Fix mail headers on signup, credit granted, etc. to include the "Date" mail header
This header is required by RFC2822, etc. and may lead to your mails being flagged as spam by SpamAssassin and other spam filters.
Will review the mailing on support tickets to get that cleaned up.
The emails when *I* update a support ticket are still getting caught by my junk filter but when staff reply they are not. In this case I consider this a feature: I don't want to get an email when I reply. Please add email notification settings to enable specific mailings only.
It should be added now and processed on all future mailings.

After receiving a few e-mails through GMail we eventually see some e-mail from DO get filtered. It doesn't happen as often as of late, though it does still happen occasionally. Next time it happens, I'll check and see what pops up - all the older e-mails have already been flushed.
Is there a comment on the filter which says why it was tagged as spam?
On a related note, all emails I get in regard to support ticket responses go straight to my junk folder.
