Management Center failed to send emails due to authentication errors

[Ola Adel]

Dears,

 

I've an issue with management center appliance ( v2.2.1.1), as i cannot send emails when a job finished it's task, in the time SMTP configuration (Mail Settings) is as follow:

- Mail Server: Mail Server IP

- Mail Server Port: 587 (Custom Port)

- From Address: [e-mail]

 

Notes:

- This SMTP Server with customer port (587) uses a secure connection.

- On mail server a policy is created with MC IP address not to require authentication from that IP.

- We imported exchage server certificate on management center.

- When we use default port 25 (not secure port) it works well.

- When checking MC logs we found the following error 

caused by: org.springframework.mail.MailAuthenticationException: Authentication failed; nested exception is javax.mail.AuthenticationFailedException: 535 5.7.3 Authentication unsuccessful

Hi Ola,

I would advise taking a packet capture from Management Center's view and generating an MC diagnostics capture.
