[OT] Hardware

Hi I know this is slightly OT, but I'd appreciate any responses. I intend to set up a box running SUSE, sendmail, and probably something like Majordomo. The sole purpose of the box will be to act as a mailing list server. All the mailing lists will be announcement lists, sending out about 100 000 messages a month (email newsletters etc). Are there any recommendations for the kind of specs a box like this should have? Thanks Evan Morris evan@exclusivebooks.com Tel: +27 11 792 2777 Fax: +27 11 792 2711 Cell: +27 82 926 3630
