Thunderbird did not put it there either. Your antivirus or your providers scanner software did. Example: http://forum.mhelpdesk.com/knowledgebase/articles/632572-what-does-disarmed-in-the-subject-of-emails-sent-f

My problem isn't identical, but it's probably related.

Virtually everything I send from Thunderbird ends up with some variant of this in the subject line:

[Norton AntiSpam]RE: [Norton AntiSpam]

Now the easy answer, which would be wrong, would be to say that Norton does this, and not Thunderbird. The problem with that theory is that I have a large number of messages that get sent to both Thunderbird and Outlook.

When the messages show up in Outlook, they don't have this clutter. When the identical message shows up in Thunderbird, it does have this clutter.

So, it's not a "Norton Problem". It's an interaction problem that includes Norton and Thunderbird. This interaction problem does not occur with Norton and Outlook.

Suggestions?

Thx,

Thunderbird does not modify a subject line, ever. Keep looking.

Maybe you could have Googled it. https://community.norton.com/en/forums/email-subject-changed-norton-antispamsubject

https://community.norton.com/en/forums/how-remove-norton-antispam-subject-line

Well, yes, I could have Firefoxed it (I don't Google), and likely found the same conversation threads that don't provide any answer that you found.

Not helpful.

Outlook with Norton DOES NOT HAVE THIS PROBLEM. Thunderbird with Norton DOES have this problem.

Same Norton. By what diagnostic paradigm does this qualify as a "Norton" problem?

If you cannot understand that Norton states that their software adds this to the subject line, I cannot help you.

Here are the facts. Thunderbird does not modify subject lines. Norton admits that they do. This is a Thunderbird forum and solving your problems with Norton is outside the scope of this forum.

Next time you want to tell someone they are wrong, do your research so you will not look like a fool.

This could be a fun flame war, but I gave those up decades ago, when I was a kid.

What we have here is multi-vendor environment. I have a great many years experience with that. In a multi-vendor environment, it's virtually certain that every problem not clearly identified to one vendors code, is the fault of another vendor. Very common, never helpful. The interfaces become orphans.

The Norton-Thunderbird interface has this problem. The Norton-Outlook interface, doesn't. This is a problem I experience with Thunderbird, and not with Outlook, having changed nothing in Norton.

So please explain to me, as calmly as possible, why that doesn't qualify as a legitimate Thunderbird question for discussion on a Thunderbird forum? The only people who are likely to have the answer are people who use both Norton and Thunderbird.

I get that you don't know the answer. Why are you so committed to disowning the question?

Thunderbird complies with email standards. It YOUR choice of antivirus that alters the subject line, as Norton admits to doing, Thunderbird displays it. Microsoft makes up their own rules.

For the last time, ask how to work your antivirus in the Norton forum. You have been given the links so it cannot be that hard.

My father taught logic at the University Of Pennsylvania, and my mother established the first technical library for Douglas Aircraft. I had more than enough "Go look it up" to last a lifetime...by the time I was 12!

It's sort of a Golden Rule kind of thing. If someone asks me a question, and I know the answer, I'll give them the answer.

You may rest assured that if/when I find the answer to this problem (the links provided were not the least bit helpful), that I'll post it here.

Who cares! If you cannot figure out that your antivirus software is placing it's name in the subject, not once, but twice, there is no hope. Did you ask in the Norton forum or are you too caught up in your mission to prove me wrong? Good luck with that. I will sit here and wait.

And the REAL solution is:

1) Open your Norton 360 dashboard 2) Open the "settings" tab 3) In the "detailed settings" block, click "anti-virus" 4) Under "real time protection", "SONAR protection", go to "Show SONAR block notifications". 5) Change the setting from "show" to "Log only"

I did a test, and that got rid of the "Norton Anti-spam" additions to my subject lines in Thunderbird. I suspect that changing that setting will work for the Norton "Disarmed" messages as well. Note that I get automatic Norton software updates, so if your Norton isn't current, this may not work. But if your Norton is current, it probably will.

Note that I've never seen that solution documented anywhere. Not here (until now), and not elsewhere. I just poked around, and guessed. I do that a lot.

So, using the same Norton instance on the same computer, why wasn't Outlook doing the same thing? I've been using both Outlook and Norton for decades, and I very dimly recall beating Outlook into submission on the issue, but my memory isn't clear on the subject.

But, for the moment, if it works, it works!

Obviously, you didn't have to wait long. And now, other people with related problems won't need to wait for an actual solution either!

"My Mission"...if you can tell me what that is, I'd be eternally grateful, since I'm still lookin' for it!

I don't know that my solution "proves you wrong", but if you'd like me to do that, I'd be happy to oblige on an issue to be determined!

When I ask for a solution, I'm looking for...well...a solution, not pointers to various links that may or may not be relevant. Perhaps, others have that same perspective when they ask for a solution.

My mission for this specific subject is now complete. I found a solution that works for me, and may well work for many others.

It doesn't get a lot better than that!

So it was a Norton issue. Imagine that. That same process was laid out in the Norton forum postings. Glad you finally read them.
