Over a decade of system administration experience, with recent focus on Linux, DNS, and email.
Well-versed in DNS as well as email protocols, along with anti-spoofing/anti-spam techniques -- including but not limited to DNSSEC, DKIM, SPF, ADSP, and DMARC. Active participant in the development and testing of future Internet mail standards as well as ISC BIND product features (primarily related to DNSSEC).
At work I manage outgoing email using Message Systems Momentum and internal/external DNS using BIND for a large and well-known company. My primary function at work however is tier 3 support for all systems related issues for the live production site, including but not limited to managing Solaris+Veritas+Oracle clusters, LAMP stack servers, F5 & Netscaler load balancers.
I am a member of several messaging anti-abuse coalitions including MAAWG and OTA, and am very active in that forum.
