This unique technology keeps receiving mail, and delivering it
to users, even if one of the two servers crashes (or one of the
two data centers is put out of commission -- hence "bomb-proof").
Standard features of all e-mail services include both virus- and
spam-filtering, use of IMAP and POP3 mail protocols, IMAP and POP3
over encrypted SL connections, full featured webmail access from
any browser, support for large attachments, and surprisingly low
disk storage costs.
