How do I send email using a non-existent Sender?

In order to personalise emails sent by our bots (and also avoid a profusion of email accounts), I’d like to specify as Sender something like “Arnie.Bot@domain.com” where Arnie.Bot is a “spoof” address.
How can I send an email from UiPath without it verifying whether the Sender is actually a valid email account ?

unethical and impossible.
