I think I found the answer after digging through the code.

It appears that the Python re module is used. Does this mean we can use the 
Python re module extensions in "Hold posts"?

for line in string.split(self.bounce_matching_headers, '\n'):
     stripped = string.strip(line)
     if not stripped or (stripped[0] == "#"):
         # Skip blank lines and lines *starting* with a '#'.
         continue
     else:
         try:
             h, e = re.split(":[ \t]*", stripped, 1)
             try:
                 re.compile(e)
                 all.append((h, e, stripped))
             except re.error, cause:
                 # The regexp in this line is malformed -- log it
                 # and ignore it
                 syslog('config',
                        '%s - bad regexp %s [%s] '
                        'in bounce_matching_header line %s'

return all
