-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 2.0:
-
- ** Support for secure use with ssh.
-
- ** Mailserver passwords can be parsed out of your .netrc file.
-
- ** When forwarding mail via SMTP, fetchmail respects the 571
- "spam filter" response and discards any mail that triggers it.
-
- ** Transaction and error logging may optionally be done via syslog.
-
- ** (Linux only) Security option to permit fetchmail to poll a host
- only when a point-to-point link to a particular IP address is up.
-
- ** RPOP support is back.
-
-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 **.
+fetchmail supports standard all mail-retrieval protocols in use on the
+Internet: POP2, POP3 (including POP3 with RFC1938 one-time passwords),
+RPOP, APOP, KPOP, Compuserve's POP3 with RPA, Microsoft's NTLM, Demon
+Internet's SDPS, all flavors of IMAP (including IMAP4rev1 with RFC1731
+Kerberos v4 or GSSAPI authentication or CRAM-MD5 authentication), and
+ESMTP ETRN. Fetchmail also supports end-to-end encryption with OpenSSL.
