使用Swiftmailer在Heroku中发送电子邮件的问题

Question

I wrote an application in symfony 4. I deployed it on the heroku. Everything works as it should with the exception of sending emails. When I trying to send an e-mail from the console like this:

heroku run php bin/console swiftmailer:email:Send

Exception occurred while flushing email queue: Failed to authenticate on SMTP server with username "healthcard95@gmail.com" using 1 possible authenticat ors. Authenticator LOGIN returned Swift_TransportException: Expected response code 235 Please log in via your web browser and then try again.

This is my swiftmailer.yaml file:

swiftmailer: transport: gmail username: username password: ******** host: localhost port: 465 encryption: ssl auth-mode: login spool: { type: 'memory' } stream_options: ssl: allow_self_signed: true verify_peer: false verify_peer_name: false

How to fix this error?

Answer 1

The problem is in Gmail. Although I have set up security to allow less secure applications and e-mails from local hosts are sent correctly when I perform the same operation in gmail heroku, I see a new device - unfortunately I can't add it to trusted devices, therefore it's blocked.

The solution was to change mail, eg on yandex.com. Here is an example file swiftmailer.yaml correctly configured for heroku:

 swiftmailer: transport: smtp username: username password: ******** host: smtp.yandex.com port: 465 encryption: ssl auth-mode: login spool: { type: 'memory' } stream_options: ssl: allow_self_signed: true verify_peer: false verify_peer_name: false
