\& Generates a list of all the recipients of email from any senders

\&
\& As a convenience, pftobyfrom tries to intelligently determine how to
\& handle regexp meta\-characters. If it\*(Aqs passed a search expression
\& that does NOT contain meta\-character escapes ("\e"), it will assume
\& that "." and "+" are literals, and will escape them for you. In the
\& example above, the "." in the FQDN part of the search term would\*(Aqve
\& been automatically escaped for the user. Likewise:
\&
\& pftobyfrom username+foo@example.com /var/log/maillog
\&
\& would have the "+" and "." escaped. If you wanted to find all
\& plussed senders for "username," you\*(Aqd have to do:
