====Black Lists: REJECT====
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.
123.111.123.321
Badmailfrom
@host or user@host
====White Lists: ACCEPT====
