there is another reason than "not liking regular expressions".

RFC822 allows for continuation lines:

SUBJECT: this is my really long long long long long subject line from a galaxy
  far far far far far away

So even if you used a regex to match re.compile(r'(\w+):(.+)') you would still
miss the continuation line.  So you almost need a preprocessor which
concatenates lines if there is a continuation and when the line is finished
parse it.  Look at the rfc822 module for a better approach and to avoid
reinventing the wheel.
