OK, I try without any custom header (this email). I removed all my_hdr
fields to try. Note that this email is sent from another computer than
the previous one (dev-libs/libgcrypt-1.7.3, mail-client/mutt-1.5.24-r2,
app-crypt/gnupg-2.1.14-r1).
Before sending this email, I have checked by sending one to myself: the
sig appears to be GOOD.
