Wong is the founder of (one of the first hosted email services) and is also the creator of the Sender Policy Framework (SPF) protocol used for spam control.
Another alternative is Stubmail, a variant of IM2000 developed by Meng Weng Wong and Julian Haight. Another limitation of SMTP is that users of hosted email services (such as Yahoo Mail, Gmail, Comcast, etc.) cannot easily migrate to another email service without changing their email address, because SMTP email addresses are coupled to domains.Īs a result, alternative email transport protocols have been developed such as IM200 which is a “push” email protocol proposed by D. Another limitation of SMTP is that it lacks built-in methods for enabling a sender to track the delivery of a message through the internet, and confirm the receipt of a message by the recipient. This technique, known as ‘spoofing’, is often exploited by spammers when sending large numbers of unsolicited and often malicious ‘phishing’ email messages.Īnother limitation of SMTP is that it lacks built-in methods for enabling end-to-end encryption of messages, and for digital signing of messages. Because of this limitation, malicious senders are able to construct email messages appearing to originate from senders other than themselves. Many users feel that SMTP is unreliable because of this problem, and it is not uncommon for people in the technical community to express that SMTP is now ‘broken’ for this reason.Īnother limitation of SMTP is that SMTP lacks a built-in method for authenticating the sender of a message. Spam filters are known to routinely flag legitimate messages as spam erroneously, resulting in these messages not being delivered to their intended recipients, many times unbeknownst to both the senders and the recipients of these messages. However, while ahead of its time in 1982, SMTP has a number of inherent limitations which hinder its usability in today's world.įirst and foremost, the widespread problem of junk email (known as ‘spam’) and consequently the use of spam filters to combat spam, have resulted in SMTP being unreliable.
BITMESSAGE EMAIL SOFTWARE
Impressively, now more than 30 years later, SMTP largely as defined in RFC821, is still widely used by email software and systems as the standard protocol for transporting email. The specification for SMTP was originally described in a publication known as RFC821 in 1982. The protocol generally used by email software and systems to deliver email messages from senders to recipients through a packet-switched network is known as SMTP (Simple Mail Transport Protocol).
This present invention relates generally to electronic communications and, more particularly, to a system and method for enabling users to migrate from the legacy SMTP protocol to an alternative email protocol, e.g., Bitmessage protocol.įollowing the widespread adoption of the Internet, electronic mail is now a widely used method for communicating written information, used by billions globally. 11, 2013 entitled SYSTEM AND METHOD FOR SMTP AND ALTERNATIVE EMAIL PROTOCOL INTEROPERABILITY and all of whose entire disclosures are incorporated by reference herein. 28, 2014, which in turn claims the benefit under 35 U.S.C. national phase application claims the benefit under 35 U.S.C.
