Please explain this error message;
Postman: wp_mail has been declared by another plugin or theme, so you won’t be able to use Postman until the conflict is resolved.

wp_mail is declared by core.
It is used by Contact Form 7 (amongst others)

So I don’t understand what your error message is telling me.

So my problem at the moment seems to be;

Postman is working: sends test message.
It does nothing with Contact Form 7 5.1

OK, good news and bad news.

Good news is I’m sending emails now using a round about way of replacing PHP mail() with SMTP service by manipulating PHPmailer using this code;

add_action( ‘phpmailer_init’, ‘wizcom_phpmailer_init’ );
function wizcom_phpmailer_init( PHPMailer $phpmailer ) {
$phpmailer->Host = ‘mail.actionlearningassociates.co.uk’;
$phpmailer->Port = 25; // could be different
$phpmailer->Username = ‘[email protected]’; // if required
$phpmailer->Password = ‘#DUX5201eve’; // if required
$phpmailer->SMTPAuth = true; // if required
// $phpmailer->SMTPSecure = ‘ssl’; // enable if required, ‘tls’ is another possible value

$phpmailer->IsSMTP();
}

My understanding is that this is what Postman should have been doing. So the bad news is that Postman won’t do this when Contact Form 7 is being used. Although it is, apparently doing it when it’s test email is sent.

But why not, surely in some way this what Postman SMTP is/should be doing?
Who owns this problem Postman SMTP? or Contact Form 7?

Hello Chris.

wp_mail is a WordPress function to allow WordPress, themes and plugins to send email.

WordPress provides a default implementation of wp_mail. But WordPress allows email plugins (like Postman) to provide an alternate implementation of wp_mail.

This message is Postman telling you that some other plugin beat it to the punch. Only one plugin may handle email delivery. However, you may also see this error if any plugin on your system directly includes the file pluggable.php – a lazy hack some plugin developers use to access WordPress code/libraries.

patched pluggable.php

Patching pluggable.php is definitely not the recommended solution; removing the conflicting plugin is.

Having said that though, it appears your problem is related to Contact Form 7. If Contact Form 7 and Postman were talking, you would see the activity in Postman’s log file.

Postman does not manipulate PHPmailer; Postman actually replaces PHPmailer with zend_mail. This is why Postman is able to offer OAuth 2.0.

Sounds like Postman’s original warning was correct then; there is another plugin preventing Postman from taking over wp_mail.
