Following at the letter the amazon SES tutorial:
http://docs.aws.amazon.com/ses/latest/DeveloperGuide/postfix.html
but auth is not working and giving errors like
No worthy mechs found
SASL authentication failed; cannot authenticate to server
and so on?
Make sure you have the proper auth libs installed
yum install cyrus-sasl cyrus-sasl-plain cyrus-sasl-md5 |
