Hello Pierre,
thanks to your recent commit (852ae64e11 gnu: Remove emacs-seq package.)
I was able to upgrade to emacs 27.1: kudos \O/ !
I'm using notmuch as MUA and experienced this signing problem too:
--8<---------------cut here---------------start------------->8---
mml-secure-epg-sign: Couldn’t find any signer names; try setting `mml-secure-smime-sign-with-sender'.
--8<---------------cut here---------------end--------------->8---
when trying to sign **with openpgp**, non with S/MIME (aka I use the #secure
method=pgpmime mode=sign" tag)

No need to explicitly set this if:

^ s/gpg/pgp
I set (setq mml-secure-openpgp-sign-with-sender t)

This used to just work by default for me too, probably it's due a change
in default behaviour of message mode [1]:
--8<---------------cut here---------------start------------->8---
*** 'mml-secure-openpgp-sign-with-sender' sets also "gpg --sender".
When 'mml-secure-openpgp-sign-with-sender' is non-nil, message sender's
email address (in addition to its old behavior) will also be used to
set gpg's "--sender email@domain" option.
The option is useful for two reasons when verifying the signature:
1. GnuPG's TOFU statistics are updated for the specific user id
(email) only. See gpg(1) man page about "--sender".
2. GnuPG's "--auto-key-retrieve" functionality can use WKD (web key
directory) method for finding the signer's key. You need GnuPG
2.2.17 to fully benefit from this feature. See gpg(1) man page for
"--auto-key-retrieve".
--8<---------------cut here---------------end--------------->8---
I still do not understand why the "old behaviour" doesn't work with 27.1
(with 26.3 worked) but you have found the solution :-)
Thanks! Gio'
