[Yan Prada]

I set up my jira on aws server. 
I want to send email using jira but I got an error.

An error has occurred with sending the test email:
com.atlassian.mail.MailException: com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first. s2-v6sm45691890pfk.133 - gsmtp

Hi @Yan Prada

Port 587 is a secure port and your selected protocol is non secure

Please try with port 25 or change the protocol to SECURE_SMTP

Regards

Dave
