This is supported by procmail.  It expands to any of the possiblities in
the error message below.  

procmail: No match on "(^((Original-)?(Resent-)?(To|Cc|Bcc)|
(X-Envelope|Apparently(-Resent)?)-To):(.*[^a-zA-Z])?)
first.last+marker at example.com"

On the other hand, using '^To:.*first.last...' would match only a line
beginning 'To:...' and wouldn't match any of the others.  In any case it
turns out the '+' has a special meaning and needs to be escaped.

* ^TOfirst.last\+marker at example.com

works nicely...
