NAME
Email::Blaster - Scalable Mass Email System
SYNOPSIS
Generally, don't use this module from your code. Use the supplied scripts instead.
DESCRIPTION
Email::Blaster is the latest in a long, long line of mass-emailer systems I have written since 2002.
This version has many features.
Clustering Support
Uses memcached and libevent to do the heavy lifting.
Testing mode.
Send a few messages to yourself before you turn on the firehose.
Domain-based throttling with hourly limits.
Never get blacklisted again because of email flooding too quickly from your network.
Configurable (and subclassable) behaviors and components.
If configuration alone doesn't get you what you want, you can always subclass something (i.e. MailSender or MaillogWatcher) to get the desired behavior.
Scales Out Well (Clustering).
Designed to spread the work out across many, many, many servers. If your email list has 1Million subscribers, you could *reliably* send your messages to them in a matter of minutes.
Add more servers, get more capacity and throughput.
Event handlers (in serial).
Handle server-level events with a simple plugin. Events like server startup and shutdown, the start or end of a transmission, etc.
More details to follow.
