Hello,

I'm trying to use an smtp_tls_policy_maps with a tafile (2.11.0 on Ubuntu 14.04.2 LTS) but I receive the error in the subject.

        smtp_tls_policy_maps=texthash:/etc/postfix/mymap

        mymap:
subdomain.mydomain.com verify tafile=/var/lib/postfix/my_intermediate

The my_intermediate file contains a valid intermediate CA certificate in PEM format and it is readable by postfix user:

# openssl x509 -in /var/lib/postfix/my_intermediate -inform pem -noout -fingerprint SHA1 Fingerprint=CB:1A:60:EB:50:B2:51:D5:4E:05:01:D0:FD:E2:A0:6D:BF:4F:5B:FC

This is the log:

Can someone help me troubleshooting this issue?

Many thanks.
