=head1 NAME

Email::Folder::IMAP - Email::Folder Access to IMAP Folders

=head1 SYNOPSIS

  use Email::Folder;
  use Email::FolderType::Net;
  
  my $folder = Email::Folder->new('imap://example.com'); # read INBOX
  
  print $_->header('Subject') for $folder->messages;

=head1 DESCRIPTION

This software adds IMAP functionality to L<Email::Folder|Email::Folder>.
Its interface is identical to the other
L<Email::Folder::Reader|Email::Folder::Reader> subclasses.

=head2 Parameters

C<username> and C<password> parameters may be sent to C<new()>. If
used, they override any user info passed in the connection URI.

=head2 Folder Specification

Folders are specified using a simplified form of the IMAP URL Scheme
detailed in RFC 2192. Not all of that specification applies. Here
are a few examples.

Selecting the INBOX.

  imap://foo.com

Selecting the INBOX using URI based authentication. Remember that the
C<username> and C<password> parameters passed to C<new()> will override
anything set in the URI.

  imap://user:pass@foo.com

Selecting the p5p list.

  imap://foo.com/perl/perl5-porters
