alfred.gayleard.eu does exist. It is the name of my server.
/etc/postfix/main.cf asks you for your host name and your domain name.
It does not ask you for your mx record.
If as you imply it actually wants my mx record,
would it not be simpler to ask for that?

Incidentally, that was not the cause of the problem,
as I tried with several entries to myhostname, including gayleard.eu,
and the From address was set to localhost.localdomain in all cases.
