Project Overview

Over a decade ago, IT-supported Sun mail (MX) servers and their email inboxes that were had been hosted on-premises were migrated to Gmail.

After that migration, some hardware in the mail pipeline remained for security and mail routing reasons.

Google has since improved Gmail's security features (previously known as Postini), so we will no longer require the use of on-promises email security appliances (ESAs) is no longer required.

By eliminating the SMTP routing of email to these on-premises hardware (load-balancer and appliancesESAs), we gain the added benefit of increasing email will increase our email delivery's resiliency during events, such as PSPS, which could cause LBL data center power outages.

Previous to 7/11/20, emails sent to Existing lbl.gov (and some other domains) SMTP traffic routes to mailgate.lbl.gov (, along with a number of other domains, recipients routed to an on-premises load-balancerbalancer (mailgate.lbl.gov) before arriving at the Cisco ESAs/Ironports (fe3.lbl.gov or  or fe4.lbl.gov), which drop connections from mail servers with poor reputations and check remaining messages for spam, viruses before further routing messages to their final destination at Gmail or to LBNL Certified Mail Servers (aka Email Repositories).
