SYNOPSIS

See SYNOPSIS in Mail::Message::Head

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...
