My question is _only_ about SMIME. GPG proper and GPG signatures work
fine for me. I see that your message was SMIME signed so I assume SMIME
does work for you.
Do you have a ~/.gnupg/gpgsm.conf file? Can you share it?
For GPG, if a key is not present in the local system it is automatically
fetched from a keyserver; that keyserver is specified in
~/.gnupg/gpg.conf . Is there a similar mechanism for gpgsm? If yes,
what keyserver is commonly used?
Also, when I verify a GPG signature, they key fingerprint is included in
the output that neomutt displays, and from the fingerprint I can derive
the key ID. This way, when there is a problem with the signature, I can
try to download the key (with gpg --recv-keys) to narrow the problem
But this doesn't seem to be true for SMIME. The output includes some
long hex string but there is no apparent relation between that hex and
the key ID, as it is displayed by gpgsm --list-keys. I see this
because _your_ signature now does verify correctly so I know the key
with your address in my keyring is the one you used to sign your message.
Thanks for your explanations. You see, I have only ever used GPG, and I
have no idea about SMIME.
