Agreed the real problem is getting other servers to accept your mails.
While I can understand the paranoia, bottom line is that the number of domains that can successfully send mails is now seriously limited to a few big players who now have a virtual monopoly on emails.
Which is not really good in my opinion...
It's interesting because in French, to speak literally translated would give something like "take the talk". (prendre la parole)
So when somebody speaks, he takes something with, I guess, the hidden assumption that he/she's preventing others from taking it.
