Anders Saaby, CTO, One.com explains, “Due to One.com’s high growth rate, we needed to upgrade our existing email delivery and security infrastructure to a newer solution that scaled better in terms of performance and maintenance.

One.com typically develop their own software and systems as this enables them to offer truly differentiated services with many unique features, at very competitive prices. This usually rules out many commercial products, as they cannot properly support and integrate into One.com’s sophisticated and highly customized platforms.

“We researched and evaluated many email security and delivery platforms against our requirements,” Saaby continued. “We finally settled on Halon email platform based on price, performance, ease of use, flexibility, multitenancy support with security and its ability to scale on demand.”

Halon’s highly integrated and comprehensive platform now comprises One.com’s entire email delivery infrastructure; except for email storage and web mail.

It’s a flexible and scriptable email engine, designed to be run as part of a fault tolerant and linearly scalable cluster that integrates with surrounding modules and infrastructure. This highly differentiated platform enables demanding organizations like hosting providers and MSPs to implement ideal solutions for their specific needs.

On the inbound side, clusters of Halon nodes have replaced several layers of One.com’s email gateways. The clusters perform;

  • IP reputation
  • recipient verification
  • anti-spam and antivirus
  • filtering
  • both aliases and external forwards with SRS
  • auto replies
  • backup/replay
  • routing to the email storage servers over LMTP

all according to a REST API that One.com wrote. The outbound cluster integrates with the same API for SASL authorization, relay permissions and rate metrics, and ensures excellent deliverability.
