Postfix header_checks using regexp and multiple lines

I'm posting this because it wasn't easy or obvious how this would be accomplished and the man page leaves it to guesswork.

Multi-line body_checks

Example 1
/<img src="cid:part.*"/
/height="430"/ REJECT

Example 2
/<img src="cid:part.*"/
/height="430" width="430" align="center" border="0">/ REDIRECT junkbox@domain.com
