[#5226] Registration Ajax email checker failure

This issue seems to have reared it's head again. We get the message "Could not check this email: Please double-check: Needed for confirmation." on either front or back end registration. In checking for a solution I have disabled Core Fields Ajax, but it will not disable in the front end.

Any ideas?

That is just a warning that the specific email address being tested cannot be verified most likely because the email server driving it does not allow email checks to complete.

Yes, I am aware of that, but there are several issues when this happens; firstly, all email addresses are receiving this warning, even known good addresses.

Secondly, new registrants are abandoning the registration when they see this message resulting in lost registration sales.

Finally, when I disable the Ajax field plugin, it continues to check all addresses on the front end registration form. Should this not ignore the address check when disabled?

More importantly is why are the addresses not being properly checked? Addresses that are already in the database are being reported as duplicates - so that part of the function works fine. The issue is on all NEW addresses are resulting with this error. It appears as if there is no internet access and the check fails after an extended period of time. But of course access is fine.

Thanks

It's not whether the email is good or not it's whether the recipient mail server responds to MX Record lookup. Google for example rejects all of these so no gmail address will response to these (unless Google decides to change this for whatever reason).

Secondly, new registrants are abandoning the registration when they see this message resulting in lost registration sales.

I think to avoid this we should just return a success message or nothing at all. I do agree the warning is likely off putting to users. Have added a feature ticket for this.

You need to edit the email field within CB > Field Management and disable its ajax validation within Parameters > Validation.

I was concerned that the system was not doing the MX lookup. Even known good addresses(my own) are failing here. However, I have done a direct MX lookup on some of the failed addresses and they have returned an error.

Thank you for escalating.

I would like to keep the Ajax function because without it registrations continue and do not fail until finalized if there is a hard error in the email address. This causes the registrant to repeat the registration process. Most will not and abandon.

Here's what I did in the mean-time:

• Deleted the "Could not check this email: ~" message in default_language.php
• Commented out <!--span class="cb_result_warning"--> in comprofiler.php and cb_core.php

This way the Ajax check still functions to catch hard errors, but does not return the look-up failure message.

Thanks for your help krileon!
