I always use Mozilla Thunderbird for email. Today, it would not send outgoing email. Any email gives me a failed message: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Spam detected by content scanner. Message rejected (ID 665754780026FB52). Please check the message and try again."

My ISP insists the problem is not with their server, and I need to have Mozilla correct it.

I use firefox (as mozilla) for decades ago. Never had issues, is super easy, fast and ...secure (?) A hacker last week have access on my Firefox, download ALL my saved passwords as CSV... as a plain TEXT and ATTACKS on my entire life!!! And the nightmare goes on and on... Stole my primary Google Account, Facebook, Instagram, Ubisoft, PayPal, Microsoft Account.... and other 20 sites beside this. For GOD sake, didn't you EVER think to place an extra security layer on this EXTREMELY SENSITIVE details??? A master password? 2FA or something else? Are you serious??? I'm so sorry BUT YOU'RE LOST MY TRUST!!!! Period!!! Give a change to your selves and PROTECT YOUR CUSTOMERS!

I have an issue trying to configure a secondary email account, for a non-profit I do some work for. It was ok in the past, though I recall was tricky to set up on TB a couple of years ago. But now it has ceased to function after I migrated TB profile (successfully apart from this issue) no matter what I try. I’d be grateful for any suggestions. As is the case with many non-profits, there’s little tech support, but others can use the email account ok. I think it may be a TB issue as I have been able to set up the account ok with MS new Windows Outlook app (lame, but better than Mail…low bar). I’d rather have this account on my TB client along with the others I use. And the issue is replicated on two of my PCs. TB account set up reports “can’t detect settings from host server”. I found a support thread link text, which says “The failure to detect settings is rather common where hosted domains are concerned. Mostly because everything is done to a price and most of the things around encryption are done in a halfhearted manner. As is the server setups for mail. However by faithfully copying the settings from the provider as to domains server name and ports it should work.” So I did manual configuration – copied the settings from the successful Outlook set up, but no dice – all I get is server time out message. Settings are: IMAP server: mail.XXXX.org.uk Port 993 Security SSL/TLS [earlier working settings were STARTTLS port 143] SMTP server: mail.XXXX.org.uk Port 465 Security SSL/TLS [[earlier working settings were STARTTLS port 587] And using Normal Password for both; I tried Autodetect too but no good. I’ve see a suggestion that turning off the firewall (Norton) might work, but I’m reluctant to do that and doesn’t seem to make sense that would cause the issue. I found another suggestion that apparently works for some people - leaving password blank on setup. https://support.mozilla.org/en-US/questions/1399690. Before I try, are there any other suggestions or ideas? Trivial matter in the long run, but bugging me. Thanks

Hi,

I am facing an issue with Thunderbird.

I integrated my email address but there problem is the new message is giving "Undelivered Mail Returned to Sender" but I can reply and receive the emails.

Please guide me about it.

Many Thanks

One of my two gmail accouns has suddenly become impossible to access (cannot receive, cannot send). T'Bird produces an Authentication has Failed notification, after a Google Window headed "Sign in to Mozilla Thunderbird Email" which refuses to go away. Clicking on the 'help' or 'privacy' options in that google window produces no more than a blank window but then "Sign in to Mozilla Thunderbird Email" reappears a few minutes later. My other gmail account doesn't have this problem, so I assume it's not gmail but it's T'Bird.

What's going on?

(BTW signing into this Support resulted in an email "New sign-in to Mozilla Support" warning "New sign-in to Mozilla Support to Firefox on Windows 10". Trouble is, I'm on Windows 11. Trivial maybe, but telling maybe.)

Help me stop the DNS log flood with connection requests to

push.services.mozilla.com

which are blocked.

dom.push.connection.enabled = false dom.push.enabled = false

Seems a tad deceptive. UI settings for notifications has none allowed and new requests blocked.

On a related note I would like instructions to have the browser cease attempted conversations with these resources

firefox.settings.services.mozilla.com shavar.services.mozilla.com content-signature-2.cdn.mozilla.net aus5.mozilla.org

All experiments disabled yet normandy.cdn.mozilla.net

If mozilla respects privacy why are not experiments opt-IN?

Thank you for your kind help

Hello,

My protonpass manager and email accounts were compromised by a hacked Discord user. I began setting up the password manager in mozilla to help me with my passwords, but somehow mistyped the Master Password I was trying to set up. Now I have no idea what it is and need to reset it.

Thank you,
