but this uses gnus-no-server, which obviously starts Gnus.  Is there a
more efficient way to accomplish sending mails outside of Gnus, such that
a) a copy of the message is sent to myself¹, or b) a Gcc header is used,
causing the message to be stored in gnus-message-archive-group?

Thanks in advance for any suggestions,

Sebastian

¹ Using e.g. Bcc, being careful to add my address if such a header already
exists with some entries, or the header is added with my address in it.
