Description:
This is easily demonstrated by using either tool to search the "Received" headers, as virtually all messages will have several of them. I figured out this can be worked around via magrep "*:regex" to search all the headers so it's not a show stopper. I realize this may be intentional, but if so I don't believe it is clearly documented in the respective man pages (unlike mhdr which has -M option).
