Yikes!  A bunch of legitimate emails are being rejected for 'non-existent domain in From:'  In this example, a Gmail test message (from me!) is wrongly rejected:

21:43:11.262 2 SMTPI-000003( [2510010] received encrypted, 2832 bytes
21:43:44.000 1 ENQUEUER-000006([2510010]) [2510010] rule(DMARC-scan): filter(DMARC-scan) report: non-existent domain ( in From:
21:43:44.000 1 QUEUE([2510010]) Enqueueing failed. Error Code=external filter rejected the message
21:43:44.000 1 DEQUEUER [2510010] SYSTEM(gib) failed: non-existent domain ( in From:
21:43:44.853 2 SMTP-000004(*) [2510011] sent encrypted []:50033 -> []:2501, got:250 4126316 message accepted for delivery

The From: line contained [my correct Gmail address]

Some mail does come in, but what’s up with this?!  It just started spontaneously a day or two ago, but isn’t consistent.  I can’t think of any changes I’ve made recently, same DNS servers, and I tried Refresh…any insight?  Cheers,
