Issue DMARC issue with forward mail

Sergio Manzi said:
Yeah.. I guess the Sendgrid thing is at least "suspect"

But the fact that you have to turn off DMARC for the locals to get mail is not right. We must understand if that "missing piece" of yours in /etc/postfix/master.cf can explain this and why you don't have it...

Pinging my pal @Mark Muyskens ... :) Do you have that piece of cr** in your Postfix config?? Do you know what's that for??

dis is mine;

https://markmuyskens.com/master.cf

although, this server is hosed. I'm about to wipe and reinstall. i'll compare and see if it's the same with a fresh install.
 
Well - meant to install 17.8 first but wasn't paying attention so ended up with a clean 17.5 install that doesn't have the entry, Upgrading to 17.8 added it in.

Even better, Mark! Now we know for sure where it does come from! Thanks! :)

... and we know for sure that I can't compare my logs with those from @Giuseppe and @G J Piper
... and we know for sure that we are between a rock and an hard place

Thanks Mark, appreciated, but TBH I'm thinking about launching a temp VPS on DO, but with 17.5.3 to put me in the same exact conditions as @Giuseppe and @G J Piper
Only problems I have are:
  • time. I'm quite busy with other stuff ATM...
  • a license. I know with 17.8.11 you can get a temp license (although I haven't yet looked "how"), but I don't think this is possible with 17.5.3, correct?
 
Give me another 20, I'll take it back to 17.5. No added costs to me, it's spare resources.
 
Fantastic, thank you!
Can you put this in .ssh/authorized_keys, please:
Code: 
ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAQEAijgcA+/R0/hpPxtpYh/d4q9etuxMLeoSQC6yZuJ2I1PcHOj+1zn7euIhnXEXyCaL6B4M2JwbXJxcQKmYIVYD7CIlzOhK2WNCSm9C6bvt2x8ScncNyc2XqC5FUthFvRJqs9SEYrf+ogJ/RAPVaZXIwLBSxrptEg9cM4F09ebDiEa9U/BTVWfmQ7/ggp2lugMEJp+xELvRfH59/MrvdCmU/B/FeOawM0s6NSXJA3eFTLt8JLVejCoohOQetjvrN+tOyIf4OPsFkxoV+hlOINh5taPn1hY4InZ3QvrBNxFAAL5DSVLDXachtT3ln6sCSF09GEISL3FvRFIPg8KMComkZQ== smz DigitalOcean

how do you do DNS?
may I change it and install the DO DNS Extension?

Should be up now.
I just have a cheesy free domain on there. You can go with DO, doesn't matter :D

@Giuseppe and @G J Piper : bad good news for you! ;)

EVERYTHING (I mean, the whole enchilada of forwards, with all the DKIM/SPF/DMARC checking turned on...) on a fresh 17.5.3 #43 installation!
True, @Mark Muyskens ?

I'm out of ideas ATM...

@G J Piper yours might be due to the relayer...
@Giuseppe , yours can be because of the rDNS and MX being... questionable...

I don't know... those are just guesses...

:(
