NAME

Mail::Box::IMAP4::Head - header fields related IMAP interface

INHERITANCE

Mail::Box::IMAP4::Head
  is a Mail::Message::Head
  is a Mail::Reporter

SYNOPSIS

DESCRIPTION

This class implements a pure IMAP4 protocol interface, where as little data is retrieved from the header as possible. This may look nice to you, but is not sufficient for many tasks. For instance, you cannot removed or modify fields this way.

Change Mail::Box::IMAP4::new(cache_head) to YES or DELAY, to get a message header which is capable of performing all possible games with headers. On the other hand: the other settings are not 100% safe...

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. Cast by notImplemented()
