=====Configure:=====
Once you do this a new menu item will be visable in the Server-Manager on the left hand side, called '''E-mail WBL'''. Traffic is scanned and may be blocked due to the various screening methods enabled. Clicking on this will present you with 3 buttons.
You may use this panel to define e-mail white/black lists and RBLs.
RBL's List is used to adjust DNSBL and RHSBL.
'''[RBLs List]'''
Black lists are used for rejecting e-mail traffic.
Black lists are used for rejecting e-mail traffic.
'''[REJECT]'''
'''[Black List]'''
White lists are used for accepting e-mail traffic.
White lists are used for accepting e-mail traffic.
'''[ACCEPT]'''
'''[White List]'''
If you press the Black List button you will see the following window.
[[File:email-Reject.jpg]]

If you press the Accept button you will see the following window.
If you press the White List button you will see the following window.
[[File:Email-accept.jpg]]
[[File:Email-accept.jpg|842px]]

And finally If you press the SAVE button this will apply any of the changes you made, wait for confirmation message.
===Usage Examples===
===Usage Examples===
Black Lists: REJECT
====Black Lists: REJECT====
=====Plugin: Helo=====
White Lists: ACCEPT
Format:
some.host.domain
Add domains, hostnames, or perl regexp patterns to the <badhelo> config file; one per line.
{{Note box|You cannot block HELO IP addresses with this plugin. It is not designed to do that. Please look at other methods such as direct IP blocking via the firewall, or contribs like Fail2ban, GeoIP, xt_tables}}
https://github.com/smtpd/qpsmtpd/blob/master/plugins/helo
Matches in the <badhelo> config file, including yahoo.com and aol.com, which neither the real Yahoo or the real AOL use, but which spammers use a lot.
Like qmail with the qregex patch, the <badhelo> file can also contain perl regular expressions. In addition to normal regexp processing, a pattern can start with a ! character, and get a negated (!~) match.
=====Plugin: Badmailfrom=====
Format:
@host or user@host
This plugin also supports regular expression matches. This allows special patterns to be denied (e.g. FQDN-VERP, percent hack, bangs, double ats).
Patterns are stored in the format pattern'''(\s+)'''response, where pattern is a Perl pattern expression. Don't forget to anchor the pattern (front ^ and back $) if you want to restrict it from matching anywhere in the string.
