Mail SPF Checker for Laravel

The Laravel Mail SPF Checker is a package to check if you can send an e-mail through a given mail server in the name of a given e-mail address:

When sending in the name of a domain without using the legitimate mail server of the domain it can get tricky...Most of the time your mail ends up in a spam folder. This can be solved by configuring a correct SPF record for the domain you are sending with.

This package provides a checker that you can use in your app to ensure you have a correct SPF record:

$mailSpfChecker->canISendAs("hello@dietse.dev"); // bool
 
// If you cannot send mail correctly, this will output the needed SPF record:
 
if (! $mailSpfChecker->canISendAs("hello@dietse.dev")) {
    // Generate a txt-record with a name of dietse.dev
    // and the value v=spf1 ip4:#.#.#.# -all
    echo $mailSpfChecker->howCanISendAs("hello@dietse.be");
}

You can also check using a given mail server:

$mailSpfChecker
    ->using('SMTP.mandrill.com')
    ->canISendAs("hello@dietse.dev");
