I have changed absolutely nothing on my computer and this has just happened out of the blue. The following message appears whenever I attempt to send an email:- Sending of the message failed. An error occurred while sending mail. The mail server responded: 626F290E04D8BA88 Message content rejected due to suspected spam. OB703. Please check the message and try again.

I backed up the thunderbird profile as per video instructions to external drive. On the new pc I installed thunderbird and copied to the roaming folder the filed previously copied from old pc. After doing it and opening the thunderbird, it doesn't open as the old program, it keeps wanting me to set up and account and when I go to the thunderbird program I find 4 different profile names and i guess it correspond with the times I have tried copying the profile back into the new pc. Can any one shed a light on this for me please.

I have an HTML signature that seems to work nicely when I compose a new email, but when I reply back to somebody who has replied to said email, my signature sometimes falls back into plain text mode, looking like a complete jumble. I get around this problem by copying the original signature and just pasting it in my reply.

A few key notes; - Account setting is set to use HTML as default, and it does. - The reply I get back still retains and displays the original HTML signature. - When I hit reply, that first HTML signature is still there, but the new signature is in plain text.

So to summarise; It's not processing HTML above the reply line, only below it.

Is there a way to absolutely force the composer to use HTML all the time everytime?

After a complete hard drive meltdown, I had to re-install windows (10 Pro) and then TB, which is now a blank slate. I have my old profile stored. But in it, my two primary e-mail accounts were POP3 (alongside a number of IMAP accounts) and I was never sure how to switch them to IMAP without having to change the e-mail addresses. And I always quickly moved e-mails out of the inbox into a series of local folders for storage. So pretty much everything I need to reference is in some kind of local folder. So my question is: 1. Is it possible to selectively import local folders from an old TB profile into my newly-installed TB? OR 2. Should I load my old profile and then try to change the two primary accounts to IMAP and can I/how do I do that while keeping the e-mail address? I currently have the new TB on my desktop and the old TB with my profile on my laptop with the "check for new messages" disabled on all accounts. NB I am 60+ and while relatively computer literate for my age, maybe somebody could ... to quote Tom Hanks ... explain it to me like I'm a 3-year-old :0 TIA for any help, Rebecca

Mail from a certain contact frequently (but not always) gets sent to junk. That contact is in my address book. I also have tried marking that contact as Not Junk", but no joy Seems like the junk mail handler is not working properly. Running 91.9.1 (64-bit) on Windows 10 Thanks. Jerry

As shown in the attached screen capture, recently these subfolders of "sent" have appeared to the left of the folder. They make the folders undeleteable. How do I get rid of them? I want to delete "sent" and create a fresh new "sent" folder.

Thanks John

Help me get access to my gmail through Firefox. I opened a new email account at [edited email from public] @proto.com but have not used it. Let's see if it works.

Hi there,

"When you open a link, image or media in a new tab, switch to it immediately" is happening - even though the box is unchecked. Only in favorites bar, not in web page or Firefox homepage Shortcuts (1 row or 2 rows) or Recent activity.

It's very irritating, so i hope there is a solution...?

I recently received this when trying to open Thunderbird:

You are about to override how Thunderbiird identifies this site. Legitimate banks, stores and other public sites will not ask you to do this.

Location: maul.aussiebb.com.au587 Get Certificate View

Confirm Security Exception Then this: This site attempts to identify itself with invalid information. Wrong stie. The certificate belongs to a different site, which could mean that someone is trying to impersonate this site. Both of my email addresses are affected.

I have to use my online webmail to send and receive emails, also my laptop is not affected.

Hi Mozilla Community I have attached a large-ish file 19.7 mb (a video) to an email. Pressed send and an alert comes up telling me I should use file share because ... and this is my issue .... the email is (now) 27 mb in size. I have updated Thunderbird, I'm using Imap and the TB version is 91.9.1 My computer is a two year old HP X360 laptop running Win10. I'm also using Bitdefender Total Security. I have tried several times with blank emails (no words) and a video attachment and some with just a few words and the attachment and also with other size attachments. Same result. This also happened with a 33mb pdf attachment, the alert saying the email size is 43mb I don't know where this extra 7mb or 10mb is coming from unless the alert calculation is wrong. Surely sending a blank email doesn't require this much data. I'm interested in others views and ideas. regards David

Hello,

I have a standard gmail, not a work email. I have used OAuth2 settings as well as attempted app password setup. Both have the issue of being unable to send emails.

I have deleted all Thunderbird user data, removed my e-mails, uninstalled Thunderbird, restarted my PC & installed a freshly downloaded version of Thunderbird, setup my e-mail using OAuth2 & the issue still persists.

I have verified in Gmail that Thunderbird has access to send, receive, & delete emails on the correct Gmail account.

I have recently had issues with my Gmail account while using Thunderbird. My issues are as follows:

I can receive all my emails but I am unable to send any form of e-mail.

My error is: "Sending of the message failed. The failed message could not be sent becausr connecting to Outgoing Server (SMTP) SMTP.GMAIL.COM failed"

I am using the recommended IMAP settings & I have performed this to verify it's correct:

Right click on gmail imap mail account name in Folder Pane and select 'Settings' select 'Server Settings' Under 'Authentication Method' change to 'OAuth2' then change the outgoing server info.

In left pane at the bottom select 'Outgoing server (SMTP)' select the name of the gmail server click on 'Edit' Alter the Authentication Method to say 'OAuth2' click on OK click on OK

IMAP Settings: Incoming Mail (IMAP) Server imap.gmail.com

Requires SSL: Yes

Port: 993

Outgoing Mail (SMTP) Server smtp.gmail.com

Requires SSL: Yes

Requires TLS: Yes (if available)

Requires Authentication: Yes

Port for SSL: 465

Port for TLS/STARTTLS: 587

In the desktop browser you can load the History tab, right-click a page, then click Forget This Site. Is there any way to do that in the Android version? It's needed for site development purposes.

I have for so long tried to let TB learn what is junk but nothing seems to work. I have also started taking the time to first mark as junk and then go into that junk folder and create a filter. My settings do not seem to make a difference. I have the filter set Mark before junk classification, match ANY of the following (so the @xxxx shows), and in the last section I have tried to set it to DELETE and also to MOVE message to junk folder on that email address. Nothing seems to work. I know there can be many junk senders from the same @xxx address but at some point I would think this "learning" process would take hold. Should I just give up on this timely filters and just mark as junk and then delete? Am i doing something wrong so my filters or junk settings are not filtering out new junk emails?

An issue with my email occurred yesterday. Suddenly, an incoming email from a known source, started coming in over and over again. Probably a couple of hundred times now. And it is blocking all other incoming mail - nothing since this started about 24 hours ago. Emails are coming normally through Outlook and on my iphone. How do I fix this. Thanks. I've tried re-booting but no luck there.

I am nearly 73 years old, and well affected by Parkinson's Syndrome and vision AND am loosing my ability to walk, rtalk, and see. I don't recall fiddly details anywhere as well as in the past.

I think it would be an advantage to see what I am typing. The simplest error with a password can wreak havoc with one's time and sense of self. If there is something I can adjust, or if a brief bit of coding may well be a splendid help.
