In Mac Mail, user can choose different SMTP servers. So if they have multiple accounts, let's say, one email [email protected], [email protected], [email protected], they can choose (accidentally, most of the cases) the SMTP server of [email protected] for sending out [email protected] and [email protected].
By sending that way, some servers seeing it as forged email addresses, and can block the emails. Is there any setting in Exim to prevent that happens?
Any idea? Thanks.
