User whitelist/blacklist format
What are the different formats that can be used in the user whitelist/blacklist entries in the Zimbra 6 mail preferences? I believe that an exact match can occur by just specifying an email address:
and I think you can have an entry applicable to everybody at a domain:
But, what if you want to match everybody at any subdomain of example.com? @*.example.com doesn't seem to work. Or, what about matching a sender name, regardless of the domain (e.g., special-offers@*)?
Is there a complete list of the different formats available?
