Hi guys.
I won't ask is that possible - though certainly it made me
frown - because it's happening.
Everywhere - so far - I emailed, including usual suspects,
eg.: gmail, yahoo, etc. I got _pass_
Now I get bounces - only from this one place/destination -
saying:
This is an authentication failure report for an email
message received from IP
xx.yy.zz.aa on Sun, 15 Feb 2026 09:05:58 -0600 (CST).
Feedback-Type: auth-failure
Version: 1
User-Agent: OpenDMARC-Filter/1.4.2
Auth-Failure: dmarc
Authentication-Results: mail.some.net; dmarc=fail
header.from=MY.domain
...
dkim=fail reason="signature verification failed" (1024-bit
key) header.d=MY.domain [email protected] header.b=EFnQn
...
and I only wonder - could it be not me but someone in "between"?
That IP I "obfuscated", is not mine.
This a popular, I think, mailing list and since I'd like to
be able to mail to them, I wonder - in case it's me - if
there is anything I can do.
all advices are much appreciated.
thanks, L.
