Verify source of email issues we are facing and fixing them

Job ID: 33862207

Budget: $30 – $250 CAD

Hi, we are currently facing an issue we emails.

Emails are being sent to some of our clients asking them to click on a link. These emails were not sent by us.

Please see attached screenshot

The email in sender name @aucourantlighting.com is an email of ours, but the email @forseason.biz that is doing the sending is not from our network.

This issue has happened several times in recent weeks. I would like to find the source of the issue and resolve it.

Does it come from our dedicated server(we use plesk to manage)?

Thank you
