Do you have an reCaptcha field in the form?

@lafunamor yes I have. You can test the form here https://www.dresslab.com/contact/
@buzztone this is the article I’ve been reading when trying to solve the problem

Same problem here, @andreu.
I’ve got a programmer debugging that shit. He says, Contact Form 7 treats everything as spam, now. We’re working on it.

Have you got to the part about trying Postman SMTP Mailer/Email Log temporarily – includes excellent email debugging.

SMTP Mail is not the issue, @buzztone
It’s Contact Form 7 where the programming mistake is.

Take reCaptcha out, @andreu, and it works again.
And it doesn’t matter at all, what you have in the “From” field.

Thank you all for your time.

The problem was in captcha as @andreas Beer reported. This is strange because I’m using recaptcha in other sites too. Does the problem appear only in the latest version of CF7?

Thanks

Never use reCaptcha as global activation on multisite. Don’t use two different reCaptacha plugins at a time.

Ok thanks. I had Really Simple CAPTCHA enabled too.
