    Issue Email Spoofing subsequent subsequent plesk.domain.com deceptive site ahead

    I have Wordfence installed on all of the sites, and check them regularly. In any case I checked the files/folders and since I've had several malware clean-ups done so far(not on these sites), I can confirm that they are clean. Only thing that could possibly mess things up is that couple of the...

I have the standard WordPress vulnerabilities(WordPress <= 6.2 - Unauth. Blind SSRF vulnerability/WordPress tagDiv...

    I want to thank you all for the support so far. This is a summary what I've done and everything seems to function properly for now at least, except for the BIND issue...

    Resolved no SASL authentication mechanisms

    I am using the free mail extension. I suspect maybe the issue was caused by the issuing of the wilcdcard certificate for the no host domain using the digitalocean tutorial, which worked, but maybe caused all this. Should I reinstall postfix and dovecot to revert the change? Any assistance...

    The snippet you provided was the default configuration, yes. I provided the initial configuration in my first post. However, I was constantly getting the error, whatever I tried to fix the issue.

    I would like to add to this, as it might be useful for someone.
