Let's begin with the illustration of the problem with undeliverable responses:
Imagine a situation you are expecting a very important package. The question is: do you release your dogs to prohibit the postman to deliver the parcel? We believe not - you will keep your dogs leashed. The question is, why people don't do the same in case e-mails. Using other words: if you think the e-mail from us is important, please leash your dogs (e.g. anti-spam filters) to allow the postman to deliver it.
Cases where our postman complains about "unleashed dogs" / other problem with delivering our response:
