Yahoo incoming mails with DMARC_REJECT = 10

[CedricCQ]

Hi,

For the past few weeks, I've been having problems with incoming e-mails from Yahoo.

PMG is putting them into spam, when they are not.

When I open the information about the spam, I see that there is a DMARC_REJECT that adds 10 points to the spam score.

What can I do about this?

Thank you very much for your help!

What is your maximal spamsize setting? - another user had a similar problem and fixed it by raising it to the mail size_limit - https://forum.proxmox.com/threads/dmarc_reject-10.62135/

I hope this helps!

Hi,
The mail addresses from yahoo.com were returning due to the blacklist. https://forum.proxmox.com/threads/where-is-directory-configuration-mail-proxy-whitelist.63099 I've added whitelist to all yahoo ip addresses via this header. I didn't make it to the outgoing side yet.

Hi,

It seems to be good.

Increasing the max spamsize did the job !

Thank you !

What is the correct size for spamsize? Becasue I set up it 502144 and the problem persists. Thanks

I had it set to 10'000'000 bytes and the problem was gone.

We use to size 962144bytes. Do not problem.
