It looks like our email took a dump in late January 2018. We've fixed the issue by getting rid of systemd. There are a flood of emails going out (over 7,000) so for all VIP members and new site users - we apologize for the delay. Our systems administrator typically checks on these things once a month so it happened after our mid month check in January and wasn't caught until the check in February.
Please let me know if anybody has any issues.
