Did you remember to activate it AND push the save button on your profile page ?

If your problem persists even after uninstalling my plugin, it’s obviously not caused by my plugin.

That’s probably the reason, Wordfence also has a hook into the authentication process.

Do you have other security plugins enabled ?
Could you perhaps email me a list of your currently installed/active plugins ?

After activating the plugin on your user profile page, did you remember to push the save button at the bottom of the screen ?

Another tip:

Handling DMARC reports manually is time consuming and painfully complicated.
I’ve been using dmarcian.com to handle my DMARC reports for years now, I’m really happy with the features available.

Sending an email to checkmyauth at auth.returnpath.net can be used to test authentication

For email to be DMARC SPF aligned there must be a relation between the senderenvelope domain (some call it returnpath or bounceaddress) and your From: domain (that’s the visible from address)

Your senderenvelope domain is 116-prod.mail-out.ovh.net
that is not in any way related to marsinval.fr

I don’t know if ovh.com will let you modify then senderenvelope domain, if not here is another solution, use mailgun.com for outgoing email.
There is a WordPress plugin for interfacing with mailgun.

By the way mail-test.com isn’t really a great tools when it comes to testing authentication, they have completely misunderstood how SPF works. Read more here : https://space.dmarcian.com/a-common-misconception-about-spf/

Looking at the mail-test.com report.
Your email passes DMARC, but only because you DKIM sign it.
It isn’t DMARC SPF aligned.

You have pct=20 in your DMARC record, that’s the reason, your DMARC policy is only being applied to 20% of your email, the rest gets “sampled-out”
Since you have a p=none, there is actually no need for the pct parameter, set it to 100 or remove et entirely.

Perhaps DNS TTL is playing games with you.

Your configuration appears to be fine : https://www.dmarcian.com/dmarc-inspector/marsinval.fr

Or perhaps you forgot to save your user profile after setting everything up ?

My guess is you enabled it on another account, not the one you’re logging in with.

Hm no not really, but you could try to disable ALL login related features in iSecurity

Yes thank you for the email.
Reason it doesn’t work is that iSeciruty plugin overrules my plugin.

I can’t do anything about that

Best regards
