Hello. I am trying to convert a mailing list community about environmental protection to the website using Drupal 5.4. Mailing list is always my favour but for non technical groups this poses problem like

1. contents are not properly categorized and have right tags attached; 2. discussion are sometimes not followed well due to some user are not guru in using email software; 3. big attachment is not practical for a lot of subscribers. 4. ....

My effort to move user to the website is:

1. Try to find a way to integrate mailing list to the forum on Durpal. Emails sent to mailing list automatically appear on Drupal. Currently I didn't find a technical way to do so, can you provide some hints? 2. Try to make drupal forum sends email notification to everybody. Currently I found drupal only sends notification of forum message to those who subscribed the thread of discussion, this is not very useful in our case, in our case it's useful to send to even those who have not subscribed the thread of discussion also receive notifications. That's because it had been like this for 5 years and user feel it more comfortable than only receive subscribed threads notifications. There are too many lurking people that we don't want to loose by moving to the website. By doing so we ensure the user posting on the website forum does not feel lurkers would miss their message. Hints on how to make it happen?

Thank you very much in advance!
