I’m using phpList to send emails through Amazon Simple Email Service (SES) via smtp.
At the moment I am dealing with a couple of mailing lists with between 500-1000 subscribers each and I only need to send emails to them once a month. SES has given me a much larger allowance and they charge pay-as-you-go and I’m a bit concerned about what could happen if there was some method whereby the subscription page is spammed and I get a bill for all of the confirmation emails that get sent out.
If I set MAILQUEUE_THROTTLE = 10, will this limit the whole system to 1 message every 10s or just the campaign sending?
Are there any other features to protect against this sort of thing or should I be dealing with it elsewhere / not worrying about it?
