Finding out Rejected Addresses in Cc and Bcc also - how to? - php

Question

I can find out rejected addresses within swiftmailer from the ->setTo(array(. With the following code:
$mailer = Swift_Mailer::newInstance( ... );
$message = Swift_Message::newInstance( ... )
->setFrom( ... )
->setTo(array(
'receiver#bad-domain.org' => 'Receiver Name',
'other#domain.org' => 'A name',
'other-receiver#bad-domain.org' => 'Other Name'
))
->setBody( ... )
;
// Pass a variable name to the send() method
if (!$mailer->send($message, $failures))
{
echo "Failures:";
print_r($failures);
}
/*
Failures:
Array (
0 => receiver#bad-domain.org,
1 => other-receiver#bad-domain.org
)
*/
Now I want to find out rejected addresses from Cc and Bcc fields too. How can I add similar code? Is there a tutorial or a workaround? There is no example in the swiftmailer tutorial.

Answer 1

You can use a try-catch block where you set the to, cc, and bcc email addresses.
From the manual:
If you add recipients automatically based on a data source that may
contain invalid email addresses, you can prevent possible exceptions
by validating the addresses using Swift_Validate::email($email) and
only adding addresses that validate. Another way would be to wrap your
setTo(), setCc() and setBcc() calls in a try-catch block and handle
the Swift_RfcComplianceException in the catch block.
So you can use the try-catch on $message object:
$message = Swift_Message::newInstance();
$emails = array(
'receiver#bad-domain.org' => 'Receiver Name',
'other#domain.org' => 'A name',
'other-receiver#bad-domain.org' => 'Other Name'
);
// loop through emails and set the individually to catch exceptions
foreach($emails as $email => $name)
{
try {
$message->setTo(array($email => $name));
} catch(Swift_RfcComplianceException $e) {
echo "The email ".$email." seems invalid";
}
}
// And do the same thing with cc and bcc emails
$ccEmails = array(
'receiver#ccemail.org' => 'CC Receiver Name'
);
foreach($ccEmails as $email => $name)
{
try {
$message->setCc(array($email => $name));
} catch(Swift_RfcComplianceException $e) {
echo "The email ".$email." seems invalid";
}
}
You could set the failures to a variable if you depending on how you want to handle them.
Edit: If you have an array of users with separate first and last names you can user the below:
$users = array(
array('email' => 'receiver#bad-domain.org', 'first' => 'Receiver', 'last' => 'Name'),
array('email' => 'other#domain.org', 'first' => 'A', 'last' => 'name'),
array('email' => 'other-receiver#bad-domain.org', 'first' => 'Other', 'last' => 'Name')
);
// loop through users and set the individually to catch exceptions
foreach($users as $user)
{
try {
$message->setTo(array($user['email'] => $user['first'].' '.$user['last']));
} catch(Swift_RfcComplianceException $e) {
echo "The email ".$user['email']." seems invalid";
}
}
