Envelope sender is bounces+...

Hello,

 

we get a lot of advertising email and also regular info-email where the sender typically is 'bounces+xxxxx-firstname-lastname=domain.com@somedomain.com. The sender address '..firstname.lastname..' is a legit person in our organization. For the sake of the case let's call our employee Bill Johnson and our company is Contoso. So Bill.Johnson@contoso.com at our company get email where the envelope sender is stated to be bounces+5291031-0a54-bill.johnson=contoso.com@email.somedomain.com

 

SENDER:bounces+5291031-5c0e-bill.johnson=contoso.com@email.somedomain.com
RECIPIENT:

bill.johnson@contoso.com

 

Why is that? We had some spam to our organization, so for a while I blocked all email where the envelope sender contained 'bounce+..'. However that was a bad idea, as we get a lot of legit email with bounces'.... as part of the envelope sender domain.

Can someone please help me clearify the reason why the sender address being bounces+?
