[Mailman-Users] A problem

[IslamWay.com]

Hi,   first of all I'd like to than you for such a great service (MAIL-MAN).   I've installed Mailman in my server, and put all the Mailing list for our team workers in it. However I'm facing a problem now with dumping the emails of the mailing list into a text file so I can save it as a backup. My main mailing list consists of 65,000 emails and the roster service from the http didn't work.   Is there is a way I can dump my database of connections into a text file (with addres per line) ?   Please let me know
