Hu I've a strange problem with my #postfix #smtpd (I presume?) . Trying to send a mail trough it with #thunderbird , it fails with the error:
> Peer’s Certificate issuer is not recognized.
my cert is issued by Let's Encrypt and is not expired.
In postfix's logs I get this:
> smtpd[552582]: SSL_accept error from unknown[176.x.x.x]: -1
> smtpd[552582]: warning: TLS library problem: error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca:../ssl/record/rec_layer_s3.c:1571:SSL
I completely forgot to post about the OpenSMTPD 7.6 release! I'm so late that we also did 7.6.0p1 in the meantime, but that's only because I forgot a few files in the tarball
