For the time being, it's advised that current members change their e-mail address to a non-gmail account in order to continue recieving notification e-mails. And new registrants currently validating their accounts are advised to do the same, and re-send their validation e-mail. For those interested, there's a possibility another domain on the same IP has resulted in a Google Mail blacklisting for our domain, and for anyone who knows Google's customer service is basically non-existant. So, getting this sorted out may take a while. I'll update this thread once normal service to Google Mail inboxes resumes. UPDATE: OK, I've made some headway in getting this sorted, and I myself have now started recieving e-mails sent by the board again to my Google Apps & Google Mail accounts. Hopefully, this will be an end to the issue.
