Comcast/Xfinity is binning email sent from Thunderbird to yahoo, gmail or hotmail

This problem started on April 24.

I have compared the Mozilla info at the front of emails sent to my wife before and after April 24. The only differences other than Subject and content are:

    From - Mon, 22 Apr 2024 16:34:28 GMT
    From - Sat, 27 Apr 2024 08:10:47 GMT

    Message-ID: <c43e9437-1603-41fe-bc73-699c2ac4ddb0@acm.org>
    Message-ID: <ce6cfda0-24b8-4503-9838-2d16fe8fbe94@acm.org>

- The Message-IDs are identified as @acm.org - My sending address with Thunderbird is @acm.org - My ISP for Thunderbird is @comcast.net - If I send from xfinity.com which is comcast, the emails succeed - If I send from Thunderbird, the emails fail as follows

Emails to yahoo get:

Diagnostic-Code: smtp; 554 5.7.9 Message not accepted for policy reasons. See https://senders.yahooinc.com/error-codes

Emails to gmail get:

Been using Thunderbird for 5 or 6 years now and am a big fan. However, in the last few versions, the tool seems to be more and more resistant to actually checking for mail when told to do so.

It frequently does not check at startup ("Check for new messages at startup" is checked for all accounts), and also does not check when "Get all new messages" is selected.

I have tested this with known mail waiting to be retrieved and Thunderbird does not do it when directed. It did eventually do it, and downloaded the mail, but I am not sure why the reluctance to check on demand by the user.

It is possible it may just not be REPORTING that it is checking, but failing to get mail I know was there kind of makes that less likely.

The earlier versions, from 5 years ago, worked very well in this regard... always checked on startup and when told to, always reported the activity in real time as the check proceeded. The newer versions are not good at this. Or it is user error, which is definitely possible, but I'm not sure what I might be doing wrong.

Currently using Thunderbird V115.10.1 64 bit, running on Linux Mint MATE. This is the newest version available as of Apr 29, 2024, and the problem seems to be worse in this one than in the previous version. Not positive on that, but I did have a dickens of a time getting mail downloaded that I knew was there.

Any input or ideas will be most appreciated, thank you in advance.

Can't print emails or any saved Thunderbird files. I click on FILE>PRINT and get the print preview, butwhen I click on "PRINT" I get a "printer offline message". I can print from Microsoft Word or PDF files and any other program. It appears that everything worked well until the latest Windows update was installed.

I am using an HP printer and print via HP's Smart Print software which I believe is the default. I'm not sure if this is a Thunderbird issue or another screw up by Microsoft.

Thanks for your assistance.

I am the beneficiary (or victim, depending on how you view it) of Cox Communications turning all email services over to Yahoo. Both Cox & Yahoo store messages on an IMAP server.

As seems to be Yahoo's custom, they provided minimal documentation. Last night, in a 3+ hr call to tech support, for example, I noticed that my inbox had exactly 10,000 messages. (I know. It's not Inbox Zero -- I'm a bad, bad boy.) This seems suspicious, so I asked Yahoo's tech support agent about it. At first they said Yahoo puts no limits on messages and blamed Thunderbird for this. Then I showed them my employer's Gmail inbox with 35K messages and said this proves it's not Thunderbird. Then the agent said Yahoo has no limit. Then, apparently after getting feedback from their "support team," they said there's a limit of 10,000 messages per folder. So, even Yahoo's tech "support" seems almost clueless about such undocumented "features."

I know I need to trim the inbox, but I also need to keep lots of messages currently in it. So, the first thing I have to do is to move a large number of messages from the Inbox to another folder whose contents will be fixed.

To do this, I first created a folder to keep the original messages, "Cox Inbox."

Then I created a message filter with the following logic:

• Match all of the following: Date, is before, 4/7/24 (the day before Cox migrated my account)
• Move message to, Cox Inbox

But despite trying this repeatedly (I also tried "Match any of the following"), most messages stay in the Inbox and relatively few make it to the "Cox Inbox." I don't know how to troubleshoot this. Can you help?

Not being able to get the filter to work, I tried brute force. In my Inbox, I highlighted all the messages I wanted to move, pressed CMD-C (I'm using a Mac), went to the Cox Inbox, and pressed CMD-V. But it seemed nothing happened. Again, I'm at a loss as to how to troubleshoot this. Please help.

Since this morning 99% of my tasks disappeared. When trying to reset the lost tasks I remember by converting emails to task or by entering them as new tasks from the taskbar, they do not save and do not show up.

I restarted thunderbird a few times. Whilst doing that there was an update. I think windows. Thunderbird tasks still not working. Checked updates and Thunderbird is up to date.

Converting emails to tasks is extremely important to me.

Starting yesterday firefox, no recent updates etc, gives a 403 error for several large corporate sites and 404 page not found for most paypal payment pages. These sites/pages work fine with Chrome. There were no changes by by myself to my firefox installation, not any antivirus changes.

Within the last hour today everything is working properly. What is going on? jn

Whenever I open TB (115.10.1) new messages download. The problem is the newest message topic is in the Inbox list but it is hidden behind the column headings. I have to scroll the list down one message to see the newest message. Why is this?

Hi, I'm having issues with my Google search results page. It used to be very clean looking and mainly only showing the results of whatever I searched. Today though, I searched something and now the Google results are first showing Reddit answers, what others have asked, discussions and forums, what others have searched, short videos, etc. I have to scroll really far down just to get some normal search results. How can I fix this? Call me old school but I want the classic version back. Please help, I don't want to switch browsers. I've been using Firefox nearly since it's launch, since StumbleUpon days. Yeah!!! If you know, you know. Thanks!

I have 4 different email accounts, all managed by IONOS. These have all been set up under thunderbird OK. But when I send an email from 1 of these email accounts I always have to enter my password for that a/c. With all the other accounts, this is not necessary. I do not use Thunderbird or Firefox password managers. I assume that I must have made an error in setting up the outgoing details when setting up that particular account in Thunderbird, but I cannot find a way of checking if that is the case.

After updating Thunderbird to 115.5.2 I receive an error when I check (get) messages of my gmail account : 'The STAT command did not succeed. Error getting message number and size......'. However, the messages do come in and so the error turns out false. since the authorization (OAUTH2) credentials are accepted.

I have my server settings check messages from startup; every 5min; automatically download new messages. That works fine. Again only when I goto "Get Messages" the error shows up.

What is wrong here and ho do I fix this? Thank you
