sendmail - php mail() function

Hi everybody,

I have a problem with sendmail not sending emails while I am using php mail() function.

My setup is a local LAMP server on Ubuntu, I am using it(or better-setting it up at the moment) as my test web server.

What I have noticed is when I login to the server via STH and run:

czeslawoo@sthserver:~$ sendmail realemail@google.com < testmessage

my email is dispatched and i can recaive it in googlemail.

syslog looks like this:

Feb 16 00:50:22 sthserver sendmail[22458]: My unqualified host name (sthserver) unknown; sleeping for retry
Feb 16 00:51:22 sthserver sendmail[22458]: unable to qualify my own domain name (sthserver) -- using short name
Feb 16 00:51:22 sthserver sendmail[22458]: p1G0pMYt022458: from=czeslawoo, size=23, class=0, nrcpts=1, msgid=<201102160051.p1G0pMYt022458@sthserver>, relay=czeslawoo@localhost

but when I am running my php scrip I have something like this:

Feb 16 00:59:59 sthserver sendmail[22475]: unable to qualify my own domain name (sthserver) -- using short name
Feb 16 00:59:59 sthserver sendmail[22475]: p1G0xxxI022475: from=www-data, size=134, class=0, nrcpts=0, msgid=<201102160059.p1G0xxxI022475@sthserver>, relay=www-data@localhost
Feb 16 01:00:01 sthserver sm-msp-queue[22496]: My unqualified host name (sthserver) unknown; sleeping for retry


What Ive noticed is :
nrcpts = 0 - it cant be good:/
user used in a second case is www-data, and that = apache as far as i know.

Is this just a user related problem?? www-data user does not have rights to use sendmail?? How to make this work??

I dont realy understand sendmail and sorry if this is a trivial problem but I spent so much time on setting this server to work lately ... that i need to now how to fix this problem first and then I look at it and learn how ...

sendmail version is 8.14.3

let me know if you will need any more info

tyvm for help

ps:
php script receive data from simple html feedback form and looks like this:
--------------------------------------------------------------
error_reporting(E_ALL);
ini_set('display_errors', '1');

$email_from = $_POST["email"] ;
$message_from = $_POST["message"] ;
$sendto = "realemail@googlemail.com";
$title = "Feedback Form";

$val = mail( $sendto, $title, $message_from, "FROM: $email_from");

if($val) echo "Email sent";
else echo "Email error" ;

-------------------------------------------------------------------

 

What are the outputs of

Code:

hostname

and

Code:

hostname -f

? My guess is that your server doesn't have a fully-qualified domain name.

 

Hi,

no it doesn't have a fully-qualified domain name, its still in a "test mode".
I will have it connected some-time next week and i will test it again with FQDN.

I just assume that if i can send email using CLI command, i should be able to do a same thing using a php script. Regardless of having FQDN in both cases???

 

I think Google has a problem with your emails if it can't resolve your hostname. Also, if you're sending from a dynamiv IP, you're most likely blacklisted: http://mxtoolbox.com/blacklists.aspx

Maybe you should set up relaying: http://www.howtoforge.com/postfix_relaying_through_another_mailserver

 

INSTRUCTIONS
# Check we have Fully Qualified Domain Name

/bin/hostname

# it should return something like "ispconfig.example.com"
# if not, then we assign a hostname (for example ispconfig):

echo ispconfig.example.com > /etc/hostname
/etc/init.d/hostname.sh

vi /etc/hosts

# and add lines similar but appropriate:

127.0.0.1 localhost.localdomain localhost
192.168.0.100 ispconfig.example.com ispconfig

 

Falko, what about if you get this error with returned mail:

?

if i check hostname it shows ok...
Thank you in advance!

 

Can you check if you use an FQDN in the myorigin directive in /etc/postfix/main.cf?
