version 3.005: Fri 3 May 09:41:53 CEST 2019
Fixes:
- wrong place to set default message type.
- transporter should differentiate between pop3 and pop3s in url().
Improvements:
- cleanup ::POP3 coding style.
Maintain a folder which has its messages stored on a remote server. The
communication between the client application and the server is implemented using
the POP3 protocol. This class uses Mail::Transport::POP3 to hide the transport
of information, and focusses solely on the correct handling of messages within a
POP3 folder.
