Thunderbird-Hilfeforum

I'm at a loss, and I'm being bounced around by a ping pong by Comcast and Optimum. Let me state some facts. 1. The error I'm reporting here, I have NEVER EVER seen before. 2. I have 2 email comcast email addresses, they have worked with Thunderbird for over 15 years- no issues. 3. Optimum is my ISP for the past 5 yrs- no issues like this. I don't have an email address w/them. Seems they don't provide them anymore I was told by their rep!

Earlier last week I noticed I was not receiving emails at all from on my iPhone. I use the iPhone Mail application for email.

I opened Tbird this morning and saw this WEIRD message for both comcast email addresses.

Sending of password for user xxx@comcast.net did not succeed. Mail server mail.comcast.net responded: [AUTH] Temporarily blacklisted IP Address - try again later

Then the following window in Tbird appears both accounts each.

Login to server mail.comcast.net with username xxx@comcast.net failed Retry, Enter New Password, Cancel

No idea what the above blacklist error means.

I called Comcast. We checked/reset the passwords on the accounts in the comcast webmail, I changed them in Thunderbird. I checked both inboxes, and there were over 40 emails I never received in Tbird, nor on my phone, inside Comast's webmail.

Using comcast webmail on my PC, I am able to send emails to myself from both accounts, and reply. My friends are able to send me emails to both accounts. However I can only see the emails on my phone, NOT in Thunderbird.

Here's the more weird part.

My primary comcast (#1) email address on my phone works ONLY when I'm using my cellular data. If I connect to my ISPs router, I cannot send/receive email at all from comcast, and using Apple's mail app, I cannot send email using the gmail account that I have in Mail also. The gmail is independent from comcast.

If I disconnect from Optimum WiFi router, then the following works: 1. Gmail- can send/receive email 2. Comcast email #1 (Primary)- can send and receive emails from/to anyone 3. Comcast email #2- can only receive email, it cannot send at all.

When connected to my WiFi both comcasts read same error in Mail app with "Cannot Get Mail, xxx is currently unavailable"

And no matter what I do- Thunderbird continues to give me the above error and nothing can be sent OR received in Thunderbird.

I have no idea where to go on this one.

Thanks in advance.

Hi, I downloaded messages from an university account to a local folder created in Thunderbird. After doing so, I deleted the online messages to make room for more messages, since the university account has very limited space. However, the donwnloaded messages are only visible in preview mode, with a short truncated text. If I click on them it shows a blank message, and attachements are missing too. I already did this before and it worked well. Any idea what was wrong this time? Is there still any way to fix those messages (they are not available online anymore)? Thanks!

When writing an email message, periodically the cursor jumps to the subject line.

A prior thread recommended unchecking the hardware acceleration option at Settings / General / Indexing -- though that has not worked for me.

Does anyone have a solution?

Please provide guidance on how to fix this issue. When I attempt to transmit an email I get the error: "Add security exception, Location: smtp.aol.com:465 This site attempts to identify itself with invalid information." When I Confirm Security Exception I get: "Send Message Error: Sending of the message failed. Peer Certificate issuer is not recognized. The configuration related to smtp.aol.com must be corrected." I cannot receive any emails either. No error message just no new emails since 5/29/2024. I have verified the settings needed and checked my system that they are correct. As this happened after an update I think this is your bug.

Two related problems I think:

1) I have never used the Archive facility, and I've unchecked the box in the Copies & Folders | Message Archives | Keep message archives in - for all the mailboxes. But I'm still getting *some* messages appearing in the Archives mailbox that now has no subfolders. And I never type "A" when reading a message. Some messages just appear there. They are duplicated in the Unified Folders.

2) On a random basis (every couple of days) the Archives folder gets several blank messages the date of 12/31/1969 that I can't delete or read. They can't be marked as read either so they stay in bold. And a little while later they're gone.

I am running Total Defense as an anti-malware, and I saw elsewhere the suggestion to turn off scan of the mailboxes, but wouldn't that leave me vulnerable to malware that comes in via emails?

Any idea what's going on? TIA!

Hi, I know 95% likely NOT to be Thunderbird but hoped someone might have some advise.

With TSOHost & they recently migrated me to xxxxxxxxxxxx.prod.sxb1.secureserver.net (no choice) I think this is a GoDaddy server.

emails use to Go instantly (talking about the delay between pressing send & it going, so I can go on to the next. Not how long it takes to get to the received. Now 4 to 10 seconds, I guess 6 or 7 seconds on average. Short emails, no attachments, size seems to make no difference.

SSL & ports etc. all seem fine, it works, just slow. Not changed anything else in TB apart from the server name.

Is faster direct from webmail but prob. around 4 seconds.

Thankfully receiving is just as fast as before, again the update of what is shown, not from X to Y. TSOHost once moved me in error & I had similar slow but also on receive, might open TB & it was 10 - 20 seconds, I think even longer, before incoming were show & updated. I got them to move me back. I think then it was GoDaddy underneath. TSOHost say its down to the client, which seems unlikely if the day before migration it was OK.

Any advise/ideas. May not seem a lot but doing through lots of short emails, it does slow you down.

Can't see how virus detection could be involved, as nothing changed, perhaps a difference server, Windows defender is doing some more stuff, wild guess?

I use Thunderbird to check the 15 different email accounts that I have to respond to. On the 4th of June it just quit sending or receiving emails. I tried deleting some of my emails but it hasn't helped. Do you think I haven't deleted enough or would there be another reason for it to quit working.

I just marked an email as spam/junk and I expected it to be moved to the spam folder. Unfortunately this did not happen. Even after restarting (latest version)Thunderbird the spam mail is still in my inbox. It's a bit disappointing and unexpected. Am I doing something wrong, or does this kind of functionality depend on the imap server?

If I try to save an attachment or add an attachment Thunderbird flashes up a window for one second then crashes. It only started happening a couple of days ago.

Tried attachment extractor add on but same issue. In "Settings > Save files to >Browse" also crashes. crashes also in troubleshoot mode. latest version of Thunderbird.

last crash report : Crash ID: 6c97ce14-2f2f-4f09-9424-6c7780240608
