I'm trying to send emails with Amazon SES, but when I use default   EMAIL_BACKEND raise error:    Config:    EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' # this is   default  EMAIL_HOST = 'email-smtp...amazonaws.com'  EMAIL_PORT = 465  EMAIL_HOST_USER = '...'

  The problem is that there are two different ways of establishing a TLS  connection to an SMTP server. One is the so-called SMTPS, which is  commonly used on port 465, where the client opens a TLS tunnel right  away, and all SMTP communication happens through this tunnel.    The other option is STARTTLS, which is normally supported on ports 25  and 587. With this protocol, the client first opens a regular  plain-text SMTP session with the server, and they exchange the  STARTTLS SMTP command, after which they perform the TLS handshake, and  only then is everything transferred over a secure TLS tunnel.    Django supports both protocols, however, these days SMTPS is  considered obsolete by some people, and a lot of folks will tell you  that STARTTLS is the way to go.    You set EMAIL_USE_TLS to True in your config, this tells Django to use  the STARTTLS protocol, but you also set it to connect to a port on the  server where it expects the SMTPS protocol instead. If you want to use  SMTPS (which is what you need to do in order to connect to port 465  successfully), you need to set EMAIL_USE_TLS to False, and instead set  EMAIL_USE_SSL to True.    The other option is, as Raffaele suggested in another reply, to keep  using EMAIL_USE_TLS, and switch the port to 587.    Good luck,    Michal
