Warden Posted April 5, 2023 Share Posted April 5, 2023 The personal copy of an outgoing report I received today arrived with “[SUSPECTED spam]” injected into the subject line: X-IronPort-Anti-spam-Filtered: true Subject: [SUSPECTED spam] [SpamCop (80.94.95.83) id:7253373020]Re: lening X-IronPort-AV: E=McAfee;i="6600,9927,10671"; a="288091" X-IronPort-AV: E=Sophos;i="5.98,321,1673942400"; d="scan'208,217";a="288091" Received: from vmx.spamcop.net ([184.94.240.100]) by esa2.spamcop.iphmx.com with ESMTP; 05 Apr 2023 06:55:44 -0800 Is this expected? I’m surprised to see SpamCop marking its own outgoing mail as spam. Quote Link to comment Share on other sites More sharing options...
Lking Posted April 5, 2023 Share Posted April 5, 2023 Check with your email app, security app. For example depending on your settings, Thunderbird or Norton can insert that type of warning into the subject line of what they suspect to be spam or a scam. I have been getting [SUSPECTED scam] inserted into the subjects of followup emails from stores I have bought something from when they include survey questions. All part of efforts to protect us from ourselves. Quote Link to comment Share on other sites More sharing options...
gnarlymarley Posted April 6, 2023 Share Posted April 6, 2023 Also, check for a rule for spam filtering software. Spamassassin (cpanel) can add something like that too if it thinks that spammers actually put "spam" in their hostname. Quote Link to comment Share on other sites More sharing options...

petzl Posted April 6, 2023 Share Posted April 6, 2023 27 minutes ago, Warden said: What is your interpretation of the headers excerpt I provided? Don't mean it is SpamCop's IronPort server stamping "[SUSPECTED scam]" in subject line! I get a lot email forwarded through SpamCop's email server never happened to me, including real spam. Gmail do stamp malicious email SpamCop does not filter for spam!https://ibb.co/RcJbTNY Quote Link to comment Share on other sites More sharing options...
gnarlymarley Posted April 12, 2023 Share Posted April 12, 2023 (edited) I think we need to clarify if you are running ironport at your email host and if were you indicating that it could be that ironport that is adding it. From what I can see from the headers, it was added after vmx.spamcop.net send it on its way. Something added it after.

RobiBue Posted April 15, 2023 Share Posted April 15, 2023 (edited) Since April 1st I am receiving the occasional spam report (the ones I send to myself from spamcop) which has the [SUSPECTED spam] marking added to the front of the subject line. I have the feeling that IronPort (SpamCop/Cisco) itself is adding that stamp, since it is coming directly from there. I get my mail through google, and only a few of the spam reports since 20230401 have that stamp, and only the spam reports. Not the spam, not other emails, and not even "suspected spam". As you can see, everything [SUSPECTED spam] is (in my case) added to some reports from SC.

Lking Posted April 15, 2023 Share Posted April 15, 2023 Every email application, host, ISP between the source of an email (IronPort) and your screen can, and does modify the header of a received email. It does not make much sense to me, for SpamCop to generate an email to you AND mark the subject line as [SUSPECTED spam] Sense the beginning of time, different ISPs/email apps have marked or blocked email from @spamcop.net as spam. There have been several reasons; some as simple minded as the word 'spam' in the domain name. SpamCop emails also include links which include the work 'spam'. Other links may be to domains that have been identified as sources of spam. Quote Link to comment Share on other sites More sharing options...
RobiBue Posted April 15, 2023 Share Posted April 15, 2023 (edited) and just now, I did another search in my history and found that back in 2009, a mail list running Barracuda had exactly the same add-on. The list manager did remove it "I believe I've turned off the subject mangler." 😁 but that was in 2009...

RobiBue Posted April 16, 2023 Share Posted April 16, 2023 I know that it doesn't make sense, but there is no other explanation... (and also sorry for this "very long dissection")TL;DR: IronPort mail server changes the Subject: line. Somehow end of March, SpamCop's servers were moved (at least that's what I understood) and the new flow of reports goes through a different set of mail servers (or at least one additional set.) Here's one I took apart which is the first [SUSPECTED spam] in over a decade (back between November 2008 and April 2009 I received a few like that marked by Barracuda but it caused more headache than good so the list manager fixed the spam filter to disable the "subject mangler") Now just to clarify: this is not the one from back in 2008/9; this is the first one I received like this on April 1st.

At least these are my findings, so I have a very strong suspicion that Cisco added an extra "outgoing layer of security" to the handling of the emails, and unfortunately, since they "are spam ", they get flagged...

Statement from my mail provider: “We don't make any changes to the content or existing headers of the email, so the [SUSPECTED spam] was definitely not added by us.” 0.06% of my mail contains the header X-IronPort-Anti-spam-Filtered. Of that, 40% is from government offices and 60% is from SpamCop, with all of the latter dated since 2023-03-31. Quote Link to comment Share on other sites More sharing options...
gnarlymarley Posted May 23, 2023 Share Posted May 23, 2023 (edited) I had this happen twice and both times the message passed through 68.232.143.151 from vmx.spamcop.net. One was a reply from the sent report and the other was a reply from a submission. Looking at the headers, it appears that 68.232.143.151 is adding the "[SUSPECTED spam]" to the subject line. Now 68.232.143.151 has nothing to do with my email provider and does appear to be on rotation for outbound spamcop email being handed off from vmx.spamcop.net. It is a Cisco IP and I suspect that they might be filtering some outbound SpamCop communication through their IronPort scanner device.
