Hello,
I am a full stack developer. I do have prior experience working with PHP, SMTP and Linux servers. I use library PHPmailer library for most of my PHP and SMTP related work. This library is the most popular email sending library in PHP, and a lot of open source projects are using this library.
I would love to discuss your requirements in depth on PM.
I am looking forward to working with you.
Best regards,
Vishal Chitnis
