New European regulations (GDPR) require the use of BCC when emailing a group. This needs to be error proof as the cost of a mistake could be serious. The present system relies on me remembering to select BCC each time I write to the group.

Use BCC instead sounds OK, but I'm reluctant to use an add-in, as updates to TB could make it fail. And if I'm relying on it and suddenly it doesnt work..

Is there some way that I can create an address list so that when I write to that list it will ALWAYS use BCC? The contact data in the address book has about 50 fields, is there no way to set the preferred type of addressing?

I've read other replies to similar questions but none give the confidence in security that I'm seeking.

I have changed the privacy settings as suggested in the help guide, but any image I text to my e-mail is blocked. They can only be double clicked on the footer to open them in another application. Is it possible to have them load automatically in the body of the e-mail?

I found an article how to reset the master password. It worked for Mozila's password in the browser but not with thunderbird. I cannot get it to go to thunderbird's tool to reset it from there.

Currently unable to set up to an existing account on a new laptop. I’ve verified user name and password on the old laptop, but these don’t work when setting up the new one. The Thunderbird set-up wizard found my configuration in the Mozilla ISP DB, but can’t verify it. In other words, it won’t accept my username or password. I’ve done this for both IMAP and POP3, but it makes no difference. I’ve confirmed user name and password for both smtp and mail folders, and tried them in setting up. However, on the new laptop, Thunderbird doesn’t ask for user name, but just the name as displayed to others. Once I get set up, I’d like to copy my archive into the new system. One thing at a time…

After upgrading to Thunderbird 60.2.1, I can no longer send messages. I'm running Linux 4.15.0-38-generic.

I get the attached error saying that I have problems with STARTTLS SMP. However, I have my connection security as SSL/TLS (second attachment). I haven't changed anything for years on my connection security. I successfully sent emails yesterday. Sending still works on my other machine (Windows) with v 59 and the same settings..

I have attached a screenshot of the incoming message from a scam email. It was a request to buy an itunes gift card. Although the name of the sender is mentioned in the subject, the message came from an email address that is not in my contacts. In spite of this, the Correspondents column showed the trusted name, which caused me to respond, although I didn't send money. Can the trusted name be replaced with the actual bogus email address? That would add security.

I'd like to have only email address shown in received mails list.

Reason:

detect forged email is easier.

Things that do not work:

-addons, there is none that works with thunderbird 60 and it should be basic feature

-uncheck in options "show only name for who is inaddress book", done and people are not in address book

-open the email and read the sender there, that's known but is not what i asked

Example:

sender: "Posteo Support <their@mail.here>" but in the list is only "Posteo Support"

mail from friend that changed his name in google account and sent me test email, sender: "Posteo support <friend@google.com>" but again in the list is exactly as the real one: "Posteo Support"

This bypass spf, dkim and maybe also antispam because it's outside their scope

Same apply for s/mime digitally signed emails, there is no column for it, you have to open them one by one to check what is signed and what isn't.

It has been asked so many times in many years

there are multiple, now outdated, plugins for this

Can we have an official answer on why this bacic feature has not been implemented yet in 2018?

also had to type this twice as when i clicked post it said "access denied" and i have lost everything ':/

I had 2 gmail addresses in Thunderdbird. For the first one, I just changed the password authentication method to Oauth2 in the server parameters and it instantly made the replication work.

For the second one, I unfortunately deleted the account and couldn't recreate it, even with the "less secured application" set on in the Google Account parameters. I also tried to activate the 2 level connexion method and generate an application password but couldn't find any way to use it in thunderbird. Therefore, I'm stuck with Webmail Gmail application. I have noticed that the connection has been bllocked by Google (see image)

Hope some body can help (this is related to Google security reenforcement actions but seems that Thunderbird is not up to date on this issue).

Please find attached the first page of my troubleshooting info.

I have not been able to make a connection to the mail.comcast.net for a day now. I see the connecting bar at the bottom but get a failure that it failed to connect. I cleared the password manager. but no popup appears to enter my password in. So without authentication, it cannot get the email. I can't force the login popup to appear to enter the new password.

Server settings are fine, I am using POP3 which is remaining a valid choice. I use avast, current version (autoupdate) Thunderbird is current too. My firewall is WindowsDef, but Thunderbird is on allowed list. I have briefly turned off both Avast and still no connection. I', not sure if defender is blocking even if I selected it. Comcast of course denies anything as the web interface is fine ATM.

(this is not the router or modem as another laptop using thunderbird (probably older as it's my mother's) opens fine. I have done little else for the last day and have run out of things the check, help>! Thanks

Error message says: "The mail server responded: 5.7.57 SMTP; Client was not authenticated to send anonymous emails during MAIL FROM." I see in security settings there's no password entry for outgoing mail on this server, just for incoming. There are separate password entries for incoming and outgoing mail on both my other email accounts. I was not asked for a password at any time during setup and don't see how to add one.

Have removed password entry in security. Tbird then hangs on 'Connected to ....', but does not offer chance to put in new password. So I can see inbox and emails on BT but not through Thunderbird. Solutions appreciated.

I try to connect to pop3.cogeco.ca to download my mail. I get a warning screen that says the security certificate is invalid because it points to another site. When I check into the details, it tells me that the certificate is issued to "pop.cogeco.ca" by GoDaddy.com

According to Cogeco support all my account and server connections are set correctly - and it's Thunderbird's problem>>>>

Multiple people use this pc and Tunderbird. When I open Tunderbird it show the mails I had last time I openend it. I would like it to be hidden until I enter my password so only I can see the emails. Can anyone please help?

When I try to send an email a message pops up saying 'error saving message to sent'. A second message sometime comes. The IMAP server imap.tiscali.co.uk does not seem to support encrypted passwords.. Try changing paswords
