 Python Gateway Script from news to mail and vice versa.

 It is intended to be a full SMTP/NNTP rfc compliant gateway
 with whitelist manager.

 You will probably have to install a mail-transport-agent and/or
 news-transport-system package to manage SMTP/NNTP traffic.

 MTA is needed for mail2news service, since mail have to be
 processed on a box where pyg is installed. You can use a remote
 smtpserver for news2mail.

 News system is useful but not needed, since you can send articles to a
 remote SMTP server (ie: moderated NG) where is installed pyg, otherwise you
 will need it.

 It refers to rfc 822 (mail) and 850 (news).
