Your problem
My problem is:
I configured Mautic to send emails through Amazon SES API and test emails are working OK, but for every email sent Mautic logs the following message:
These errors are showing in the log:
mautic.ERROR: SES API Error: Illegal address
Steps I have tried to fix the problem:
I reverted to sending via SMTP (through SES) and all seems OK, no log messages at all. Is the above error message something to be worried about? I googled it, but without success.
