Just a correction to my previous statement:

I did start seeing some TLS handshake failures with the Debian/Ubuntu
certificate bundle and "tls_try_verify_hosts = *". So it looks like
there are few mail senders who use some of the broken GnuTLS versions.

Thus it is not a good idea to run such a setup in a production
environment. Reducing the amount of CA's or disabling
"tls_try_verify_hosts" solves the problem until we get the "don't
advertise CAs" knob in the next release :).
