The prices that SurgeMail 6.5a-1 estimates for me seem very high. (I currently have 500+ GB of mail, and it's estimating a $270 monthly Amazon bill.)

Are those values based on the earlier DevPay system?

Even recalculating for regular S3 pricing, this is not a cheap feature to implement as mailbox volumes continue to grow.

Have you considered supporting Amazon Glacier as an alternative?

Best,
Chris
