How to validate subscriber data before subscribing to a list

Post by bhcuong2008 » Wed Jul 02, 2014 5:41 pm

Hi,

I take an example for simpler to understand my point.
As we know, we can use this to subscribe user data directly

http://rdir.de/form.do?agnCI=1&agnFN=en ... MAILTYPE=1

Spammers or destroyers can spam the system by executing it repeatedly, may cause the system died.

So my question is how to prevent this? I know I can handle it within action script (for rejecting/allowing subscription). But could you tell me a specific logic for handling this?

Thank you.

Hi,

The links to OpenEMM call OpenEMM forms. If there is no such form, there is no risk.

Here is my suggestion for your problem:

1. Delete the single opt-in form from your OpenEMM installation.

2. Only use double-opt in for your registration.

3. Rountinely update your blacklist using the http://www.mogelmail.de blacklist. This list contains the known fake and temp. email domains. The site is in German, so use Google Translator.

4. To be even more protected against spam registration, you can also include a Captcha in your reg.-form. See below this thread for more on this: http://forum.openemm.org/post8841.html? ... tcha#p8841.

Best Regards
