Securing Zimbra MTA

[tron]

How do I tell which one is my default domain? Does smtp auth only work with default domain?

are the accounts with external auth not in default domain?

SMTP SASL authentication failure

That is what I was referring to.

I have made the changes so saslauthd is starting with -r, see below. But I am still having problem logging with with users from domains other than the default domain.

ps auwx | grep saslauthd

It is working now. It turned out to be a mistake on my part. I was not encoding the AUTH LOGIN correctly for my test.
