I perfectly understand why a contact form would reject a mail with the domain "example.com". This is obviously not a valid email domain (and may be the default domain used as greyed example in the contact form).

The contact form is linked in the article [1], and it rejects genuinely valid emails. You can try it yourself and see it doesn't have greyed examples, and that the problem is not example.com but the use of symbols. For example, greffe_acces@montréal.ca is a valid in-use email [2] that is rejected.

example.com was only used to take an example screenshot.

[e-mail] is a perfectly cromulent email address.

That's explicitly a fake email address, as it's a special-use domain name reserved by IANA to be used as example/placeholder.
