Thunderbird Community Forum

since 8/22/24 I have been unable to send email from one of my personal domains. Same install of T-Bird successfully sends SMTP via Gmail and my other domains.

I receive the error shown in the first photo below. Sending of the message failed. An error occurred while sending mail. Outgoing server (SMTP) error. The server responded: us2.outbound.mailhostbox.com ESMTP not accepting connections.

I have been back and forth with the domain tech support. Here are the email content (parsed for easy reading)

Me > I am having difficulty sending email. > I can POP email without issue. > I am using the most recent version of Thunderbird; version 128.2.0esr (64-bit) > When I send (with or without an attachment) I get the following error: error as shown above > I have never seen this error before and cannot find it in your knowledgebase files. > My SMTP settings: > > server name: smtp.drachenfelspress.com > Port: 587 > Connection security: None > Authentication method: Password; transmitted insecurely > User Name: mcaputo@drachenfelspress.com

Tech: If you are able to download emails from our server but unable to send out emails through the same, then it is likely that your Internet service provider is blocking port 25 on your local network. For such ISPs, you must use their SMTP server to send out mails on their network. Customer Support - TH

WELL Since I was using 587 that didn't help at all.

ME the error says YOUR server, "US2.outbound.mailhostbox.com ESMTP not accepting connections." This is YOUR error, not my ISP. I was using port 587, my ISP does not block port 25.

Tech try non-SSL using the following: STARTTLS Auth Normal change server name to smtp.<yourdomain>.com

Me No change

Tech Try reducing TLS version back to 1.0

Me No difference. Restored TLS 1.3

Tech return to the mailhostbox.com server Port 587 STARTTLS Normal full username

ME ok, no difference. That is where we started, didn't work then, doesn't work now. (second photo)

Tech Try port 25

ME Same results

Tech <resets my password>

Me Did you reset my password overnight?

Tech To investigate the issue, we needed to reset the password for mcaputo@drachenfelspress.com, to enable us to configure the Thunderbird email client on our end. The temporary password is "Se!!P)iqk2" We have successfully created a Thunderbird account and were able to send emails through it without any complications. The configurations we utilized are displayed in the screenshot provided below: us2.outbound.mailhostbox.com Port 587 STARTTLS Normal full username

Then change your password.

Me I appreciate your response. HOWEVER the issue remains.

Tech We have already replied to you on this matter.

ME Tried sending on port 465 and it indicated "sending" but hung there. Using Telnet I am able to access the us2.smtp.mailhostbox.com on port 587 but I cannot trigger an AUTH login through TELNET. (see CMD screenshot below)

Tech What is your IP address?

ME It is not static, but today's is (IP address at the time given)

Tech We have done further testing by setting the ThunderBird email client for mcaputo@drachenfelspress.com to both SSL and Non SSL connections. We can see both the implementations being fetched correctly without any issues. <provides two sets of POP and IMAP settings>

ME I can POP successfully, have always been able to. Problem is with SMTP, outbound mail.

Tech Provides two incomplete setting combinations: us2.smtp.mailboxhost.com port 587 smtp.drachenfelspress.com port 25 Upon using any of the two implementations, SSL or Non SSL as configured above, there should be no issues in setting up the email client.

The SMTP and IMAP passwords (if asked any) will be the same as your current email account password.

We are unable to replicate the issue you mentioned. Customer Support - TH

ME I am unable to replicate your success. I still cannot SEND email.

Tech We have rechecked and can confirm that we are able to setup the email client on the latest version of thunderbird i.e 128.2.1 as well using the same IMAP settings as shared in previous email. We are afraid that we are unable to replicate the issue you are reporting after numerous tests from our end. As a suggestion, could you try to connect to your mail account from a different network or ISP? Customer Support - TH

ME Again, IMAP is not used on this account the issue is with OUTGOING mail. Tried both SSL and non-SSL settings for drachenfelspress.com outgoing mail will not send.

That's ALL I have right now. I am going out right now to try to send email from a laptop with a fresh t-bird install while sitting in a McDonalds on their wifi...

Help?

Canon Scanner issue with Thunderbird using MP network EX 2.0, I have 4 win 10 systems all using LiDe200 and 210 scanners with similar problems, 2 systems I can attach emails to Thunderbird only manually now as the Thinderbird email client isnt shown on the dropdown box only (None attach manually) and the other 2 systems cant send anything at all, comes up with the above and the with a message saying no program is accociated with it, even though Thunderbird is the default email client ............when I try to attached it to an email ............... I have NO IDEA how to fix this and I'm not technically very good either so need answers I can understand and do with out technical jargon I dont understand, I did ask a computer guy who does our systems but he didnt know what the problem was and had no solution for that. I am hoping you can help with it as I'm super frustrated with it, as it came on the back of another Thinderbird issue I have with security exceptions which defies being fixed. HELLLP !

