How can I get the X-Failed-Recipients?

[Daniyal-Javani]

Hello
I want to store email addresses that are failed so I need to get the X-Failed-Recipients, I can see it in email source but how can I get it through php-imap? I try getRawMail but it's not in there.

@Daniyal-Javani do you have an example email (header) or at least the excerpt of it?

All other headers, which are not RFC compliant and not commonly used are retrieved using this piece of code for each single header, which we want:

$header->priority = (preg_match("/Priority\:(.*)/i", $headersRaw, $matches)) ? trim($matches[1]) : "";

See line 572.

So you could do something similar in your application code to get X-Failed-Recipients from the headersRaw:

$mail_header = $mailbox-> getMailHeader($mailId);
$failed_recipients = (preg_match("/Failed-Recipients\:(.*)/i", $mail_header->headersRaw, $matches)) ? trim($matches[1]) : "";
