-The fetchmail code was developed under Linux, but has also been
-extensively tested under 4.4BSD, Solaris and NEXTSTEP. It should be
-readily portable to other Unix variants (it uses GNU autoconf). It
-has also been ported to QNX; to build under QNX, see the header
-comments in the Makefile.
-
-For those of you already familiar with previous versions, here are the
-major new features since 3.0:
-
- ** Support for ESMTP 8BITMIME and SIZE options
-
-There have also been numerous improvements in multidrop mailbox handling.
-Under many circumstances fetchmail can now determine a mail message's
-envelope address from its headers, making multidrop forwarding more reliable.
-
-Here are fetchmail's main features. Those unique to fetchmail
-(relative to fetchpop1.9, PopTart-0.9.3, get-mail, gwpop, pimp-1.0,
-pop-perl5-1.2, popc, popmail-1.6 and upop) are marked with **.
-
- * **POP2, POP3, **APOP, **RPOP, **IMAP2bis, **IMAP4 support.
-
- ** Support for Kerberos user authentication (either MIT or Cygnus).
-
- ** Host is auto-probed for a working server if no protocol is
- specified for the connection. Thus you don't need to know
- what servers are running on your mail host in advance; the
- verbose option will tell you which one succeeds.
-
- ** Delivery via via SMTP to the client machine's port 25. This
- means the retrieved mail automatically goes to the system
- default MDA as if it were normal sender-initiated SMTP mail.
-
- ** Configurable timeout to detect if server connection is dropped.
-
- ** Support for retrieving and forwarding from multi-drop mailboxes
- that is guaranteed not to cause mail loops.
-
- ** Support for secure use with ssh.
