Netmail, e-mail, and local mail are all treated the same when it comes logging
and reading.

If the user has unread personal mail (of any kind), they're prompted if they
want read their mail upon logon. The logic is in logon.cpp (`mailw` is total
mail waiting and `mailr` is the amount of already read mail waiting):
```
if (text[ReadYourMailNowQ][0] && mailw) {
	if ((mailw == mailr && !noyes(text[ReadYourMailNowQ]))
	    || (mailw != mailr && yesno(text[ReadYourMailNowQ]))) {
		uint32_t user_mail = useron.mail & ~MAIL_LM_MODE;
		int      result = readmail(useron.number, MAIL_YOUR, useron.mail &
MAIL_LM_MODE);
		user_mail |= result & MAIL_LM_MODE;
		if (user_mail != useron.mail)
			putusermail(&cfg, useron.number, useron.mail = user_mail);
	}
}
```

There are no pointers for mail, but each message its own on "read" flag, so we
do know when (and how many) unread mail messages are waiting for the user.

I'm not sure what you mean by "parrot back to the BBS".
