I have install the 3.1.1 zimbra but I didn't find what's new in the admin console
than how to setting the spamassassin
I find some configuration in the /opt/zimbra/conf/spamassassin/*.cf
I modify the 60_whitelist.cf and 60_whitelist_subject.cf add a mail server like this:
def_whitelist_from_rcvd billing@networksolutions.com networksolutions.com
def_whitelist_from_rcvd outbound-response@networksolutions.com networksolutions.com
def_whitelist_from_rcvd hostmaster@internic.net internic.net
def_whitelist_from_rcvd support@register.com register.com
def_whitelist_from_rcvd *@*.xxx.net xxx.com
I sent a mail from xxx.com to my zimbra server it display in the junk
the /opt/zimbra/dspam/var/dspam/system.log write like this:
1148448686 W root <root@mail.sina.net> 4473efae9241804284693 sdlkf 0.014507 zimbra Auto-Whitelisted <200605240531.k4O5VPoE000922@mail.sina.net>
