Probs with "disposable email" - is it possible to check before registration

Hi together,
since i give some goodies for my newsletter registration i have a lot of problems with disposable email addresses.
Is there a possibility to check the email addresses before registration to prevent registrations with disposable email addresses ?
Found only a old plugin (Compatible with version 2.11.10)

I´m using version 3.2.1.

When there´s no way to do it in the standard, where´s the best location in code to add my own php function ?

thanks for help

@RalfB The plugin should work with phplist 3.

Hi duncanc,
thanks a lot again for your help :slight_smile: will try it during the next days an will give feedback here when i have success
