mail() and To: headers

[Geoff Soper]

I'm using the mail() function to send e-mails. The first argument to the
function is the e-mail address the mail will be sent to. I understand this
should just be in the format 'address@domain ' and not '"Name"
<address@domain >' and that if I want to specify the name of the recipient as
well as the address of the recipient I should pass it as an addition header.
This works fine locally under Windows and Apache but remotely under Linux
and Apache the resultant raw message has 2 To: headers meaning the client
displays it as being sent to 2 addresses (the same address twice). Am I
doing this correctly? It seems a clumsy way of doing it, especially as
SpamAssassin marks down a message with only an email address in the two
header.

Thanks,
Geoff

I've been using it with the first format without problems.

Basically, yes. The documentation's examples *imply* that the first
parameter should be a comma-and-space-separated list of one or more
addr-specs, but I can't find where this is explicitly stated.

To send mail to a single mailbox, probably.

Again, that's probably correct; the docs are waffly.

OK. But read the Manual's note, which feigns a quotation:

| The to parameter should not be an address in the form of "Something
| <someone@exampl e.com>". The mail command may not parse this properly
| while talking with the MTA (Particularly under Windows).

"PHP: mail - Manual",

http://www.php.net/manual/en/function.mail.php

And there are related user-comments dated 2003-01-17 and 2003-06-09:

http://www.php.net/manual/en/function.mail.php#28610

http://www.php.net/manual/en/function.mail.php#32848

We're left wondering what the Manual's preferred forms are. Had it
referenced RFC2822, and stated that the first parameter to mail should
be a comma-[and-space-]separated list of addr-specs, our questions
would be answered. As it is, we have to guess.

Reading this excerpt from the manual again, is it the case that any mail
server the message might pass through potentially might have a problem or is
it just the SMTP server my script talks to directly? If it's the latter then
it works so it must be OK for me to use but if it's the former then it's
about taking a chance.

Any suggestion?

Thanks,
Geoff

Just the SMTP server your script talks to directly.

Conversations between user-agents and MTAs are private matters. What
happens after that, however, is covered in RFC2821.
