The Simple Authentication and Security Layer (SASL) provides a common framework for authentication in protocols like IMAP and SMTP. RFC 4422 defines the basic framework, and separate RFCs define authentication mechanisms within this framework.
Archiveopteryx implements the following SASL authentication mechanisms:
PLAIN (RFC 2595) is like the classic login method: The client sends login and password as cleartext, and the server checks them.
ANONYMOUS (RFC 2245) provides anonymous logins, if desirable. This is disabled by default.
CRAM-MD5 (RFC 2195) is a widely supported challenge/response method.
LOGIN is broadly similar to PLAIN, except that it's slower and not standard.
