php mail() function

I'm trying to use the php mail() function to send a mail within a php
script. This is using PHP 5.2.4 and Ubuntu Hardy Heron linux. The
script runs fine and the return value of the mail function is TRUE,
but the mail is never received. I'm trying to send an email to my
gmail account via the local server on my machine, just to test if this
script works.

I installed postfix because I read in several places that people have
had good luck with that mail program. From what I can tell, postfix is
working. I can do:

telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 homemade ESMTP Postfix (Ubuntu)
ehlo localhost
250-homemade
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

After the php script runs, I type 'mailq' and get the result 'mail
queue is empty.' If I check /var/log/mail.log, this is what I see:

Re: php mail() function

The problem is you won't be trusted to deliver mail directly to most
mail servers unless you have a static IP. Even then thats no
guarantee. What you have to do is relay through your ISP's SMTP
server where you're "trusted". You should also be able to setup PHP
to use your ISP's SMTP server and never touch the SMTP service on your
local machine (if you don't feel like playing with Postfix).

Re: php mail() function

How would I determine my ISP's SMPT server ID? And do I need to edit
main.cf in order to use that server?

Also, is there a way to test the script just sending an email locally?
I tried sending the email to userid@localhost, but the email was still
not received.

What ID? There's no ID needed. You just configure postfix to relay any
non-local mail sent to it to the SMTP server at your ISP. Check the
headers in incoming mail sent to you for the name of that server. It's
likely the same for both incoming and outgoing mail. Something like
mail.myisp.com.

One other note. People look at me like I'm crazy when I mention this,
but I've seen it quite a bit at various internet mail servers.
Sometimes, in order to accept email from you, the internet mail server
must see you *receive* mail within a certain time period prior. That is,
you have to go fetch your mail at the ISP, which opens a "window" into
the SMTP server for a limited time. Then you can tender mail to the
internet mail server. I don't know that your internet mail server
operates this way, but it's something to consider. I've had to deal with
this before myself.

Configuring local SMTP servers, like postfix. Check and see if Ubuntu
has some sort of setup utility for this. Or try

dpkg-reconfigure postfix

Setting up mail servers is tedious and error prone, unless you've done
it a lot. Read The Fine Manual on postfix.

It will work, assuming three things:

1. You have an actual user set up on the system to receive mail. That
is, an actual user on the system, with an entry in the passwd file and a
home directory, etc.

2. Postfix is configured to deliver truly local mail to local addresses.
More postfix configuration fun.

3. Postfix is actually running and properly configured. If not
configured properly, it may refuse to run.

In any case, linuxmanmikec's comment about the internet mail server not
trusting you on a dynamic IP is spot on. The web of email trust is such
that internet mail servers only trust other internet mail servers. And
*your* internet mail server will trust *you*. So to get mail to that
other internet mail server over there, you'll have to give it to *your*
internet mail server, which is the only one that internet mail server
over there will trust. The "bounce" message you got indicates that
relaying from you is forbidden at the destination mail server.

This is commonly known as POP lock and is one of the two main ways that
a mail server allows you to relay a message. If you have authenticated
via POP3 (i.e. checked your mail) in a certain period of time then the
SMTP server will let you send. The other main one is by authentication
(username/password) with the SMTP server when you attempt to send mail.

This is fairly accurate in premise but just to clarify. Mailservers
don't operate like this by default and there is really no "trust".
There are public blacklists that a mailserver can be configured to use
that tell the mailserver not to accept mail from servers on the
blacklist. The blacklists may contain servers that allow anyone to
relay email, compromised servers, servers known for spam, ip ranges
known to be held by spammers and *ranges that ISPs designate as dynamic
or used for subscribers (DSL, cable, dial-up customers, etc. because
they shouldn't be relaying email).

Regarding the rejection of dynamic IPs by smarthosts, are you saying
that it's a "blacklist" of sorts that lets them know an IP is dynamic?
(Serious question. I don't know the mechanism by which they determine
what is and isn't a dynamic IP.)

Re: php mail() function

i faced the same problem quite a few times.

the general email route is
php script -> sender smtp server -> receiving mail server
in your case path 2 is broken. meaning port 25 is blocked by your ISP

the work around is:
1. see if your ISP provides you with an SMTP account that is not blocked (OR)
2. try using a socks

I run my own mail server and use the zen blocklist from spamhaus.org.
The zen list combines all the the anti spam lists plus all IPs
designated to end users (http://www.spamhaus.org/zen/)

The reason for blocking end users is that a lot of SPAM is sent out by
compromised machines from some home Internet connection. I am currently
getting about 5 connections every 2 seconds from compromised computers
attempting to spam my server. The origin is usually a dynamically
assigned IP from Sprint or Comcast (USA ISPs).
So blocking the end users from sending SPAM tends to cut down on a LOT
of junk.

Here is a bit more info about the end user blocklist.

You are talking about two different mechanisms here. The black or grey
lists are services that track known open relays and other sources of
spam, viruses and assorted malware. Anyone can subscribe to them and use
them to validate relay requests.

There are also services that keep track of valid domain addresses and
the IP assigned to them. They are usually called DNS hosts. These can be
polled to identify the IP address for authorized domains and hosts.
There are even special records for the email severs within a domain.
Most dynamically allocated IP addresses will not show up on these
servers unless you have access to a service authorized to inject
records.

So basically, qmail did a DNS lookup on your host/domain name and did
not find a record pointing to your server. Therefore it rejected your
request.

