Making PHP's mail() asynchronous

Question

I have PHP's mail() using ssmtp which doesn't have a queue/spool, and is synchronous with AWS SES.

I heard I could use SwiftMail to provide a spool, but I couldn't work out a simple recipe to use it like I do currently with mail().

I want the least amount of code to provide asynchronous mail. I don't care if the email fails to send, but it would be nice to have a log.

Any simple tips or tricks? Short of running a full blown mail server? I was thinking a sendmail wrapper might be the answer but I couldn't work out nohup.

Answer 1

Use AWS SES with PHPMailer.

This way is very fast (hundreds of messages per second), and there isn't much code required.

$mail = new PHPMailer;
$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'ssl://email-smtp.us-west-2.amazonaws.com';  // Specify main and backup SMTP servers

$mail->SMTPAuth = true;                               // Enable SMTP authentication

$mail->Username = 'blah';                 // SMTP username
$mail->Password = 'blahblah';                           // SMTP password


$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 443; 

Not sure if i interpreted your question correctly but i hope this helps.
