On the contrary, this is not an argument for permitting less than 100% coverage, it's a argument for requiring greater than 100%. If you only exercise each line of code once in your tests, then you almost certainly don't have enough tests.

Your story is just a special case of not testing with enough inputs to your code. A developer wouldn't have to be familiar with this specific feature of mail servers in order to catch this in unit tests.
