Thunderbird Support Forum

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

I keep getting this message sporadically: "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.hughes.net failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again."

I sent messages yesterday with no problem!

I can't see any issue with the SMTP settings. I've tried troubleshooting mode.

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!
