This part, at least, I can explain: mutt (and mail) knows nothing about
the aliases in /etc/aliases. It only knows its own aliases (defined in
.muttrc).
Any mail sent to an address without a hostname is for the local system
by default, so mail to just "root" gets @localhost appended.
The aliases in /etc/aliases are handled by the MTA (postfix, in your
case), so it attempts to deliver the mail to root@localhost, but checks
its own list of aliases and sees that mail for root@localhost should be
delivered to to@recipient.domain and forwards it there. It doesn't
touch the To: header in the process, because, if it did, then you
wouldn't have any way of knowing what address your mail was sent to,
only where it was finally delivered to after all forwarding, etc.
If you want the address in the To: header to match the final delivery
address, you'll need to create a mutt alias for "root" which maps to
that address, either manually or (as already suggested) with a script
that translates aliases from /etc/aliases to .muttrc.

I know and ... honestly: I posted here in the hope that someone could
suggest an alternative way to send notifications from BackupPC,
because
I went insane trying to send attachments with sendamil provided by
Postfix ...

Thank you so much for your answer!
