Bowie, thank you what about the case of non numeric WHATEVERLEGALCHARS, ie any legal character in a domain name replacing the number series? i.e. header __LOCAL_MAILENGINE ALL =~ /mailengineWHATEVERLEGALCHARS\.com/i i do understand that it would be similar to a catchall, yet still interested in knowing in cases of funkiness ;-) - rh
