I am not sure what "multiple from addresses" actually means. It is not
possible for an email to come from more than one email address at a time
in reality.
Of course, as you already know, the sending e-mail system can put

Multiple addresses in one From: header are allow
Thanks a lot Ron,
I probably didn't explain myself well.
The contact form was fixed before posting this topic here, but I'm
currently managing a personal server where I host family websites
among many other services and also a Postfix setup where I handle
about 8 different domains. As you said, I
You need to fix your contact form.
There is no such thing as multiple from addresses.
As Tom said, your contact form is not creating an email. It is
collecting information that it processes to produce some intelligent
response or that it
sends to you (or an automated proxy) requesting that you (

Thanks a lot for you comments, opinion and help! :)
As Tom said, before posting this question here, I already noticed the

Hi Viktor,
thanks a lot for your opinion.
Could you explain to me which would be the benefits of implementing
such behaviour on a filter or milter instead of doing it on
header_checks?
Also, do you know in which cases would be useful to allow or make use
of multiple From addresses? Just in case

If you're seeing multiple addresses in a single From: header you may
be able to carefully craft a header_checks to detect them, but
