I have set up SES and DKIM and I sent a few emails via a PHP script to myself. The last time I ran the script I got the following error:
Email not sent. SMTP Error: data not accepted.SMTP server error: DATA END command failed Detail: Throttling failure: Maximum sending rate exceeded. SMTP code: 454
I have only been sending emails to myself and I need to be able to do this quite a lot in order to develop my website.
Edit: I went to Amazon SES > Account dashboard and under 'Daily email usage' I can see have sent 21,428 emails. I am worried about this as I have only knowingly sent about 5 emails. Either an error has occurred (possibly me programming) or perhaps someone has accessed my account. I would really appreciate some help sorting this out as it is a bit worrying.