You will have to ask your ISP for the address of their SMTP and POP
servers if you don't know them. But usually your email client is already
configured to talk to them. I would just go into my Thunderbird setup
and look up those addresses.

I found the mail server for my ISP (shawmail.vc.shawcable.net) and

I still don't receive the mail from the PHP script though. The error

Re: php mail() function

i never worked with postfix, but form my experience with hmail server
i can say that you need to relay through a mail account of ISP(not the
server itself)

1. Not sure why you have square brackets around the relayhost value.

2. You're getting a bounce from the ISP's mail server, one indicating it
still won't allow relay.

3. I suspect the relayhost name is wrong. This may be the name you find
in the mail headers on messages relayed to you, but I doubt it's the one
you should use to post to. I could be wrong, though.

4. All due respect to Kranthi, but I believe he's wrong about relaying
mail from your webserver to the ISP's mailserver. I believe the ISP's
mailserver doesn't care, as long as the mail comes from your "pipe". You
could probably call yourself "pizza@pepperoni.com" and your ISP would
accept it. It's just the From:. Again, I could be wrong.

5. This would be a lot simpler if you just call Shaw and ask them for
the name of the mailserver, and ask them if it's a problem for you to
post mail from your internal webserver to their mailserver. Then ask
them why such posts might bounce with a 5XX error.

All the ISPs I have used so far require the user to authenticate even
when on the same network.
So if you want to relay through the SMTP server of your ISP you need to
login first. I think that is what Kranthi said

Try this:
1) Set up a password maps file (/etc/postfix/sasl_passwd) with the content:
mail.ispserver.com username:password

Now Execute these commands
# chown root:root /etc/postfix/sasl_passwd
# chmod 600 /etc/postfix/sasl_passwd
# postmap /etc/postfix/sasl_passwd

And change your config to this /etc/postfix/main.cf:
relayhost = mail.ispserver.com
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous

Now reload postfix and try it again.
# postfix reload

Re: php mail() function

Thanks, John. I set up the sasl_passwd file as per your instructions
but am still getting status=bounced. I'm wondering, what should the
values in main.cf be for 'myhostname' and 'mydestination'?

These pages give some info on the Shaw mail servers, but I'm not
certain which I should be using:

http://www.shaw.ca/en-ca/CustomerCare/InternetSupport/Reside ntial/Email/ServiceDetails.htm

http://www.shaw.ca/en-ca/CustomerCare/InternetSupport/Reside ntial/RoutersandShawServerNames.htm

Also, I notice that in the mail.log file, the 'from:' value is
'www-data@homemade'. The actual 'from:' value is provided to the php
mail() function via a web form, so should be somebody's email address
(e.g. my own in this case).

I think PHP will use the apache user and domain to generate the email
address. I use my own smtp function so I can't say for certain.

One thing you could try is to use a valid email account on the server
for the FROM address so that you can receive the bounced message. The
actual message should contain more information.
Alternatively attempt to increase the loglevel of postfix so you get
exact feedback of why the connection is failing.

As far as which server to use. I think this page lists the correct one:

It sends the bounced message to /var/mail/www-data and I get this:

I will investigate how to change the loglevel of postfix, because
right now the error messages don't seem very helpful (at least to me).

Although 5.0.0 actually means something else I'm pretty sure you are
rejected because of an invalid sender address or domain. Use a sender
address that is valid with your ISP's mail relay.

Re: php mail() function

I also suspect that the problem is due to the sender address, but I
have tried using the shaw email address for the From: address that's
given to the mail() function and it still gets bounced. It seems like
the ISP should consider that address valid.

Re: php mail() function

But it seems like the 'From:' address being given to the PHP mail()
function is maybe being ignored, because the error log lists
'www-data@homemade' as being the sender, rather than listing the shaw
address.

The snippet from the PHP code:

$email =3D $_POST['email'];
....
mail($to, $subject, $msg, 'From:' . $email);

I have tried setting both $to and $email to be the same shaw address
since I assumed it should be recognized by the mail server, but it's
still getting bounced. So why is 'www-data@homemade' being listed as
the sender? Any ideas?

I strongly recommend you call the help desk at Shaw and ask them to
explain what is happening. They should know what is going on with their
servers. Everyone on this list appears to be guessing at the problem,
which is not likely to help you.

But they are educated guesses :)

No seriously, without a definitive error message it is hard to say for sure.
Since he only needs postfix on the server to allow php to email out I
may have a different solution for him.
I sent him my custom smtp_email function which talks to the ISPs SMTP
server directly and supports authentication.
Lets see if that help.

Re: php mail() function

After a long delay, I've finally got mail working. I had decided to
move on in the book that I'm working through (Head First PHP & MySQL)
but doubled back to address the mail issue again. This is how I
finally got it to work:

1. Switched to XAMPP for linux rather than using my existing versions
of mysql, php and apache.

2. Uninstalled Postfix and reinstalled Sendmail. Then I followed the
instructions here:

http://dbaron.org/linux/sendmail

I can't vouch that the method described at that link is completely
safe and secure, but it worked for me and was very easy. I've spent
many hours and days trying to get this to work so am very relieved.

My only complaint is that there is quite a long delay after submitting
report.html (from Ch. 1) while it says 'waiting for localhost...'. It
can take up to 20 seconds or so before sending and giving
confirmation.

Thanks for all your help.

Re: php mail() function

It looks like using XAMPP wasn't strictly necessary. I tried running
this example again using my previous versions of mysql and apache and
it worked fine. So the key is to configure Sendmail as described at
the URL I gave.
