Validate Email Domain 1.0.0

[Kirby]

Kirby submitted a new resource:

Validate Email Domain - Checks if the domain-part of an email can be found via DNS - if not the email is rejected as invalid

This really simple Add-on checks if the domain-part of an email is "valid", eg. if the domain can be found via DNS - if not the email address is rejected as invalid.

Validation is done via the bundled version of https://github.com/egulias/EmailValidator

Well ... yahoo.com is a valid domain, isn't it?

Try a nonexistent domain like foo@non-1234-existent-45-domain.com

Nice add-on. Does it check the domain's DNS record for a valid MX record?

I just bought it ! It exists now.

@Unique Username
All the Add-on does is to use the (already bundled) DNSCheckValidation class.

To be honest, I didn't check what validation it does exactly

Presumably it does check MX/A/AAAA.

Ahh I see, I appreciate the reply. And again great work putting it into an add-on

This addon requires PHP 8.1 and PHP Intl?

Thanks! ...and my server logs thank you. XenForo undeliverable emails, including all the continued attempts to re-deliver to non-existent domains will no longer pollute the logs.

Suggestion: Do you think it might be better to do the DNS check after the email input goes from in focus to out of focus rather than waiting to check after the register button is clicked?

Intl is most likely required, PHP 8.1 is not required.

This night be a bit more userfriendly, but unlike the current approach (which is only a really simple extension of existing functionality) it would require quite a bit of new code.
Not sure if I'd be willing to do that

@Kirby the top-level domain check is case sensitive. So example@localhost will fail, but example@lOcalhost will pass the static list check. The DNS check should fail, so it isn't a huge issue.
