Thunderbird Community Forum

My business has two domains. I can send email to a Gmail account holder using the primary domain with no issues. But amy emails from what I call the "secondary" domain below are treated as spam. This occurs with two different email addresses using the secondary domain.

Both domains are hosted with Bluehost. Exhaustive research has revealed the following:

• Settings in Thunderbird are exactly the same, e.g. ports, security, SSL/TLS, etc. for each domain.
• There is no subject line or content that could possibly be regarded as spam.
• MXToolbox indicates that the secondary domain is not on any blacklist.
• Extended support via Bluehost reveals that SPF, DKIM, and DMARC records are all correct.
• Email sent to a Gmail account using the CPanel (Roundcube) is not flagged as spam. Only emails sent via Thunderbird are flagged.
• Emails sent to a Gmail account from the secondary domain using my mobile phone, but still on the same network/IP address, are not flagged as spam.
• If I first send an email to one of the secondary domain emails FROM Gmail, then reply to it, the reply is not flagged as spam.

After many hours of head scratching (and later, head banging), I am pretty much at my wit's end with this problem. I'm an electronic engineer but this one is definitely out of my wheelhouse. Any help would most certainly be appreciated!

Thanks in advance, Don

Suddenly two days ago all my emails began going to Spam when the download. I know of no changes to my system or Thunderbird. I deleted everything in my Spam folder and reset training, but that didn't help.

Does anyone have any ideas?

Cheers, John

My Charter.net mail has suddenly started to come into my inbox and automatically is moved to trash by Thunderbird. I do not have antivirus, i have not changed any settings, it is POP.

Since some time late last night (so about 16 hours ago at most), my Thunderbird account started processing filters incorrectly on incoming emails. A number of legitimate emails were detected by filters I had set up, and deleted, although they did not appear to meet any of the criteria I put in the filter. On editing the filters, I did find some with a criteria active on the 'from' address, containing, and with a complete blank in the text box. I am not sure if this meant they were picked up by the rule, but I deleted all lines with blanks in them. Following this, some emails were still being processed as meeting the criteria of the rules, although they did not. It does now appear to have settled down, but instead, messages that I personally deleted, are not appearing in the 'deleted emails' folder until after I close down Thunderbird and re-open it again. (which is a little confusing, but I am coping). At this point I do not need any assistance, so long as this strange behaviour stops happening, but I was trying to work out if it was something in my Thunderbird programme awry, or something at the mail server, and I have not been able to confirm either, so thought I ought to let you know. I usually install Thunderbird and Firefox updates as soon as they are available when the programme notifies one is available. I do like the appearance and function of Thunderbird, and appreciate what you do - Thankyou. Best wishes, David Church

I've recently started having an issue where emails sent from my email account are being delivered, but some of them are ending up in the recipient's spam folder.

I'm using Thunderbird and the account itself appears to be working normally. I can send and receive messages without seeing any obvious errors.

I've already checked the SMTP settings, but I'm wondering if this could be related to my domain's email authentication rather than Thunderbird itself.

What should I check for SPF, DKIM, and DMARC, and is there a good way to determine whether the problem is with Thunderbird, the mail server, or the domain's email configuration?

Using version 154.0, all of my incming emails are going into my spam folder and my inbox is completely empty. I have turned off the spam assassin filter and the adaptive spam filter, but the problem persists. If I move a message from the spam folder to the inbox, it goes back to the spam folder within 3 seconds. I know that this is a Thunderbird issue because I uninstalled it and used my browser to access my email from my provider (runbox.com) and my inbox functioned correctly then. After I reinstalled Thunderbird, it somehow retained all of my settings and the problem persists. Is there a way to fix this?

I'm getting Spam Emails from about 10 regular Spam Accounts and I wish to Universally Block them by adding Them to my Filtering Lists. I'm using the * Character as a Universal Place Holder for the *@*.com, *@blah.blah.ca or com. The Filter works one Time then stops working for any fresh Spam. In other words, the Filter doesn't Filter any new Spam from these Addresses. Why?

========================================

A few days ago the left (file) pane went from

- InBox
- Drafts
- Sent
- Junk
- Spam
- Trash

to

- InBox
- Drafts
- Sent
- Spam
- Spam
- Trash

I attempted to change the first "Spam" back to the original "Junk"; didn't work. Have no clue why TBird decided to change the file names on its own.

Any information/direction(s) about how to correct this back to the original?

Thank you / appreciated. Nels

I recently added a email address to my thunderbird email and it brought forward a lot of messages from Yahoo that are spam. I would like to block them and instructions I have were dated 2016 from Mozilla. Is there a new instruction on how to block?

In previous versions of Firefox it was easy to create a filter. Not anymore. I want to allow trusted addresses to come into my Inbox without going into Spam. Even when I follow (Google's AI) instructions exactly, all my medical information goes to Spam AND the trusted filter I created seems to have blocked dozens of browser choices in DIY sites, among others.

Over the last week or so, I have received an enormous amount of scam, but no matter how many times I "train" the filter, it doesn't work.

I have just received another 3 from this site: mid:02guhjkj6-ABMcSHN6Or-JiC-000000@eu-central-1.amazonses.com, which claim to be from Madasafish Security>security@qi9adgongzenElptrum.de

I have tried on several occasions to follow the manual instructions how to deal with the spam, but I find it so log-winded that my non-techie brain, which is not wired for these kind of things, gets tired and I give up. If anyone has a more intuitive approach how to deal with this, I would be very appreciative. I have marked sites multiple times as spam, but the spam control ignores me!

I have a particular need to periodically run junk mail filters on a folder in Local Folders that I know will contain mostly junk mail. According to a search engine, the command to do filtering on particular folders should come up in a junk mail tab when you right click on a folder and look under properties. When I right click on a folder, however, I never see a junk mail tab under properties or anywhere else. Where to I find the command to do junk mail filtering on a specific folder? Greatly appreciate any assistance.

I have forwarded (from my Thunderbird account) an email from our local hospital about an appointment to my mailfence address three times now, but all three were deemed undeliverable by the mailer-Daemon. I removed all links on the third attempt in case that was the problem, but no luck.

Error code: 554 Rejected : Spam ?

For further assistance, please send mail to postmaster.

How do I do that? Is my question. Is there a 'Postmaster' address to use?

Many thanks David Edwards
