Email Whitelist-Blacklist Control
Maintainer
Originally developed by Darrell May.
Version
Description
This contrib provides a server-manager panel to designate user defined email whitelists and blacklists.
An email whitelist is a list of hosts, domains, or email addresses which will be accepted by SME Server regardless of possible spam content or origin. Administrators should use caution when using whitelists as email coming from whitelisted addresses will bypass many of the mechanisms that SME provides for identifying unsafe email messages.
An email blacklist is a list of hosts, domains, or email addresses that will be blocked all of the time.
Installation
Install of the lastest Email Whitelist-Blacklist package is from the smecontribs repo:
1. Install package:

You may use this panel to define e-mail white/black lists and RBLs.

Usage Examples
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.
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
