Is there any particular reason why you're using regular expressions
for this? You are already iterating over the lines in your first for
loop. You can just make the tests you need there.
for line in file:
if 'Recvd-Content' in line or 'Published-Content' in line:
<do something with the line>
Your regular expression seems like it will match a lot more strings
than the two you mentioned earlier.
Also, 'file' is a python built-in. It will be best to use a different
name for your variable.
