It's common in enterprise products where the user's first action is in a non-email.

Like I've uploaded version 1 of the plans, added some notes and the system needs to send out an email to everyone, I did the action, it's coming from me, not the system.

There's a reason it's part of the spec.

You did the action, but that does not ever justify sending the email with an envelope claiming it came from you. Because you did not send the email. It could certainly put you as a Reply-To on the email, and it might possibly justify putting your name on the From line, but actually claiming to have been sent from your email address is wrong.

Says you.

However, all the clients says "why does this email come from [e-mail], I want it to come from my email address, I'm sending it".
