The reason why <I> never said anything about it is because it is a documented restriction, not a bug. For instance, please see: * Appendix B of the list owner's or site manager's manual, under "Subject-Tag=" * Chapter 6.1.1 of the site manager's manual, under "SET SUBJecthdr" * Chapter 5.3.6 of the list owner's manual, under "SET SUBJecthdr" I will admit that this behaviour does not appear to be documented in the release notes. However, I would have thought that being documented in four separate places in the formal documentation would have been sufficient... Nathan
