Importing Emails in Bulk creates unique error involving recognized TLDs

[AmandaB547]

We've created an application that assists users in quickly building landing pages. They then have the option to migrate the information they've gathered in bulk into several locations. We have hit a snag with the Constant Contact API. We get an error saying that the TLD of a particular email is invalid.

The problem with this is that the error then causes the entire process to abort and nothing gets imported. Searches through the developer forums have yielded no answers to this problem other than "we have an approved list of TLDs." However that list can not be found.

Any suggestions on how we:

a) work around this issue

b) get our hands on the approved list of TLDs

Thanks!

We recently discovered a defect in our email address validation service that is incorrectly flagging email addresses as invalid.  We're working on getting a fix out to production ASAP.  We do currently support the major TLDs (.com, .co, .org, .edu, etc.) so this should be fairly low impact to developers while we get this resolved.  This is only affecting more obscure TLDs.
