[ALUG] Mail search that can find an exact date

I'm looking for an E-Mail search command that will find an *exact* date. I.e. I know the E-Mail I'm looking for has:- Date: 19 Jan 2010 15:30:24 However none of the mail search programs I've tried seems to be able to handle this, they all want to search for mails in a date range, usually with no time at all specified. I've only tried mairix and grepmail so far but it looks as if notmuch will have the same issues. I know I could simply use grep but that doesn't "know about" E-Mails so although it can find the specific E-Mail it can't show me the E-Mail body which is what I'm after. -- Chris Green
