Mail::ListDetector::Detector::Onelist is a ONElist message detector.
An implementation of a mailing list detector, for ONElist mailing lists. ONElist was eaten by eGroups which became Yahoo! Groups so this detector is really only useful for historical mail.
Inherited from Mail::ListDetector::Detector::Base.
Accepts a Mail::Internet object and returns either a Mail::ListDetector::List object if it is a post to a ONElist mailing list, or undef.
