(Version 6.4 of 02/12/93) Multi-token class matches. IDA implementation is simple, but too stupid. RFC 931 validation. Database (keyed lookup) locking. Find a good test suite and include in the distribution. cf/cf/Makefile.dist (Nakamura Motonori ) Include a "Default MX" that always sorts lowest -- allows you to direct anything that cannot be sent immediately to a centralized site. (Nakamura Motonori ) If there is a TEMPFAIL anywhere during sending of email (specifically after a DATA), try the next MX host before giving up. WIN/3B support (non-atomic rename, no h_addr_list, others?) (Bruce Lilly )
