I've just configured my postfix 2.6.6-6 mailserver to use a relayhost with tls, and I'm seeing warnings when I send mail. Here's an example:
May 18 19:41:21 lion postfix/smtp[3625]: certificate verification failed for mailout.example.com[x.x.x.x]:587: untrusted issuer /C=US/O=Equifax/OU=Equifax Secure Certificate Authority It appears the correct solution is to specify smtp_tls_CAfile in main.cf. That's easy enough to do, but I'm not sure which file to use. This is a CentOS 6.6 system. If I do a locate on .crt, here's what I get: /etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt /etc/pki/ca-trust/source/ca-bundle.legacy.crt /etc/pki/tls/certs/ca-bundle.crt /etc/pki/tls/certs/ca-bundle.trust.crt /usr/share/pki/ca-trust-legacy/ca-bundle.legacy.default.crt /usr/share/pki/ca-trust-legacy/ca-bundle.legacy.disable.crt /usr/share/pki/ca-trust-source/ca-bundle.neutral-trust.crt /usr/share/pki/ca-trust-source/ca-bundle.trust.crt So many to choose from! Which should I use? thanks, galen -- Galen Seitz [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
