If I try to use Boto 3 to send an email with SES with a Reply-To
header that doesn't match some other header in the email, using a script like this...
import boto3
client = boto3.client('ses')
client.send_email(
Destination={
'ToAddresses': [
"someone@example.com"
],
'ReplyToAddresses': [
"someoneelse@example.com"
]
},
Message={
'Body': {
'Text': {
'Charset': "UTF-8",
'Data': 'Bla bla bla',
},
},
'Subject': {
'Charset': "UTF-8",
'Data': 'Bla bla bla',
},
},
Source="My Company <noreply@example.com>",
)
... then I receive an error like this:
Traceback (most recent call last):
File "/Users/markamery/test.py", line 24, in <module>

botocore.exceptions.ParamValidationError: Parameter validation failed:
Unknown parameter in Destination: "ReplyToAddresses", must be one of: ToAddresses, CcAddresses, BccAddresses
This doesn't make much sense to me. What I'm trying to do here seems to be a best practice (see https://stackoverflow.com/a/14555043/1709587) and according to https://forums.aws.amazon.com/thread.jspa?threadID=60093&tstart=0, as of 2011, you can use "any email address" in the "Reply-To" header.
What causes this error? Have SES's rules been changed again since that forum post from 2011? Is the error I see above an undocumented restriction for accounts that are in the sandbox, like mine? Or is this a bug - is Boto 3, on the client side, applying stricter validation of ReplyToAddresses
than the AWS API itself does?

According to the boto3 docs you need to put the list of reply-to adresses in an argument outside of the Destinations argument. It seems strange to me too.
send_mail(
...,
Destination={...},
ReplyToAddresses=[
'someoneelse@example.com',
])
