Well, the ones suggested so far have been: Free: mercury mail (http://www.pmail.com). IMP (http://www.horde.org/imp) LSMTP from LSoft Not Free: IMail from Ipswitch (www.ipswitch.com) DMail's OK ( http://netwinsite.com ) Xmail http://www.xmailserver.org (Free? ) However, I haven't seen anyone mention MailEnable yet, so you might want to check it out. The standard version is free, provides SMTP and POP3, as well as a list server. Find it at <http://www.mailenable.com> Regards Dave
