I use a PHP mailer with of my online programs and recently when I look in outlook I see
'crazyphil#host.validns.com on behalf of My Mailer [no-reply#mydomain.com]' when I receive emails from any of my domains.
Previously the crazyphil#host.validns.com was nobody#host.validns:
Return-path: <nobody#host.validns.com>
Received: from nobody by host.validns.com with local (Exim 4.69)
(envelope-from <nobody#host.validns.com>)
It used to be fine like that, but something on my hosts side changed and now I get the 'on behalf of'. Anyone know why this is occuring now, and not before (since all that changed was nobody to somebody!) and how to resolve it?
Thank you,
Phil
Sounds like you need to set the from header in your mailer.
Mail servers will usually append their own if one isn't found.
in normal php it'd be something like
$headers = "FROM: 'fromname' <from#example.com\r\n>";
mail($to, $subject, $body, $headers);
I already had the From in the header, but I overlooked one difference in the header:
Sender: <crazyphil#host.validns.com>
This line popped up in all emails from my host, even those sent by the cron daemon.
Getting this removed resolved the issue.
Thanks though!

I have a website that sends out text messages from the server. I'm using PHP for it:
$headers = "From: " . "Business Name <info#businessdomain.com>" . "\r\n";
$result = #mail( $to,$subject,$message,$headers);
Up until yesterday, the FRM: was always "Business Name" in the text message.
Suddenly, I'm now getting reports that FRM: is coming in as username#173.222.21.166 where username is my actual FTP account username (real IP not provided of course)!!
I definitely don't want to expose my FTP username. Is there something that would determine the FRM: name other than what I have set? I haven't changed the script at all... and suddenly it has changed.
UPDATE: using PHP mail not SMS Gateway
You can add a command line parameters to php's mail function, one of which is from.
mail($to, $subject, $message, $headers, '-finfo#businessdomain.com');
Note the -f directly infront of your from address
This may be related to the mail server on the local machine or the mail configuration on the local machine. There are certain settings, which can prevent faking the FROM header and substituting it by the actual user running the program that sends the mail.
I recommend checking the mail config for php and for the system itself.
I have an odd problem.
I have a 'standard' Email include I use that wraps the php mail() function. This has been in use for a few years and in two places in my site is quite happily sending mail every day. However, on re-using the same include in a different part of the same site on the same host, I am finding I cannot send mail including a 'From' header. The only difference is this new sending location on the site is a basic auth-protected directory.
So before people leap in and tell me this or that, remember, this is the exact same code as it working at the same time on the same host and so the exact-same include works in two locations and not the third.
So I set, among other headers (as this carries multipart HTML Email):
$headers = "From: $fromName <$fromEmail>\n";
$headers .= "Reply-To: \"$fromName\" <$fromEmail>\n";
$headers .= "Sender: \"$fromName\" <$fromEmail>\n";
This works fine in two locations on the site, but the inclusion of the 'From' line causes a mail send failure in a third location on the same host. The code also works fine from my dev machine, it's only the Live hosted box that won't send mail from this third location. Now...
Yes I know I'm using "\n" and not "\r\n", but my experience has been
"\r\n" is necessary on Windows hosts but causes problems on *ix
hosts - and yes I know the RFC says CRLF - and so this is 'fixed'
later in the wrapper if it's on a Windows host but left as "\n" on
*ix
No, setting "\r\n" does not make any difference!
I have experiemented with the mail() fifth paramter and using -f, but that
only gives me mail sent on behalf of
The 'Sender' field actually has the effect that on opening the message the recipient sees; From Pretty_name [email_address], however, in Outlook at least, in the mail list the sender is shown as email_address, not 'Pretty_name'
I've experiented with ini-set, but that only sets an Email address and the message is already going with the desired From Email address, it's the 'Pretty_name' that won't work
So remember - the exact same code is runing elsewhere on the same site without any problems, but the issue here seems to be (for a reason I've yet to fathom) that the same code can only be used without the 'From' header from this location.
Anyone any ideas on what seems such inconsistent behaviour?
Thx
First, if mail() returns false, then make sure you output the last error message:
print_r(error_get_last());
If the error message doesn't really indicate much about the email itself, then it's likely something wrong in the php.ini file (e.g. configuration mistake during an upgrade or something). You can test that by isolating the problem code to a separate file, then temporarily swap out the php.ini file for the default one, restart your web server to let the new php.ini take effect, and run your test again (I'd recommend dumping phpinfo() along with your script so you can confirm that the new php.ini is in effect).
