I did as directed. I moved all the Zimbra lib entries to be read first in ld.so.conf and ran /sbin/ldconfig. Web mail still works, Thunderbird was denied, but the errors about the wrong libs vanished.
I connected to the host with netcat
Code:
robertl@pele:~$ nc domain-name.com 25
220 blueline.domain-name.com ESMTP Postfix
helo blueline
250 blueline.domain-name.com
starttls
220 Ready to start TLS
With some more reading about postfix I will take nc testing further and see if I can't get you some more info. I think it's using the correct libs now. I am still seeing the auth logging but the libsasl errors are no longer showing.
Thoughts?
Thank you,
Bob
