No, see RFC-2822 section 3.6.4 It clearly says that a Message ID must be: \s "<" id-left "@" id-right ">" \s where you can more-or-less call the left & right parts: [\w\.-\?]{1,} (using perl reg-ex syntax, this is a slight oversimplification but true to the intent). So since your example is missing the required "@" in the middle, it isn't valid. -- Dave Funk University of Iowa <dbfunk (at) engineering.uiowa.edu> College of Engineering 319/335-5751 FAX: 319/384-0549 1256 Seamans Center Sys_admin/Postmaster/cell_admin Iowa City, IA 52242-1527 #include <std_disclaimer.h> Better is not better, 'standard' is better.
