I’m trying to get kobo’s automated email function to work with AWS SMTP settings. When I build kobo I enter the settings and after they appear in the smtp.txt file
EMAIL_BACKEND=django.core.mail.backends.smtp.EmailBackend
EMAIL_HOST=email-smtp.eu-west-1.amazonaws.com
EMAIL_PORT=465
EMAIL_HOST_USER=user@mydomain.com
EMAIL_HOST_PASSWORD=USER-PASSWORD
EMAIL_USE_TLS=True
DEFAULT_FROM_EMAIL=user@mydomain.com
This doesn’t work and I get a 500 error when trying to register as a new user. However when I enter settings for a Zoho account I have everything works as expected.
So I test the AWS SMTP settings using swaks. When I use tls I get
swaks --to me@gmail.com -f user@mydomain.com -s smtp.mail.eu-west-1.awsapps.com --port 465 -tls -a LOGIN
Username: user@mydomain.com
Password: USER-PASSWORD
=== Trying smtp.mail.eu-west-1.awsapps.com:465...
=== Connected to smtp.mail.eu-west-1.awsapps.com.
<** Timeout (30 secs) waiting for server response
-> QUIT
<** Timeout (30 secs) waiting for server response
=== Connection closed with remote host.
However when I use tls-on-connect (-tlsc) it works as expected, I receive an email to my gmail account, which shows that the AWS SMTP settings work.
swaks --to me@gmail.com -f user@mydomain.com -s smtp.mail.eu-west-1.awsapps.com --port 465 -tlsc -a LOGIN
Username: user@mydomain.com
Password: USER-PASSWORD
=== Trying smtp.mail.eu-west-1.awsapps.com:465...

Is there some issue with django.core.mail.backends.smtp.EmailBackend and AWS SMTP?
Does anyone have AWS SMTP working in kobo?
