NAME

Mail::Box::MH::Labels - maintain MH message related labels

INHERITANCE

 Mail::Box::MH::Labels
   is a Mail::Reporter

SYNOPSIS

 my $labels = Mail::Box::MH::Labels->new;
 $labels->read(...)
 $labels->write(...)

DESCRIPTION

MH type message folders use one dedicated file per folder-directory to list special tags to messages in that folder. By doing this, mail agents may avoid parsing all the messages, which is very resource consuming.

Labels can be used to group messages, for instance to reflect which messages have been read or which look like spam. Some labels are predefined, but more can be added without limitation.

Extends ``DESCRIPTION'' in Mail::Reporter.

METHODS

DIAGNOSTICS

Error: Package $package does not implement $method.: Fatal error: the specific package (or one of its superclasses) does not implement this method where it should. This message means that some other related classes do implement this method however the class at hand does not. Probably you should investigate this and probably inform the author of the package.
