I have a usertest called "@from_to" which compares the contents of the "From:" field with the contents of the "To:" field and it doesn't use the EndOfHeader feature. In the Rules file I have the line: delete * @ from_to and in UserTests I have: DEF FN@from_to LOCAL user_return%, n$, i%, len% user_return% = FALSE IF k$ = "from" OR k$ = "to" THEN len% = LEN(d$) IF len% > 5 THEN n$ = d$ i% = INSTR(n$, "@"): IF i% > 0 THEN n$ = LEFT$(n$, i%-1) i% = INSTR(n$, "<"): IF i% > 0 THEN n$ = LEFT$(n$, i%-1) IF LEN(n$) > 4 THEN IF k$ = "from" THEN user_from$ = n$ ELSE user_to$ = n$ ENDIF IF user_to$ = user_from$ THEN user_return% = TRUE ENDIF ENDIF ENDIF =user_return% Of course I have to fiddle around resetting variables at the beginning of each message, but at least it does get triggered at the "right" header line. -- -
