@mxg,
@bwillia1 I apologize for the inconvenience. Despite our very careful approach with delivering new updates, complexity of such task is still leaves room for errors. As you noticed, we experienced another delay with sending or receiving emails, this time is due to the fact of someone send email with incorrect recipient in 'To' field, where our email validator get stuck causing all new emails put on hold.
No emails get lost, it just a '2 a.m' error. Unfortunately our budget prohibit us from keeping 24 live server supervision. However we promise to troubleshoot and fix bugs in very fast manner.
Issue is resolved, and server is catching up with emails right now.
Thanks again for your patience.
