I'm using Openemm 2013. It's hosted on an EC2 instance, sendmail routing mail through SES. The problem is that Openemm doesn't send all the emails that it should. First I laucnhed a batch to ~10k recipients (Openemm mailing shows that). SES reported only 4k emails. Checking Sendmail logs, found that indeed only 4k emails were sent. Next there were 2 batches of 3500 and 5500. Only 7.5k made it to SES. Sendmail queue is empty and I didn't mess with it.
So, the question is - where do I look for the lost ones? Or am I missing something?
