I know in the "old days" it was good practice to shut this off.

But nowadays I have heard that it improves deliverability of email. In the old days people were not worried about spam (or having their outbound email rejected), so that made sense.

Of course, the question is only relevant to servers that send email.

What is the current, common practice among discerning Linux admins? Run identd or leave it off?

Thanks
