Proofpoint Essentials Data Center Information

 Special Note:

*Use only the data center that was assigned to your company. Failure to use the correct data center will result in lost mail due to rejections.

*Please ensure you add our IPs to your firewall's white list. If your firewall runs a blacklist, this will result in dropped/deferred connections if our IPs are not allowed through, hence delaying email.
