Design and Implementation of Highly Scalable Internet E-mail Systems
Brad Knowles
Topic: Email/DNS/Spam
Audience: Intermediate/Advanced
Description:
Depending on the amount of time available, relevant papers in the field are reviewed and summarized for the benefit of the audience. This portion of the talk can be shortened, as appropriate.
Afterwards, the POP3 protocol is analyzed for typical behaviour and methods that can be applied to improve its performance and scalability. This is then contrasted with the IMAP protocol. A set of Best Current Practices are then outlined.
Some statistics are given for one sample POP3-based Internet e-mail system serving almost 300,000 customers, and then the functional and detailed architectures are presented for a replacement mail system designed to scale to at least a million customers, with relatively easy extension to tens of millions of customers.
Prerequisites:
People should understand how their mail system works. They should understand what an MTA is, how it functions when receiving a mail message, how it hands the message off to the local delivery agent (LDA), how the LDA then stores this message into a mailbox, and then how the user logs in to retrieve their mail.
History:
LISA 2000, the Winter 2001 UKUUG conference, and the unix.nl conference recently sponsored by Snow BV (2001/09/14).
