Biology Lines: 19 Issue number one: % has no precedence at all. If you change that, I promise you that mail will be lost. The easiest and most correct way to deal with % is not to. If you just pass it along when you see it, the right thing will happen - ESPECIALLY if you are a UUCP site. If you insist on checking for it, let it be the lsat thing you check before final delivery (thus giving it lowest preference). There are enough routing characters in this world, thank you! End of tirade. Issue number two: Route addrs are obsolete. It is legitimate for an implementation to short circuit right to the address after the colon. Because the mail specification designed to be an end to end protocol, ``routing'' other than through the use of MX records is strongly discouraged. -- Eliot Lear [lear@turbo.bio.net]
