Describe the bug
Unable to send an email that doesn't have an TO: address.
We were attempting to send an email that just has lots of BCCs (no TO: address) and this worked with JavaMail, but when we switched to using the Spring Cloud AWS integration it started failing. According to the documentation on SES it states:
The message must include at least one recipient email address. The recipient address can be a To: address, a CC: address, or a BCC: address.
Sample
SimpleMailMessage template = new SimpleMailMessage();
template.setFrom("Sender <[email protected]>");
template.setSubject("Subject");
template.setBody("Nothing to see here");
SimpleMailMessage message = new SimpleMailMessage(template);
message.setBcc("User 1 <[email protected]>", "User 2 <[email protected]>");
mailsender.send(message).
Workaround
To workaround this you can set the to address to be new String[]{} which is the same as passing nothing. This ends up setting the to address to not be null, but doesn't cause problems with the SES implementation.
message.setTo();
Passing null doesn't work as this creates an array with one item (of value null) which then fails because it's not a valid email.