Hi, Please see screenshot. The "From" field does not have my address and there is nothing to select in the drop down. I cannot type into the body of the email either. Also, when I click on "About Thunderbird" I do not get a pop-up window with version. I am receiving email. Thank you Cams

Hi

I recently updated to 128.2.1 esr and my message filters are not working. When I open "Tools" > "Message Filters" the filter list is empty but when I open the msgFilterRules.dat file on my profile the message filters are there. (I made lot's of them.)

Hi. Is there a way to add travel time to an appointment just like you can do in google or apple calendar? It’s a great feature. When I add an adres to my appointment Apple calendar will automatically add the travel time by car from my home to the destination. I miss that feature in Thunderbird.

When I switched my computer on this morning, Thunderbird refused to dowload new emails. Nothing I have tried solves the problem. A message in Crash Reports says:

"Shutdown hanging at step XPCOMShutdownThreads. Something is blocking the main-thread".

My copy of Thunderbird is up-to-date and accesses two accounts (Gmail and my university account (IMAP)). New emails are missing from both.

Any advice on how to solve this problem would be appreciated.

Thank you,

Hi Thunderbird Support Team,

I recently installed the latest version of Thunderbird in a Hyper-V virtual machine and encountered the following message: " Approval required Mozilla Thunderbird This app requires your admin's approval to: Read and write access to mailboxes via IMAP. Read and write access to mailboxes via POP.

Allows the app to have the same access to mailboxes as the signed-in user via POP protocol.

This is a permission requested to access your data in xx Send emails from mailboxes using SMTP AUTH. Maintain access to data you have given it access to View users' basic profile"

This was functioning with the previous version of Thunderbird, but now my IT team requires additional information about what the app is trying to do with our Office 365 environment. The approval process is crucial because some apps may introduce security risks or seek extensive access to our Office 365 resources.

Could you please provide more detailed information on the permissions requested and the specific changes in this version compared to previous versions? This will help in getting the necessary approval from our IT team.

Thank you for your assistance.

Best regards, Jenny

Our email accounts are attached to our host domain name. We are going to be changing the host domain location from a smaller local provider to Spectrum Internet to service. The email addresses XXX@xxx.com 'will not change, only the server host location. As a backup, we are moving all existing emails located in subfolders under the email accounts to the LOCAL folder (creating new "trees" there) so they are in a permanent location to be unaffected by the server change. From my knowledge... we will not create new email accounts in Thunderbird .... only change the server location, ports, etc for that specific email. I want to confirm with others that this should be the plan?

Thanks for listening: Last week, Thunderbird began returning this message with each attempt to send mail: An error occurred while sending mail. The mail server responded: <tedcomo@chartertn.net> sender rejected. Please verify that your email address is correct in your account settings and try again. I have no problem receiving mail. At the same time, my wife began having the same problem on her laptop, which tells me either Charter, or Mozilla, changed something. I started with Charter. They told me to rename both servers to mobile.charter.net (outgoing mail was formerly smpt.charter.net. No effect. They then had me log into Spectrum and send a test mail directly from my account. It went through OK and they said the problem had to be on Mozilla's end. Any suggestions?

The global search in TB is completely defective. I am now running 128.2.0esr and hoped that update might fix it. It hasn't. I just wonder, are there any older or non ESR versions I can downgrade/move to, where the search is fully functional?

In Thunderbird calendar, on 27th Oct 2024, entries added are displayed one hour ahead of where they should be. If the entry is edited, the times are correct, and they show correctly in another calendar app (Calendar on my iPhone). The issue does not occur for events on the day before or the day after, and is the same for a newly added event as for an existing one.

See screen shots. You can see my test event displayed at 11:00 - 12:00 but on editing it is actually 10:00 - 11:00 - the latter is correct.

27th Oct is the day that DST ends in the UK (at 0200) in 2024, but the events are several hours after that.

SOME EMAILS CAN BE MOVED TO FOLDERS. LARGE NUMBER OF EMAILS SOMETIMES CAN BE MOVED TO FOLDERS. THEN, ALL EMAILS MAGICALLY APPEAR AGAIN. WHAT GIVES? IS THERE A SPECIFIC SETTING THAT IS CAUSING THIS GEM?

My e-mailadrees is alois.hufkens@skynet.be I get continously the message , I translate because the message is in Dutch, "Enter your password for fd045290 on pop.skynet.be". Can anybody help me? My phone is [edited phone# from public community support forum]

Using TB 115.15. When I delete a number of messages, then empty the trash, I cannot delete another message until I restart Thunderbird. Is there a limit as to the number of emails I can trash prior to emptying the trash?

G'day from 'Straya!

I have migrated Thunderbird from one Windows laptop to another, copying the profile and all included files. This mostly worked but has created a couple of issues I am trying to troubleshoot and could really use some help.

First thing probably worth noting is that I had an earlier version of Thunderbird on the old laptop than the new one downloaded to the new laptop. I don't that if that is the problem.

I have two email accounts which are both using IMAP. When I delete an email in Thunderbird, it keeps coming back and I now have multiple copies of that email. My storage is filling up 😒 Is there a setting I am missing?

Additionally, the migration does not seem to have brought over my contacts. Did I miss something?

Any help and advice will be greatly appreciated.
