This is what the "Show" link next to the "Outgoing email recorded"
button is for.

All ->Set... methods return a tuple of ($success, $msg).  You'll find
that $success is false, and $msg is telling you that the field is
read-only.

RT views attachments as effectively immutable.  Changing this invariant
is complex, and not generally recommended.
