PHPMailer VS Symfony Mailer

This vulnerability could affect an open-source component, third-party library, protocol, or proprietary implementation that could be used by different products. For more information, please see: https://github.com/PHPMailer/PHPMailer/releases/tag/v5.2.18 ; https://github.com/advisories/GHSA-5f37-gxvh-23v6 ; https://nvd.nist.gov/vuln/detail/CVE-2016-10033

If you don’t have Composer, you can download PHPMailer manually from GitHub and include it in your project.

Step 1: Download and Install PHPMailer Download the PHPMailer library from here and extract it to your project directory.

Then make a form and use PHPMailer.

PHPMailer, as the name suggests, is an email-sending tool for PHP. It offers a straightforward and reliable approach to sending email messages from PHP applications. Security remains a top priority for the PHPMailer creators. It is equipped with built-in support for SSL/TLS encryption, ensuring the protection of email messages against interception and tampering. Moreover, it implements safeguards against common email injection attacks, effectively countering header injection and body injection vulnerabilities.

Have you tried using PHPMailer? mail() really isn't great and ends up being a lot more difficult to use. Phpmailer uses (or can use) SMTP (like Outlook or whichever email app) and is better at HTML and attachments and all that.

I found I have good experiences with a real email address provided by my domain/web host, and then I use the PHPMailer Class to send the message with the appropriate headers and what not.

The easiest way to send e-mails (from a beginner POV) is PHPMailer connected to an existing and configured SMTP server. Does your school has one? If yes, you're all set.

But if you don't mind using composer, the symfony/mailer library is really easy to use and reduces headaches when it comes to sending e-mail. Can be used easily outside of symfony too and I use it for scripts like your own regularly.

Most hosting providers also provide SMTP that you can use, if you have one. Or, there are plenty of online services with a free tier that you can use. Stuff like Sendgrid, Mailchimp, Postmark and SparkPost just to name a few (those services usually provide a SDK to integrate, or can be used with something like symfony-mailer).

That is utterly simple, and can be readily converted for usage with cURL through PHP without loading any external libraries. No symfony/mailer. No PHPMailer/PHPMailer. Nothing.

Symfony Mailer - A powerful library for creating and sending emails.

It is relying on symfony/mailer to send emails and is recommended as replacement for now deprecated SwiftMailer.
