DESCRIPTION

Net::IMP::Filter is a class which can be used for simple filters (e.g. data in, data out) using Net::IMP analyzers, thus hiding the complexity but also useful features of the Net::IMP interface for simple use cases. To create such a filter subclass from Net::IMP::Filter and implement any of the following methods (which by default do nothing)

out($self,$dir,$data)

this gets called for output of data

deny($self,$msg,$dir)

this gets called on IMP_DENY

log($self,$level,$msg,$dir,$offset,$len)

this gets called on IMP_LOG

acctfld($self,$key,$value)

this gets called on IMP_ACCTFIELD
