Notes for use of NTLM authentication support with JavaMail ---------------------------------------------------------- Thanks to the efforts of Luis Serralheiro, JavaMail now suports the use of Microsoft's proprietary NTLM authentication mechanism. This support within JavaMail is now derived from the NTLM support in the JDK and included directly in JavaMail, with no external dependencies. This release of JavaMail was tested with Microsoft Exchange 5.5 and 2007. The SMTP and IMAP providers support the use of NTLM authentication. The following properties can be used to configure the NTLM support: mail..auth.ntlm.domain The NTLM authentication domain. mail..auth.ntlm.flags NTLM protocol-specific flags. (not currently used) See http://curl.haxx.se/rfc/ntlm.html#theNtlmFlags for details. NOTE: This capability is very new and has NOT been thoroughly tested. Please send any feedback or bug reports to us at [email protected]. WARNING: This support, and the APIs and properties used to control it, should be considered EXPERIMENTAL. They may be changed in the future in ways that are incompatible with applications using the current APIs and properties.
