IMO, the mail() "to" parameter should represent mail envelope RCPT-TO
value, not the mail "To" header. And should never be substituted into
header "To:" field if it not defined by user.
Else it defeats the use of mail() function, when you are writing, i.e.,
a mailing list handler.

Description:
------------
The docs for the mail() function state the first parameter ($to) as
being obligatory. They also state that "the formatting of this string
must comply with ยป RFC 2822".
This would lead me to expect that passing a string not containing a
valid address would cause a warning or at least a notice. This isn't
so.
While technically I'm fairly sure this is correct behaviour (AFAICT RFC
2822 states that either To, Cc or Bcc should be included, so leaving
*out* To shouldn't be a problem and in fact isn't, and non-email
addresses are also supported) the docs suggest that under PHP it is in
fact illegal.
I would expect that passing NULL or an empty string would result in the
entire To: field being omitted in the headers (it's now in fact empty,
which doesn't seem to conform to RFC 2822 which says that if you *do*
include any such header it should contain a comma-separated list of at
*least* 1 address). Whether or not a notice should follow something that
doesn't appear to be an emailaddress is a matter for debate - I'd
personally leave regexing to the users of the function, but then the
manual isn't correct.
So, actually it's something of a bug/feature in the mail() function as
well I believe, and passing NULL as the first parameter should cause the
To-header to be omitted.
But since including a To-header seems like good form mostly the docs
are, I feel, somewhat incomplete in this respect.
Reproduce code:
---------------
<?php
mail(
NULL,
'test',
NULL,
<<<EOT
Bcc: [email protected]
test
EOT
);
Expected result:
----------------
Depending on how you feel about $to being obligatory, either a
better-formed email being sent, or a notice or even warning thrown by
PHP.
Actual result:
--------------
[...snip...]
To: <-- violates RFC 2822
Subject: test
test
