comment Configure sendmail to reject emails without from addresses
Hence I asked if it's safe. Instead of spamming the question with comments like "oh, a bad idea, oh you request to do bla bla bla" make some effort and say why. This is why people use this site and ask questions. To learn something, isn't?

comment Configure sendmail to reject emails without from addresses
Why would a bounced message have the 'from' address set to '<>'? Even if the sender mistyped the recipient's address, they would be bounced by a legitimate server and should have the 'from' set to 'postmaster' or other legitimate email address?

They are not bounces. Those are incoming emails that are being rejected anyway with SMTP error code 550 User unknown as they usually are addressed to a random user name.
