rfc822

Problem / Question There is a database of bot information that I would like to parse. It is said to be similar to RFC822 messages . Before I re-invent the wheel and write a parser of my own, I figured I would see if something else was already available. I stumbled across imap_rfc822_parse_headers() , which seems to do exactly what I want. Unfortunately, the IMAP extension is not available in my environment. I have seen many alternatives online and on Stack Overflow. Unfortunately, they are all built for e-mail and do more than I need... often times parsing out an entire e-mail and handling

Python's email module is great for parsing headers. However, the To: header can have multiple recipients, and there may be multiple To: headers. So how do I split out each of the email addresses? I can't split on the comma, since the comma can be quoted. Is there a way to do this? Demo code: msg="""To: user1@company1.com, "User Two" <user2@company2.com", "Three, User <user3@company3.com> From: anotheruser@user.com Subject: This is a subject This is the message. """ import email msg822 = email.message_from_string(msg) for to in msg822.get_all("To"): print("To:",to) Current output: $ python x.py

How can I elegantly print the date in RFC822 format in Perl? use POSIX qw(strftime); print strftime("%a, %d %b %Y %H:%M:%S %z", localtime(time())) . "\n"; The DateTime suite gives you a number of different ways, e.g.: use DateTime; print DateTime->now()->strftime("%a, %d %b %Y %H:%M:%S %z"); use DateTime::Format::Mail; print DateTime::Format::Mail->format_datetime( DateTime->now() ); print DateTime->now( formatter => DateTime::Format::Mail->new() ); Update: to give time for some particular timezone, add a time_zone argument to now(): DateTime->now( time_zone => $ENV{'TZ'}, ... ) It can be done

I know how to do this the other way around... it would be: >>> dt.rfc822() 'Sun, 09 Mar 1997 13:45:00 -0500' In [1]: import rfc822 # This only works for python 2 series In [2]: rfc822.parsedate_tz('Sun, 09 Mar 1997 13:45:00 -0500') Out[2]: (1997, 3, 9, 13, 45, 0, 0, 1, 0, -18000) in python3 parsedate_tz has moved to email.utils >>> import email.utils # this works on Python2.5 and up >>> email.utils.parsedate_tz('Sun, 09 Mar 1997 13:45:00 -0500') (1997, 3, 9, 13, 45, 0, 0, 1, -1, -18000) As of python 3.3 there is email.utils.parsedate_to_datetime(date) >>> from email.utils import parsedate_to

Given an RFC822 message in Python 2.6, how can I get the right text/plain content part? Basically, the algorithm I want is this: message = email.message_from_string(raw_message) if has_mime_part(message, "text/plain"): mime_part = get_mime_part(message, "text/plain") text_content = decode_mime_part(mime_part) elif has_mime_part(message, "text/html"): mime_part = get_mime_part(message, "text/html") html = decode_mime_part(mime_part) text_content = render_html_to_plaintext(html) else: # fallback text_content = str(message) return text_content Of these things, I have get_mime_part and has_mime
