My email seems to be blocked, I don't have mobile.charter.net Message says it doesn't come from a trusted source.. I've used [edited email from public] @charter.net for over 5 years with no problem.

I set up a filter to move messages to the junk folder. If it's not from a .com, .net, or .org domain, move it. Here's how I set it up... If the "from" incoming message doesn't contain "any of the following" ".com" ".org" or ".net" move it to "junk". It moved .com and .org messages to junk anyway. What did I do wrong? There are too many TLDs to create a filter for all of them.

Hi I am Unable to send e-mails (only receive) after adding a 3rd account to my thunderbird, a microsoft e-mail (the other 2 are gmx and my old work e-mail). This is my private laptop. I tried tons of troubleshootings incl. deleting passwords, triple checking all settings (they are all correct), but I always get a pop up with "Login to server smtp.office365.com with username ... failed" when trying to send an e-mail. When I click on enter new password it just tries to send the e-mail again, which fails, so unable to enter anything.

I accidentally deleted a good number of my emails from my local Pop3 server account. I don't delete my emails from my gmail server so I can just redownload all my emails but cannot remember the prefix needed to do it.

If I recall correctly I go under settings for my email account, then go to server settings and add the prefix to my email shown in the Username field under the Pop Mail Server Section.

Can anyone remind me of the prefix?

It was like restore:[my email] or all:[my email].

I should have made a note of it as I cannot find it anywhere online now.

I have a desktop that is windows 10. I use Mozilla for four email accounts, 3 of my accounts work fine. My problem is with TWC. Emails sent/forward and cant save drafts often fail. When I sign into spectrum webmail, my Mozilla TWC account works again for a while. This started about 2 weeks ago. I'm using version firefox version 151.0.2. I've eliminated Spectrum as being the issue and all my settings are correct. Thoughts?

I keep getting the following error when trying to download emails from yahoo.mail: Authentication failure while connecting to server pop.mail.yahoo.com Have hundreds of emails sitting in yahoo.mail that I need to load onto my desktop. Any help is appreciated!

This just all the sudden started happening for my charter email account, I haven't changed any settings, the font turned red and can't receive the emails. I have mail washer and see the emails, they not from anyone shady. got a couple screen shots. Thanks

I have numerous Ionos email addresses. No problem seeing all received emails in Thunderbird app on my Windows PC. But Android app does not show some emails, despite synchronising numerous times. Problem is often with emails not showing in the unified inbox on the Android app. Also a problem with sent emails not showing. Today I looked for an email I had sent four days ago, and it was not in my Android sent folder. Synchronised, still not there. Synchronised again, still not there. Went online to Ionos and opened the sent email. Synchronised Android Thunderbird again and then it appeared. Why can't Anroid Thunderbird see certain emails? Problem seems to be especially bad with emails I have previously opened in Thunderbird on my Windows PC. Doing so seems to make the emails invisible to Android Thunderbird.

I received a spam message this morning that had a "Disposition-Notification-To" (aka Read Receipt) line that had MY email address on it. I honestly don't know why a spammer would do this - but that's not the issue. I have Read Receipts disabled, but Thunderbird generated an email (to me) and sent it to my mail host. This seems like a bug. Even if the Read Receipt has my email address on it (making it mostly harmless), Thunderbird shouldn't have generated the message. Or am I missing something? Thanks.

After using Thunderbird for many years, suddenly when I try to send an email, I get the error message "daily user sending limit exceeded". Apparently, I was the victim of a phishing hack yesterday, where a fictious email was send to everyone on my contact list. I have not been able to notify anyone because I can't send emails.

When I try to send an email, I get the following response. Sending of the message failed. An error occurred while sending mail. The mail server responded: invalid user ID or password. Please verify that your email address is correct in your account settings and try again. Have looked in account settings and cannot see a password anywhere. Email address is correct Help please Carol

Today when I started Thunderbird two of my email accounts are Highlighted in RED with a RED Triangle at the end of the email address.

Both accounts are from Spectrum. My other email accounts from another provider are OKAY.

I am not able to retrieve or send emails on these two accounts. I can get my emails from both accounts when I use Spectrum Webmail. So it looks like the account information is correct.

How do I fix this?

I've been using Thunderbird on Windows 10 since last year sometime. Currently I'm on version 151.0.1.

I've 4 x mailboxes here and since yesterday, 3 of them show me an unusual message when checking for emails. I tried attaching a screenshot but although the screenshot uploaded, I couldn't find a way to insert it here. But the message says Unable to write the email to the mailbox and asks me to check if I've write privileges (which I have) and to cheek the available disk space.(currently 101GB free).

The message is happening 2 or 3 times each day and lasts for about half an hour, then everything works fine again. Has anyone else seen this??

Can't download messages on one of my computers. Account icons show locked, I think. See attached file. Downloads were working but now can't download anything newer than 01 June. How can I "unlock" the accounts? All my other computers are downloading messages just fine.

I've been a Thunderbird user for years without problem. However, since May 22, three specific messages continually reappear after deleting them from my Inbox.

I keep my Inbox empty and it stays that way, except for these 3 messages. Removing them from the Trash folder has not solved the problem.

My email provider is netaddress.com via POP3 account. I signed on to look at my inbox on their site via a browser, and the messages aren't there.

I have tried repairing and compacting the inbox, but the messages continue t reappear.

Do you have any other suggestions?

TIA.

Hello,

Everything working just fine last night. Wake up and Thunderbird will not retrieve emails.

Remembered this old message I got so I went through and deleted my second email address, didn't help.

https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo

Checked all settings compared to Yahoo, still won't download messages. I can even send a message with my current settings no problem, and it does login, just won't retrieve emails. Gives me a connection timeout.

Anyone have any ideas?
