Is is -a framework for adding authentication and encryption to network protocols. -It is described in IETF RFC 2222. - -This release of nmh supports SASL for SMTP. The SASL support is -implemented using the Cyrus-SASL library. This library can be found at -ftp://ftp.andrew.cmu.edu/pub/cyrus-mail. Obviously, SASL support only -works if you use the SMTP mail transport. - -This release of NMH only supports "Version 2" of the Cyrus SASL library. -It should work with any newer Cyrus SASL release, but it was tested with -Cyrus SASL 2.1.22. In particular, the CRAM-MD5 and GSSAPI (Kerberos 5) -mechanisms were tested. Older versions of Cyrus-SASL had a bug which -could manifest when negotiating encrypting depending on the encryption -type you used, so a newer version of Cyrus-SASL is recommended. - -Currently, security layers ("encryption" in SASL-speak) are supported -for SMTP. This means that if your SMTP server _and_ the selected SASL -mechanism supports it, client-server communications will be encrypted. -In theory this should work with any SASL mechanism that supports security -layers; it has only been tested with the GSSAPI mechanism. - -If you are curious as to whether or not your communications are actually -encrypted or not, you can use the -snoop flag to the SMTP utilities. -Communication that is encrypted is preceeded by an (encrypted) or -(decrypted), depending on the direction of communication. - -If you would like to use the GSSAPI SASL mechanism (Kerberos V), you -should read very carefully the documentation that comes with Cyrus-SASL, -specifically the GSSAPI documentation. Getting the GSSAPI plugin to -work correctly with SASL can be "interesting" to say the least. -- 1.7.10.4
