Strange SpamAssassin/filtering issue

Hello.

We have a server in the office that is running cPanel and has a large number of domains on it. I am having a weird problem with spam filtering and need some assistance, please.

(Bear in mind the following domain names are made-up for privacy reasons)

When anyone from senderdomain.com sends to certain domains on our server, it ends up in spam. With other domains, it goes to the inbox as it should.

[email protected] wasn't getting through to [email protected] or [email protected] even though I had specfically whitelisted the email address and the entire domain in SpamAssassin. Still goes to the spam folder. I then created a temporary email address on another domain on the same hosting server, [email protected]

When sending the exact same email from [email protected] to the above addresses, it goes to spam on the recipientdomain1.com and recipientdomain2.com accounts, but goes to the inbox on mailworkshere.com even though on all three domains the email is not flagged as spam.

Please see below mail headers, I had [email protected] send one email to the three above recipient addresses. As I said before, with [email protected] and [email protected] the email ends up in the spam folder even though [email protected] and *@senderdomain.com are whitelisted and the spam score is good. [email protected] receives the same email in the inbox as it should.

I cannot fathom why this is happening, and what I can do to get mail from [email protected] to not end up in the spam folder.

I have included mail headers from an email sent to all three addresses, can somebody assist me with this please? I'm hoping there is something obvious and stupid I have overlooked that would be causing this.

Thanks!

Hello :)

The message logs you provide indicate the message was not detected as SPAM. Could you open a support ticket using the link in my signature so we can attempt to reproduce this issue or further review the mail logs to determine why emails are placed in the "SPAM" folder when SpamAssassin does not detect them as SPAM? Please post the ticket number here so we can update this thread with the outcome.

Thank you.
