4.1.4 Pragma greylist

 
#pragma greylist type

This pragma selects the greylisting implementation to use. Allowed values for type are:

traditional
gray

Use the traditional greylisting implementation. This is the default.

con-tassios
ct

Use Con Tassios greylisting implementation.

See greylisting types, for a detailed description of available greylisting implementations.

Notice, that this pragma can be used only once. Second use of this pragma constitutes an error, because you cannot use both greylisting implementations in the same program.
