Hi,
I’m having an issue with email. I configured SMTP parameters in Parameters.php, but mails aren’t sent.
I checked queues with docker-compose exec rabbitmq rabbitmqctl list_queues name messages messages_ready state, everything seems fine (messages in mail queue listed and ready).
I also checked docker-compose logs, and I haven’t seen even a hint of an error.
Any idea about that ? 
Thanks ! 
Philippe
Hello,
to check the errors try this procedure:
sudo docker-compose exec php php bin/console twake:mails_queue (will run for 1 minute)(retry adding secondary mail multiple time to fill up the queue to be sure to intercept the error as if an error occur on a mail task it is delayed for 1 minute and there is an other consumer running in background)
Hi,
Thanks ! I tried it, got this error :
Fatal error: Uncaught Swift_SwiftException: Unable to load DKIM Private Key [error:0607A082:digital envelope routines:EVP_CIPHER_CTX_ set_key_length:invalid key length] in /twake-core/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Signers/DKIMSigner.php on line 675

I didn’t have configured dkim, and thought the block in Parameters.php could be left empty. Then I commented it, executed docker-compose restart, and retried, but the issue still occurs
Here is the complete stacktrace :

Do you want that I push an issue on github ?
Philippe
Yes an issue on github would be appropriate, it’s on me this time we did not implemented the case where DKIM is not defined!
Alright, I will push it then
Thanks for your time, sincerly ! 
Philippe
