I don't use the laptop regularly for mail but I did update its inbox
today just to check out what it does now.
gpg2.1.7 with enigmail 1.9a1 of 30 Nov 2015 verifies all your emails of
2015 as 'good signature'. However, when I look to see more details, the
verification behind the enigmail 'Details' button quotes key ID
0x547B7194 which is the RSA 2048 public key identity.
But when I look into the enigmail log, there I see that signatures were
made by both EDDSA subkey 0x1712BC461AF778E4 and RSA subkey
Getting back to the desktop --
On my desktop with 2.0.22 with enigmail 1.9a1 of 8 Oct 2015, enigmail
provides differing info depending on whether you're inline or pgp/mime.
The latter gives the more alarming info behind enigmail's Details button
"Untrusted bad signature ...."
But again, enigmail's logfile shows both subkeys were used. Enigmail
doesn't use the available info which is there in the logfile wrt the RSA
key ...(I quote from the logfile)...

Never mind the trust issue. The logfile does show "good signature".
