+fetchmail README
+================
-fetchmail is a free, full-featured, robust, well-documented remote
-mail retrieval and forwarding utility intended to be used over
-on-demand TCP/IP links (such as SLIP or PPP connections). It
-retrieves mail from remote mail servers and forwards it to your local
-(client) machine's delivery system, so it can then be be read by
-normal mail user agents such as elm(1) or Mail(1).
+Introduction
+------------
-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, Demon Internet's SDPS,
-all flavors of IMAP (including IMAP4rev1 with RFC1731 Kerberos v4 or
-GSSAPI authentication), and ESMTP ETRN.
+Fetchmail is a free, full-featured, robust, well-documented remote mail
+retrieval and forwarding utility intended to be used over on-demand TCP/IP
+links (such as SLIP or PPP connections). It retrieves mail from remote mail
+servers and forwards it to your local (client) machine's delivery system, so it
+can then be be read by normal mail user agents such as mutt(1), elm(1) or
+Mail(1).
-The fetchmail code was developed under Linux, but has also been
-extensively tested under 4.4BSD, AIX, HP-UX versions 9 and 10,
-SunOS, Solaris, NEXTSTEP, and OSF 3.2.
+Fetchmail supports all standard mail-retrieval protocols in use on the
+Internet: POP3 (including some variants such as RPOP, APOP, KPOP), IMAP4rev1
+(also IMAP4, IMAP2bis), POP2, IMAP4, ETRN, and ODMR. On the output side,
+fetchmail supports ESMTP/SMTP, LMTP, and invocation of a local delivery agent.
-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. It is reported to build and run
-under AmigaOS.
+Fetchmail also fully supports authentication via GSSAPI, Kerberos 4 and 5,
+RFC1938 one-time passwords, Compuserve's POP3 with RPA, Microsoft's NTLM, Demon
+Internet's SDPS, or CRAM-MD5 authentication a la RFC2195.
-A beta OS/2 port of fetchmail is available from Jason F. McBrayer at
-http://studentweb.tulane.edu/%7Ejmcbray/os2.
+Fetchmail supports end-to-end encryption with OpenSSL, do read README.SSL for
+details on fetchmail's configuration and README.SSL-SERVER for server-side
+requirements. NOTE! To be compatible with earlier releases, fetchmail 6.3's
+default behaviour is more relaxed than dictated by the standard - add options
+such as --sslcertck to tighten certificate checking.
-Fetchmail is Y2K safe.
+Portability
+-----------
-See the distribution files FEATURES for a full list of features, NEWS
-for detailed information on recent changes and NOTES for design notes.
+The fetchmail code was developed under Linux, but has also been extensively
+tested under the BSD variants, AIX, HP-UX versions 9 and 10, SunOS, Solaris,
+NEXTSTEP, OSF 3.2, IRIX, and Rhapsody.
-The fetchmail code appears to be stable and free of bugs affecting
-normal operation (that is, retrieving from POP3 or IMAP in single-drop
-mode and forwarding via SMTP to sendmail). It will probably undergo
-substantial change only if and when support for a new retrieval
-protocol or authentication mode is added.
+It should be readily portable to other Unix variants and Unix-like operating
+systems (it uses GNU autoconf). It has been ported to Cygwin, LynxOS and BeOS
+and will build there without special action. It has also been ported to QNX;
+to build under QNX, see the header comments in the Makefile. It is reported to
+build and run under AmigaOS.
