RooJs.com: How to spam in PHP..
On RooJs.com there's a recent post from Alan Knowles looking at how to spam in PHP. No, nothing malicious - it's more about scalability in sending emails from PHP applications.
The reason this has been relivant in the last two weeks is two fold, first off, my slow and sometimes painfull rewrite of mtrack has got to the point of looking at email distribution. Along with this I have a project that needs to distribute press releases, and track responses. Since both projects now use the same underlying component framework (Pman.Core and Pman.Base). It seemed like an ideal time to write some generic code that can solve both issues.
He mentions the usual method of generating numerous emails and sending them to a remote SMTP server, but points out that there's a better way. You can take advantage of queuing and batch sending techniques and, the way he decided to do it for mtrack, using queue tables and a backend runner (a cron job) that uses proc_open to send out multiple emails at once. You can see the code for it here.
