ATWILL, LLC
JACKSONVILLE, FLORIDA

ATWILL, LLC is an innovative technology company founded in Jacksonville, Florida. Established on October 28, 2007, with a focus on software development for email systems and message transfer agents (MTAs), ATWILL has built a reputation for crafting high-performance solutions. The company's development journey commenced over two decades ago at Quiksoft Corporation, where foundational work on the EasyMail product line laid the groundwork for its advanced SMTP, POP3, IMAP4, and mail storage capabilities. ATWILL's flagship offering began with SMTPExpress, a pioneering C++ 32-bit message transfer agent designed to meet the demands of high-volume email dispatch. The Pro version enhanced this by incorporating high IO performance optimizations and tailored delivery rules for email throttling across domains. Building on these successes, ATWILL developed the next generation MTA through an innovative blend of C++ and .Net technologies. This hybrid approach leveraged the strengths of both languages to provide superior performance and maintainability—an accomplishment facilitated by using inline assembly within its core engine. Headquartered at 9001 Forest Acres Lane in Jacksonville, FL, ATWILL continues to progress with an official website at [atwill.com](http://www.atwill.com). The company is registered under the Florida Business License with the filed number L07000110381. As of January 8, 2024, ATWILL's latest annual report pertains to its operations in the year 2024, further affirming its ongoing industry presence and operational transparency as per its Fei Number 261444892.
