Answer 1

Try like this

INSERT INTO `mailinglist_archives`
              (`recipients`) 
               SELECT GROUP_CONCAT(`email`)
               FROM mailinglist

Answer 2

You can do this with GROUP_CONCAT :

INSERT INTO `mailinglist_archives`
          (`recipients`) 
           SELECT GROUP_CONCAT(`email`)
           FROM mailinglist

That said, this is not a good idea; you should normalize your database, rather than storing lists in columns.

Edit to address comment:

You can combine these two queries:

$query0 = "INSERT INTO mailinglist_archives (subject, message, datesent) VALUES ('$subject', '$ckcontent', '$timestamp')";
$query01 = "INSERT INTO mailinglist_archives (recipients) SELECT GROUP_CONCAT(email) FROM mailinglist";

like this:

INSERT INTO mailinglist_archives (subject, message, datesent, recipients)
SELECT '$subject', '$ckcontent', '$timestamp', GROUP_CONCAT(email) FROM mailinglist

Again, however, this will result in a (potentially very large) list in the recipients column. This will cause problems, sooner or later, so you are better off normalizing the data by creating a new table to match recipient ids and message ids.
