[White List] 

Format:
 some.host.domain

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.

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.

 ===Usage Examples===
-Black Lists: REJECT
+====Black Lists: REJECT====
+=====Plugin: Helo=====
+ 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}}

-The '''qpsmtpd badhelo''' is effective in examining the SMTP HELO string and then block mail based on this string.  Entries follow the following format.
- something.a.somehost.com
-To find the proper string to enter on the qpsmtp badhelo line. 1. Open an offending email. 2. Open the header of the email. 3. Look for a line that says,
-(HELO something.a.somehost.com)
-Partial strings will not work, E.G. in the previous example somehost.com will not work. It must be the complete HELO string.
-{{Note box|Using qpsmtpd badhelo will stop all mail at a domain that uses that specific HELO string. It's not looking at a specific email. This strategy isn't always effective as spammers generally change this field to stop this kind of detection. Also companies have several SMTP gateways so you may see mail from mail1.domain.com and mail2.domain.com . You will then need to add both of these. The advantage  however is if you do want to stop all mail from one source, it can be effective. }} Alternatively you may use the ip address. Again look in the header for the Helo line. It may look something like this,
-Received: from smtprelay0207.c.somehost.com (HELO smtprelay.c.somehost.com) '''(123.111.123.321''')
-Now simply add the IP address you found in the HELO line.
-.111.123.321
