How to debug the rails mailer

Question

I am using mandril mailer, I have set up my mailers and everything was working fine, at some point the mailer stopped working, I am trying to send a message from the rails console

TaskCompletedMailer.client_created(email: 'mymail@gmail.com').deliver

I am getting a message in the console that the email has been delivered.

[{"email"=>"mymail@gmail.com", "status"=>"sent", "_id"=>"184e03d40a874fa892b5549173ccba80", "reject_reason"=>nil}]

but the mail is not been delivered into my account. How can I debug that ?

Answer 1

Check in the logs what can you see there. Probalby the action_mailer config is not correct for your current enviroment.

Answer 2

您可以尝试使用协议分析器（例如Wireshark）来监视网卡上的SMTP通信，并检查rails应用发送给它的真实程度。
