You could instead grab the whole boundary parameter in one step, then strip the quotes after that:
Cary, thanks for the input... How do I get the literal ctrl-M into the bracket expression? Type ctrl- M into nano? It would make the regexp seem to break across a line? The second recip looks like a simple way to get rid of the quotes if they're there.
:0 H # NOTE: The ^M in the RE needs to be a literal carriage # return, not the two separate characters ^ and M. # Procmail does not support control-character escapes. # This is necessary because some mail comes in with CR-LF # line endings, and you don't want the CR included in the match. * ^Content-Type:\W*\<multipart.*\<boundary=\/[^; ^M]* { TESTVAR = $MATCH
:0 * TESTVAR ?? "\/[^"]* { TESTVAR = $MATCH } }
