  • array $params - a array of backend specific parameters.

    List of parameter for the backends

    • mail

      • If safe mode is disabled, $params will be passed as the fifth argument to the PHP mail() function. If $params is an array, its elements will be joined as a space-delimited string.

    • sendmail

      • $params["sendmail_path"] - The location of the sendmail program on the filesystem. Default is /usr/bin/sendmail.

      • $params["sendmail_args"] - Additional parameters to pass to the sendmail. Default is -i.

    • smtp

      • $params["host"] - The server to connect. Default is localhost.

      • $params["username"] - The username to use for SMTP authentication.

      • $params["password"] - The password to use for SMTP authentication.

      • $params["localhost"] - The value to give when sending EHLO or HELO. Default is localhost

      • $params["timeout"] - The SMTP connection timeout. Default is NULL (no timeout).

      • $params["verp"] - Whether to use VERP or not. Default is FALSE.

      • $params["pipelining"] - Indicates whether or not the SMTP commands pipelining should be used.

I was having trouble with XVERP being added in the SMTP connection even though $params["verp"] was FALSE.

The fix is to NOT set $params["verp"] at all, either unset it or just don't specify it in your $params.

$params["verp"] = FALSE; // comment out this line if you see an XVERP error
$params["debug"] = TRUE;
...
$smtp = Mail::factory('smtp', $params);

Calling $smtp->send() gives the following debugging:
DEBUG: Send: MAIL FROM:<---@---.com> XVERP
DEBUG: Recv: 555 5.5.4 Unsupported option: XVERP
DEBUG: Send: RSET

PEAR::isError($mail) outputs:
Failed to set sender: ---@---.com [SMTP: Invalid response code received from server (code: 555, response: 5.5.4 Unsupported option: XVERP)]

If you are using 'mail' as your backend and you want to set your Return-Path you can do it like:

$mail_object =& Mail::factory('mail', '-f bounce@domain.com') ;

Then later if you need to change it you can

$mail_object->_params = '-f bounce2@domain.com' ;

This is useful if you use a function to send your email since you can't create a new reference to the factory inside a function. But keep in mind that your new _params will be used for all subsequent calls to your $mail_object. So you may want to manually set them every time you send an email.

If you are using the smtp backend and an SMTP server that requires authentication and you want to use a method other than PLAIN or LOGIN (such as CRAM-MD5) you'll need to make sue you've got Pear's Auth_SASL package installed as well, as it isn't made obvious from the error messages that Mail returns why it's failing!

Set headers for UTF-8:
$headers['Content-Type'] = "text/plain; charset=\"UTF-8\"";
$headers['Content-Transfer-Encoding'] = "8bit";

Still can't figure out how to send proper UTF 8 emsils.... any ideas?

the persist value should be TRUE or FALSE. it's not clear on the page.

if you are getting the error:
Failed to connect to smtp.example.com.br:25 [SMTP: Invalid response code received from server (code: 421, response: 4.7.0 smtp.example.com Error: too many connections from your_ip)]

try to get this option to TRUE.
Note by: Joe
There is hard-coded -f option in Mail_sendmail->send so it is impossible to set it using $params['sendmail_args']. It is hard-coded to -f$from.

In my case it caused 'X-Authentication-Warning' in mail headers.
Note by: shaun@shaunfreeman.co.uk
When sending mail via smtp be careful with the $params["auth"] option, the docs say it set it either to true or false, but in my case this didn't work and only when I set it to the actual authentication method of the server it worked. In my case I had to set it to:

$params["auth"] = "PLAIN";

This little problem had me going around in circles for 2 weeks!
