28-----------------

30The use, supply or promotion of Exim for the purpose of sending bulk,
31unsolicited electronic mail is incompatible with the basic aims of the program,
32which revolve around the free provision of a service that enhances the quality
33of personal communications. The author of Exim regards indiscriminate
34mass-mailing as an antisocial, irresponsible abuse of the Internet.

37INCORPORATED CODE
38-----------------

40A number of pieces of external code are included in the Exim distribution.
41
42 . Regular expressions are supported in the main Exim program and in the
43 Exim monitor using the freely-distributable PCRE library, copyright (c)
44 2003 University of Cambridge. The source is distributed in the directory
45 src/pcre. However, this is a cut-down version of PCRE. If you want to use
46 the PCRE library in other programs, you should obtain and install the
47 full version from ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre.

50 . Support for the cdb (Constant DataBase) lookup method is provided by code
51 contributed by Nigel Metheringham of Planet Online Ltd. which contains
52 the following statements:

62 This code implements Dan Bernstein's Constant DataBase (cdb) spec.
63 Information, the spec and sample code for cdb can be obtained from
64 http://www.pobox.com/~djb/cdb.html. This implementation borrows some code
65 from Dan Bernstein's implementation (which has no license restrictions
66 applied to it).
67 _________________________________________________________________________
68
69 The implementation is completely contained within the code of Exim. It
70 does not link against an external cdb library.
71
72 . Client support for Microsoft's "Secure Password Authentication" is pro-
73 vided by code contributed by Marc Prud'hommeaux. Server support was
74 contributed by Tom Kistner. This includes code taken from the Samba
75 project, which is released under the Gnu GPL.
76
77
78 . Support for calling the Cyrus "pwcheck" and "saslauthd" daemons is
79 provided by code taken from the Cyrus-SASL library and adapted by
80 Alexander S. Sabourenkov. The permission notice appears below, in
81 accordance with the conditions expressed therein.
