the user *always must* use the one and only SMTP server responsible for his domain, especially in times of SPF, DKIM and DMARC and spoofing protections for incoming mail
And who ever said that users cannot go and use a different domain *if* using another infrastructure is what they want to do?
and how is that my problem as i am responsible for *my* servers and the domains i maintain and *nothing* else?
sent mails are on the server responsible for that different domains - so what......
they can create accounts and domains as much as they like
but i am not responsible for mails with @gmail.com, not allow my servers them as evenople as the same vice versa from gmail and domains i host
so what did you want to explain me?
that the user has a problem if he is using random sender addresses from random and don't manage to handle it over the long? who cares?
