My apologies for posting here a lot but we are still wading through the 2.4.8 to 188.8.131.52 upgrade and are grateful for this community’s support. Here goes the latest:
We’ve enabled Email Registration to our OJS instances and recently added ReCaptcha. While it’s unclear if these are related, following adding ReCaptcha we started receiving hundreds of bounced emails titled “Validate Your Account”. We’ve investigated a number of the email addresses and found that they are being generated whether or not the user has successfully completed registration. I’m reluctant to include the full text of the message for security reasons but have tried to include some of the basic elements with dummy/redacted info. I could email a copy of this to a PKP developer if needed. Any help with this would be greatly appreciated.
