A Laravel package to check if your application can send e-mail in name of a given address.

Most of the web applications are sending mails. Mostly through a local mail server or an external mailing service.
When sending in name of a domain without using the legitimate mailserver 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 gives you the possibility to check if you can send with a given from address using the mailserver specified in your mail config or a given mailserver. It also gives the possibility to retrieve a dns txt record to configure your dns.

This package can be installed in Laravel 6,7,8,9 and 10

composer require dietercoopman/mailspfchecker

    if ($mailSpfChecker->canISendAs("hello@dietse.dev")) {
        // the happy path
    } else {
        // you can not send e-mail in name of hello@dietse.dev, but I can tell you what to do  
        echo $mailSpfChecker->howCanISendAs("hello@dietse.be");
        // Generate a txt-record with a name of dietse.dev and the value v=spf1 ip4:#.#.#.# -all
    }

    if ($mailSpfChecker->using('smtp.mandrill.com')->canISendAs("hello@dietse.dev")) {
        // the happy path
    } else {
        // you can not send e-mail in name of hello@dietse.dev, but I can tell you what to do  
        echo $mailSpfChecker->using('smtp.mandrill.com')->howCanISendAs("hello@dietse.be");
        // Generate a txt-record with a name of dietse.dev and the value v=spf1 ip4:spf.mandrill.com -all
    }
