Bug or misconfig in email

Hi!
Today, I received a complaint from a customer regarding receiving a lot of spam emails. After investigating, I found that the emails were being sent from [email protected], an account that does not exist. I am unsure if there is any relation to the admin hestia account, but it definitely does not have an email account. SPF, DKIM and DMARC records are ok.

Mail are send over php mail function …

Hi Eris!
thanks for quick response.

Why are those emails not being blocked by the anti-spam filter even though they are sent over the PHP mail function?

Outgoing mail never check by the span filter at te moment:

Website of user admin is sending too many emails - rate overlimit = 200.0 / 1h

Check what website is active on this user and disable it and see what happens.
