I have installed 4.5.6, 4.5.7 and 4.5.9 and out-of-the-box (ie, using the certs that are generated during installation), none work with SMTP Auth over TLS on my Ubuntu 6.06 server. I've checked the AuthURL and other settings per
this article and everything is in order.
In answer to some earlier questions:
- Yes, I am a network edition customer, but this is an open-source installation we use as part of our evaluation process in previewing and testing new releases. So support may not be available through the usual channels.
- I need to regenerate the certificates to add some aliases that this server can be contacted on (two different host names on two different domains).
I would really like to increase the verbosity in the postfix logs but I'm a little unsure of the best way to go about this in a persistent manner; any changes I've made get hosed when I restart zimbra or do "postfix reload".
More info would certainly help shed some light on where the problem is.
