It's even more neat than that. One of the purposes (maybe the original purpose?) is to use IP addresses in SMTP fields: define(`SMART_HOST', `[192.168.1.1]')dnl It also works (should work, anyway) in mail address fields: To: discuss@[216.235.254.231] for example. That will almost certainly cause all sorts of problems since you're not getting MX processing and any filtering based on domain part will probably fail, but it is a syntactically valid mailbox per RFC 2822. -- Rich P. _______________________________________________ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
