Our email server used by others for spamming

I am using open source mail server which is iRedMail. We follow the standard procedure how to set it up given by iRedMail too. Then we try also to follow standard procedure given by google and MX Lookup Tool for having a mail server. But this past few weeks we encountered that our mail server is used by others for malicious matter like spamming. We tried to change all of credentials but still, the spamming is continuous. I attached the screenshot so you can have idea.

You can't attach screenshots here… You're going to have to provide more information…

  1. Are the spammers able to login to your server using fake accounts?
  2. Are the spammers able to use your server as an open relay?
