Do you have an ant virus with spam stuff. Trend used to mess everything up, I assume the others are equally capable of being defective.

Got a spam filter on the server, perhaps your mail provider is being helpful.

No, I don't have any antivirus software on either the Linux machines OR the Windows machine.

Is there any where I can just completely REMOVE the Junk options? I really have a good spam filter on my email server and don't need it at all.

Tools menu > Account settings > select the junk settings for the account and deselect the enable junk mail controls for this account.

Anything else will be you really good spam filter not being really good.

Yes, as mentioned above I've already disabled the filter on all accounts AND in the global settings AND I've attempted to change prefs.js.

Guess it is time to change to a different email client...Thanks anyway.

Yes, kmail is good. It will probably have the same issue as you appear fixated on the mail client.

You have turned off junk filtering in Thunderbird but persist in the incorrect view that the mail client is doing this. Turn off your server side spam filter and see if it is the cause. Thunderbird is unequivocally not the issue here.

Our email server does not have this type of spam capability. I work for the ISP and am part of the email server admin team. This is a client issue as this does not happen with any other email client used. And Thunderbird incorrectly marks things as Junk even though all Junk settings are turned off. It should not do that. If the settings are off, there simply should not be a marking of junk by the email client. This is unequivocally a Thunderbird issue.

What are the steps to reproduce then? Including the email server software. I have never heard of such an issue until now that is not directly attributable to either the ISP spam software or the anti virus so exactly what is causing it needs to be determined. To do so someone is going to have to exactly duplicate the environment.

Can it be reproduced connecting to another mail server not maintained by this ISP? Does the ISP software loose the plot when there are no email addresses in the online email address book? Some certainly do.

Most importantly of all. Is there a spam entry in the header? Please post a sample message header. Is there any mention of the message being spam other than it's presence in the junk folder

Steps to reproduce: 1) Get email (all email is marked as Junk)

I've blown away profiles and re-setup the entire accounts. I've got accounts on different servers and types including the one producing the header below and a Microsoft Exchange Server 2010.

Header --END

I can see no spam header in this. Also, Thunderbird has been working for years prior to 31.4. And again...It wouldn't be a big deal except that I've told it to TURN OFF JUNK SCANNING COMPLETELY. It shouldn't matter if the dang message had spam headers or not. If Junk scanning is turned off, Thunderbird SHOULD NOT MARK IT AS JUNK.

That is not the header from Thunderbird.

Now. I got a mail and it was not junk so there has to be more to the steps to reproduce the issue.

Try this simple test. Add the address from these replies to your address book. Create a test reply on the thread. If it is marked as spam turn on the junk controls and repeat. Is it still marked as spam?
