Sometimes it's time to take a moral stand and refuse to encourage bad ideas.... (OK, it's been a too-long week already. I'll quit ranting. ;) (string-match "/[GS]=\\([-a-zA-Z0-9._]+\\)[^!＠%]+\\([-a-zA-Z0-9!(a)%._]+\\) (1) (2) (2) (1) If we're going to try to support X.400 addresses, is there a reason to restrict it to some Motorola subset? I'm not *positive*, but I suspect that extending the string-match from "/[GS]=\\" to "/[A-Z]+=\\" will catch all the c= and prmd= and all that stuff too. At least it looks like this code only deals with the X.400 variants that smash ' ' to '_' - if we had to deal with quoted whitespace, the code would be a lot worse. (2) To support more general X.400, we'd have to accept something like /c=us/prmd=foo_mail/o=bar/ou=baz/cn=joe_random(a)some.x-400.gate - but that would require having '/' in the regexp as well... (3) I'm also not sure about the _ here - this looks like it will accept a _ in a hostname, which is a no-no. Of course, the _ *would* be OK after a ! or % since it would still be in the rfc822 local-part. I guess it's no sin accepting a broken hostname, as long as we correctly focus on a purported address and not a comment field. And lest I be accused of X.400 bashing, I'll leave you all with this gem of an address, straight from RFC822, section 3.1.4: So, for example, the folded body of an address field ":sysmail"＠ Some-Group. Some-Org, Muhammed.(I am the greatest) Ali ＠(the)Vegas.WBA is analyzed into the following lexical symbols and types: :sysmail quoted string ＠ special Some-Group atom . special Some-Org atom , special Muhammed atom . special (I am the greatest) comment Ali atom ＠ atom (the) comment Vegas atom . special WBA atom The canonical representations for the data in these addresses are the following strings: ":sysmail"＠Some-Group.Some-Org and Muhammed.Ali(a)Vegas.WBA Yes, it's valid. Gaak. ;) http://public.yahoo.com/~jfriedl/regex/code.html if you're masochistic. ;) /Valdis
