I often send emails out via SMTP using PHPMailer and everything works very well. However, I need to send some emails using an SMTP Proxy, which I understand PHPMailer doesn't support.
It's quite hard to find out information on this, as I keep finding issues with sending emails from behind a proxy, rather than using a proxy server. However, I think that PHP doesn't support SMTP proxy servers either?
My questions are...
Using PHP, is it possible to send emails using an SMTP proxy server?
If so, what is the process?
Thank you in advance!
