As a workaround, remove mail-tester.com from vendor/vboctor/disposable_email_checker/data/domains.txt

That's worked perfect, thanks.

@vboctor do you think we should introduce a configuration option to disable the checking?

That info was helpful. As a paying client of sneakemail.com (snkmail.com) for over a decade, I'd like to note here that they are a reputable, for-fee service, and extremely vigilant about how their service is used. Spam and other abuse through their servers is not tolerated. I recommend removal of those domains from the list, but understand that for those who don't know the service that it's just one of a huge list of companies in this category.

Peter, is there a reason why a service like https://mailtrap.io can't be used for testing?

@Starbuck It seems that the domains you mentioned are marked as disposable on other providers and hence there made their way into my disposable library. Here is kickbox.io API results for the domains you mentioned:

• https://open.kickbox.io/v1/disposable/sneakemail.com
• https://open.kickbox.io/v1/disposable/snkmail.com

@vboctor - that is correct, This is a service which provides disposable emails. My note here is that it's a reputable service, not a problem source. As an example, a pharmacist sells drugs, and so does the guy on the corner, but we shouldn't lump them all into a single list of "drug dealers" - and a gun dealer sells weapons for self-defense, which is not the same as the guy on the corner who sells guns.

I occasionally find my email addresses blocked by sites that use these global lists. While called "disposable", I never dispose of these addresses. Like someone who buys a gun for protection, I use them to protect myself against spam from sites, and I keep them for all sites at which I am registered. I pay for the ability to delete these addresses if I unregister from a site and continue to get emails from them, or if I find some site owner has shared my address with some other entity. In this world where a "privacy policy" is just a legal statement that we have no privacy, this is a form of consumer protection. My "drug" here (in the form of a disposable address) keeps me safe from abuse, where similar "drugs" used by spammers are being abused.

So with that in mind, I encourage you to remove this one service (two domains) from that list which otherwise seems to be quite effective for its purpose.

You could suggest that I take this up with kickbox.io. But I don't use their services, I use MantisBT. And I'm here to ask the stewards of MantisBT to correct an error that's been made by an upline provider. If I have time one of these days I'll do what I can elsewhere. But I'm not in the business of evangelizing justice for services like this - I'm just trying to fix this one situation because we're in the right place to do it.

Thanks.

I used http://www.zerobounce.net and it is an amazing platform for online email validation that is created to ensure companies avoid email bounces. This is accomplished by identifying invalid, abuse, spam-trap, and other hard bounce email addresses. They also provide a real-time API for email verification on your platform.

If you are looking for a way to determine if an email was generated by a disposable email service, then you should try https://www.datavalidation.com/ With their service you can upload a list of emails and find out which are deliverable as well as if it is a role-based email or a disposable email.

Vboctor/disposable_email_checker (https://github.com/vboctor/disposable_email_checker/blob/master/data/domains.txt) - has very old database, last update 2 years ago.
Domain "ukr.net" is recorded in this database despite the fact that it is a very popular, trusted and reliable postal service in Ukraine. I have users with email in domain @ukr.net and they cannot register by themselves.
To make changes to file vendor/vboctor/disposable_email_checker/data/domains.txt - bad way, after each new update MantisBT version I need to update this file manually.

Please delete check vboctor/disposable_email_checker or replece it with another project (example martenson/disposable-email-domains https://github.com/martenson/disposable-email-domains).

P.S. https://open.kickbox.com/v1/disposable/ukr.net return {"disposable":false}

@Dabin I have removed ukr.net from the list of disposable domains.

@atrol I have updated the latest code of disposable library to support add_domains(array) and remove_domains(array). Which enables consumers to white list or black list their own domains. If we want to support this in MantisBT, then we will have to expose it in configs and integrate latest disposable library (not yet released).

@vboctor - thanks! In the new version of MantisBT, the ukr.net domain will no longer be blocked?

@Dabin ukr.net domain will no longer be blocked starting from 2.19.0, see 0024988
