1.6 FORGED_MUA_MOZILLA Forged mail pretending to be from Mozilla
I am sending from Thunderbird. So it's coming from Mozilla. But it is not
forged mail pretending to be from Mozilla.
What is triggering this?
meta FORGED_MUA_MOZILLA (__MOZILLA_MUA && !__UNUSABLE_MSGID &&
!__MOZILLA_MSGID)
It doesn't believe the Message-ID was generated by Thunderbird. What's the
message ID?
Thanks. That makes sense. But it just adds to my problems. I am pulling
my hair out on trying to get a clean send that gmail, outlook, and others
will accept. I have an Apache JAMES server. When I send to mail-tester.com I
get a 10 out of 10 clean bill of heath. But gmail, outlook, and a bunch of
other MTAs won't accept it and bounce it back (with no reason attached). I'm
hosting on AWS. So the recommendation was to proxy my outbound mail through
AWS's SES server so it appeared that the mail came from 'trusted' Amazon.
Now I realize that Amazon changes the message id, and I get this 'forged'
flag.
It's possible that the rule needs an exception for that case. Would you
zip up a sample for me in private mail, with all headers intact?
I'm delivering mail for a very large company where unsuccessful mail
delivery to the recipients can be catastrophic.
So, gmail etc. are rejecting the messages from your James server? Or is
this a broader issue with general email? If you like, you can send some
test messages to me directly and we'll see what happens.
