[Feature request] Option to reject/warn of bare line feeds

[ahmedtrabelsi-eaton]

Hi all First of all, thank you to the developers for this great mail testing tool, which saves us a lot of time to set up a big mail server. Then, I looked in the doc but without success: did you check the formatting of the content of the email, especially if it complies with the CRLF (Bare line Feed) standard? In which case, is there an option to add to our conf to reject these emails? Well, if not, I'm keen to develop it;)

At the moment, no there is no such feature.

I would be open to a PR on this with the default being permissive as it is currently (and perhaps generate a warning for the message).
