Summary0018276: Improve send rate when using AMAZON SES
DescriptionI was helping someone try to improve the throughput when using AMAZON SES, and switched from sending through the SES SMTP server to using the API over http.

There was an improvement in the send rate but not really significant. SMTP was about 2000/hour, using the API went up to about 3,500-4,000/hour.

I found a stackoverflow topic that recommended reusing the curl handle and setting keep alive headers

http://stackoverflow.com/a/9219352 [^]

These changes had a much bigger effect, increasing the send rate to 7,000-8,000/hour.

I will create a pull request that has the very small changes.
