail service will reject and bounce the message resulting in
automatic unsubscribing from the mailing list.
When sending a message these users will see @emph{via <mailing list name>}
added to their name and the @emph{From:} address munged to the address of
the particular mailing list.
If you want to avoid this then please use a different mail service.
