I have a subscription to a public mailing list, but I would prefer to read the messages in my twitter stream rather than in my inbox.
My idea was to forward the e-mails to a blogging system which supports auto-posting to twitter. Both posterous.com and wordpress.com can do that, but they only accept posting via e-mails from known (and registered) addresses.
Do you have any other idea? Can you think of another approach? Did I overlook something?
Tweetymail is also no (usable) solution. When wordpress.com or posterous post to twitter, the tweet contains the mail's subject line and a link to the post where one can read the body of the mail. Tweetymail uses a similar concept, but removes all the newlines in the body text, which renders the body (imho) so badly readable, that I rather don't want to use their service.