Second, use \r\n. I know it has no functional difference in your test here, but it IS the right line ending and using just \n WILL cause problems in some mail servers that actually follow the rules. When you use \n, you are relying on the mail server to have additional code that handles automatic correction of errors.
Using \r\n might cause problems in some poorly-coded servers that DON'T follow the rules, but that's not really your problem to solve. Always follow the RFC.
I am using PHPs mail() function. I've noticed when going through the message (that gets sent) properties that some headers are present which specify
the filename which sent the email
which version of php I'm running
my OS info
I've removed the domain, but this is basically what's included. How can I stop this being included, or am I just being security paranoid? Also, I would like to keep using phps mail function as opposed to setting up something else. Thanks.

Thanks #Wrikken for pointing me in the right direction
This article highlights two properties in php.ini that can be changed:
mail.add_x_header = Off
expose_php = Off
I have no idea why they'd be on by default..
For ultimate obscuration for all emails sent, you can control the postfix headers on the email server. This also allows you to hide your obscure your hostname. Major wrote a good article that should get you pointed in the right direction. It's a little more advanced, but I think it's the way to go:
https://major.io/2013/04/14/remove-sensitive-information-from-email-headers-with-postfix/
Apart from settings described in this answer
this issue on GitHub suggest removing X-Mailer header like this
$mail = new PHPMailer(true);
$mail->XMailer = ' ';
I am using PHP's mail() function, but I am unable to send mails to the majority of servers.
It send mails to the GMAIL without problems...Probably the rest of servers simply deny my mails...I set the MX records of the mail servers that I need...And I changed my PTR record to mail.example.com......however stil cant send mails..How can I solve this problem?
In addition, messages' sender is displayed as "www-data#localhost"
(I am using Digital Ocean, Ubuntu 12.04)
Errors that I am getting in log file:
My unqualified host name (localhost) unknown; sleeping for retry localhost sendmail[11620]: unable to qualify my own domain name (localhost) -- using short name(errors that I get in mail.err); and in log file it shows some errors regarding verification, Do I need to install smt regarding STARTTLS=client
when using the mail() function ypou neet to set the SENDER as well as teh from/to etc.
i.e.
mail($to, $subject, $body, $headers, "-f ".$webmaster);
The important thing is that "-f ".$webmaster that allows you to override the default of 'www-data#localhost' as the BOUNCE address (Envelope sender) for failed mail..
Most mailers will reject e-mail with an invalid bounce address.
Many hosted servers will not let you set the -f value tho...it sets the 'real sender' and of course its a classic way to send spam..
Try with the -f and if it fails change your hosting company.
Or get yourself a virtual private server.
I had the same problem and one thing you can do is: open a ticket with digital ocean support. By default, new accounts have a block to send e-mails (to avoid spammers). They resolved quickly and greatly improved.
Another thing is: check your mail reputation. You can find some websites that can help with this, like mail-tester.com - This site provides a report with potencial issues to fix the problem.
I am using php5.
Are there some settings or a simple php.ini directive that would redirect all the emails to a folder?
I want on the development machine to have all the emails generated by the system not sent to the actual receiver but put in a folder.
Thanks.
I used to have some code like this (kinda pseudocode):
define ('DEBUG', true);
function send_email($to, $subject, $body) {
if (DEBUG) {
file_put_contents('some_folder/' . $to . date('dmY-His') . '.html', $body);
}else{
// Actual code to send email
}
}
But i agree with others, it's easier/better to setup an development email account to receive those emails.
I don't think you will be able to do something like this. Mails are sent by a mail server so it must be your mail server that writes them to a file instead of sending them.
Why not simply send it to a special development email?
Sample:
define('DEBUG', true);
if(DEBUG)
{
// Override recipient
$recipient = 'development#domain.tld';
}
// Send mail...
No settings that I'm aware of in PHP itself. However, if you're using Postfix on your development server, here's a recipe I cooked up to redirect all outbound email to a single (local) address:
/etc/postfix/main.cf: (add this to the existing file, don't replace everything)
virtual_alias_maps = regexp:/etc/postfix/virtual
/etc/postfix/virtual:
/.*/ duskwuff#localhost
You can configure your mail server to accept SMTP messages as normal, but make it unable to forward them onto another mail server. If your mail server supports it, make it redirect all messages to a postmaster account, or any other address of your choice.
This means that PHP will behave as normal, everything will appear to work straight away with the message, but it just won't go to the 'intended' recipient.
It also means that you can inspect headers (pretty much as they would normally appear), to support debugging.
There are many ways to do this. Basically, you need to define the sendmail command in your php.ini to point to a program or script which will save the mail locally.
One solution is this:
Catch emails with php script
Another is this:
Mail catcher
