GrayWall
Graywall is a program that adds a graylist (or greylist) feature to the Mercury/32 SMTP server. It uses the Mercury/32 API facility that has been introduced in version 4.51. You must have at least this version of Mercury/32 to run Graywall!
Information about graylisting in general can be found at: http://en.wikipedia.org/wiki/Greylist. We recommend that you read this first.
The basic features of Graywall are as follows:
- It accepts some incoming SMTP sessions and rejects others according to certain conditions.
- Authorized connections, or connections from specified IP addresses, are not affected by Graywall.
- Graywall is compatible with the sending of SMTP mail by server farms.
- Graywall is compatible with the “reverse delivery test” used by some systems as an anti-spam test (for example, Sourceforge.net).
- Servers which successfully pass mail through are whitelisted by Graywall for the specific mail domain, and subsequent messages are not delayed by Graywall.
- Support for whilelisting of incompatible servers by external file. See: http://www.greylisting.org/whitelisting.shtml
