Email delivery service market

Send reputation and new IPv4 addresses

SMTP was allocated 4,096 portable IPv4 addresses, a big enough supply of IP addresses for all its customers. The move will force SMTP.com to use these new IP addresses for sending. The IP based send reputation built by SMTP will be lost, and needs to be rebuilt at the new hosting center.

SMTP.com is locating its new data center at the Hurricane Electric facility in Freemont, California, with alternative direct routing over the XO Communications fiber network. CISCO and Dell will be providing the primary router and server hardware.
