17 <H1 ALIGN=CENTER>Fetchmail Feature List</H1>
22 Fetchmail running in daemon mode now restarts itself quietly when the
25 <LI>Following recent court decisions and changes in U.S. federal
26 regulatory policy, hooks for Secure Sockets Layer (SSL) are now part
27 of the main fetchmail distribution. The distribution still contains
28 no actual cryptographic code.
30 <LI>NTLM support, so fetchmail can query Microsoft Exchange servers.
32 <LI>Expunge option can now be used to break POP3 retrieval into subsessions.
34 <LI>Support for AUTH=CRAM-MD5 under IMAP, a la RFC2195.
39 <LI>The interface and monitor options now work with freeBSD.
41 <LI> Fetchmail now sends RFC1894-conformant bouncemail on SMTP and LMTP errors.
43 <LI> Full support for LMTP according to RFC2033.
45 <LI> True multi-language support using GNU gettext.
47 <LI> Support for use of HESIOD with Kerberos.
49 <LI> The --bsmtp option supports recording fetched mail as a BSMTP batch.
51 <LI> The --limit option can now be used in daemon mode, with oversized-message
52 notifications being mailed to the calling user.
54 <LI> Configurable support for the
55 <a href="http://www.demon.net/services/mail/sdps-tech.html">SDPS extensions</a>
56 in <a href="http://www.demon.net/">www.demon.net</a>'s POP3 service.
58 <LI> There is now an interactive GUI fetchmail configurator, fetchmailconf.
60 <LI> Code is 64-bit clean and Y2K-safe.
62 <LI> Automatically decodes armored 7-bit MIME into 8 bits (this can be
65 <LI> You can specify which SMTP error is recognized as a spam block.
67 <LI> Support for Kerberos V authentication.
69 <LI> Support for IMAP-OTP authentication using Craig Metz's patches
72 <LI> Support for IPv6 (using glibc or Craig Metz's inet6-apps library).
74 <Li> Support for IPSEC (using Craig Metz's inet6-apps library).
76 <LI> Support for IMAP with RFC1731-conformant GSSAPI authentication.
78 <LI> Fixed and verified support for Cyrus IMAP server, M$ Exchange,
81 <LI> Support for responding with a one-time password when a POP3 server
82 issues an RFC1938-conforming OTP challenge.
84 <LI> Support for Compuserve's RPA authentication protocol for POP3
85 (not compiled in by default, but configurable).
90 <LI> Support for IMAP RFC 1731 authentication with Kerberos v4.
92 <LI> Support for multiple-folder retrieval in a single session
95 <LI> Following SMTP 571 response to a From line, fetchmail no longer
96 downloads the bodies of spam messages.
98 <LI> Support for a `hunt list' of SMTP hosts.
100 <LI> Support for ESMTP 8BITMIME and SIZE options.
102 <LI> Support for ESMTP ETRN command.
104 <LI> The stripcr & forcecr options to explicitly control carriage-return
105 stripping and LF->CRLF mapping before mail forwarding.
110 <LI> Support for secure use with ssh.
112 <LI> Mailserver passwords can be parsed out of your .netrc file.
114 <LI> When forwarding mail via SMTP, fetchmail respects the 571
115 "spam filter" response and discards any mail that triggers it.
117 <LI> Transaction and error logging may optionally be done via syslog.
119 <LI> (Linux only) Security option to permit fetchmail to poll a host
120 only when a point-to-point link to a particular IP address is
123 <LI> RPOP support (restored; had been removed in 1.8).
126 <H2>2.0 and earlier versions:</H2>
128 <LI> Support POP2, APOP, RPOP, IMAP2, IMAP2bis, IMAP3, IMAP4, IMAP4rev1. .
130 <LI> Support for Kerberos V4 user authentication (either MIT or Cygnus).
132 <LI> Host is auto-probed for a working server if no protocol is
133 specified for the connection. Thus you don't need to know
134 what servers are running on your mail host in advance; the
135 verbose option will tell you which one succeeds.
137 <LI> Delivery via SMTP to the client machine's port 25. This
138 means the retrieved mail automatically goes to the system
139 default MDA as if it were normal sender-initiated SMTP mail.
141 <LI> Configurable timeout to detect if server connection is dropped.
143 <LI> Support for retrieving and forwarding from multi-drop mailboxes
144 that is guaranteed not to cause mail loops.
146 <LI> Large user community -- fetchmail has a large user base (the
147 author's beta list includes well over two hundred people). This
148 means feedback is rapid, bugs get found and fixed rapidly.
150 <LI> Carefully written, comprehensive and up-to-date man page describing
151 not only modes of operation but also how to diagnose the most
152 common kinds of problems and what to do about deficient servers.
154 <LI> Rugged, simple, and well-tested code -- the author relies on it
155 every day and it has never lost mail, not even in experimental
156 versions. (In the project's entire history there has only been
157 one recorded instance of lost mail, and that was due to a quirk
158 in some Microsoft code.)
160 <LI> Strict conformance to relevant RFCs and good debugging options.
161 You could use fetchmail to test and debug server implementatations.
163 <LI> For anybody who cares, fetchmail is Y2K safe.
166 <H2>Features in common with other remote-mail retrieval programs:</H2>
168 The other programs I have checked include fetchpop1.9, PopTart-0.9.3,
169 get-mail, gwpop, pimp-1.0, pop-perl5-1.2, popc, popmail-1.6 and upop.<P>
172 <LI> Support for POP3.
174 <LI> Easy control via command line or free-format run control file.
176 <LI> Daemon mode -- fetchmail can be run in background to poll
177 one or more hosts at a specified interval.
179 <LI> From:, To:, Cc:, and Reply-To: headers are rewritten so that
180 usernames relative to the fetchmail host become fully-qualified
181 Internet addresses. This enables replies to work correctly.
182 (Would be unique to fetchmail if I hadn't added it to fetchpop.)
184 <LI> Message and header processing are 8-bit clean.
