Email will not send. Message-- "Sending of the message failed. An error occurred while sending mail. The mail server responded: Email rejected. Please verify that your email address is correct in your account settings and try again." I am not sending to another person but testing with my personal email. Thank you.

Goodmorning,

I have been using thunderbird for years now and I love it it keeps my accounts all together and I like that. however, I am trying to set up a new email account gamingconsole360@outlook.com and I keep getting an authentication error I am trying to set it up as a pop3 account but I get stopped before I get that far some sort of authenticaten error. I tried manual setup and this is what I see in the hostname box .outlook.com and it says under it Hostname empty or invalid. Only letters, numbers, - and . are allowed Please help

I have recently installed Thunderbird to help me with my overfull Yahoo account. I installed it using the default Yahoo authentication which seems to work fine. Since Yahoo exposes at most 100,000 messages in any one mail folder, and my inbox had over 250,000, my goal is to spread those out amongst a few different folders so that I can manage the inbox more effectively offline. To that end, I set up a couple of saved search folders, each of which selects e-mails within a two-year date range. Incidentally, each only selects about 1,000 messages at a time, not the 40,000 or so each of those time periods seem to contain. When I use my Ctrl-A shortcut to select the messages in one of the 'search' folders, then move those messages to my Yahoo mail folder under my e-mail account, the messages initially are wiped from the saved search folder, but after a few minutes they all return!

Incidentally, the saved search folder has the same name as the folder I'm trying to copy the messages to, but the search folder is under the Inbox, and the other folder is 'beside' (not under) the Inbox.

Let me know if there is a more efficient and effective way of doing what I want. Ultimately, I want well under 100,000 messages in my Inbox.

Thank you

I have new e-mails from some company. I can search for the company and the e-mails show up (as recently as today) but in the list I only see e-mails as recent as 35 days ago. I see TB periodically download new messages but they don't show in the list. I have searched all over for a solution and nothing has worked. I have no Message Filters and I have no Quick Filters active. I have tried both repairing and compacting the Inbox. Does anyone have anything else I can try?

I tried everything and I mean everything and I am still getting this error shown in the image attached. Can someone help?

• I removed saved passwords
• Un installed and re-installed thunderbird
• created new profile

P.s. This is an office 365 account

There used to be a way to block sending an e-mail to a particular recipient, how can I do this now? When using reply to, there is a defaut address that is used that causes an error. I need thunderbird to block this recipient ( only from sending as they are the default sender ). Thunderbird used to have this option for "sending rules" but it appears to have been removed.

Whenever I attempt to download waiting emails I frequently get the message: "The STAT command did not succeed. Error getting message number and sizes. Mail server mailhost.zen.co.uk responded: Mailbox unavailable." This is a relatively recent occurrance - what can I do to resolve it?

Mail filters for custom headers like List-Unsubscribe, Authentication-Results or Received-SPF copying messages from IMAP accounts to Local Folders do not work on the Yahoo! IMAP account. For example:

filter1.jpg: name="_Inbox2: List-Unsubscribe <https" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox/_Inbox2" action="Stop execution" condition="OR (\"list-unsubscribe\",contains,<https)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

filter2.jpg: name="Spam: Authentication-Results dkim=unknown | Received-SPF fail | X-Antivirus-Status Infected" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Junk" action="Stop execution" condition="OR (\"authentication-results\",contains,dkim=unknown) OR (\"authentication-results\",contains,dkim=perm_fail) OR (\"authentication-results\",contains,dkim=none) OR (\"received-spf\",begins with,fail) OR (\"received-spf\",begins with,softfail) OR (\"received-spf\",begins with,none) OR (\"x-antivirus-status\",is,Infected)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

But filter3.jpg for Subject works well: name="Inbox" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox" condition="OR (subject,doesn't contain,t[k\6iq69pd+}'cr)" (copies all remaining messages from IMAP folders to Inbox on Local Folders)

(the snippets above are fragments of the msgFilterRules.dat file)

Filters1 and 2 work well on other IMAP accouns, like for example wp.pl. So this is about Yahoo or something is corrupted. My question is, what wrong is here ? And by the way - how to create filter copying all messages from IMAP to Local Folders ? Is better way then filter3 looking for random string in the subject or somewhere else ? Thank you.

I'm using Thunderbird 149.02 to make a local copy of all folders, messages and attachments on my yahoo mail account. I don't yet see an obvious way to issue a command to Thunderbird to accomplish this.

I'm using export.imap.mail.yahoo.com as the IMAP server as some of the folders have >10000 messages (none have >100000 messages, and there is no significant real-time email arriving to the account while I do this procedure.)

In settings/offline settings I have "automatically follow detected online state" and "download messages for offline use when going offline [yes].

In account settings/synchronization & storage I have Disk space: Synchronize all messages locally regardless of age"; "to recover disk space, old messages can be permanently deleted..." I have "Don't delete any messages" and "Always keep starred messages"

With these settings, I've tried (from the main menu) File -> Offline > Download/Sync now, then "Download and/or sync..." I have selected Mail Messages, and the Select button takes me to a table where I have selected the main account folder and all sub-folders.

With these settings, Thunderbird appears to go through some of the folders and downloads messages from, them, and after a while says there are no new messages (I don't have the specific text, but it ceases interacting with the server". If I repeat the Download/Sync now procedure, it appears to download more messages, will continue for a while, then stop in the same way.

When I compare the size of Thunderbird's local account folder, it appears to grow after each of these iterations, but is (after half dozen cycles through this) has only reached about 2/3 of the total stoage size reported by Yahoo. While I understand the storage mechanisms would differ significantly between yahoo and Thunderbird, I don't believe I've found a single sure-fire way to accomplish what I set out to do in the first place (which is get a complete copy, through IMAP, of all emails, folders and attachments.

What am I missing?

Thanks,

Dave

I get this message everytime I try and send emails

I get the messgae 'Unable to write email to the mailbox...make sure the file system allows you write priviledges and you have enough disk space.' When I looked at the errors Thunderbird recorded I found thei:

I recently had to restore my thunderbird app as I had issues with my laptop. I do not run Avast...I have tried the 'repair' option in folder properties in thunderbird. Nothing seems to help. I would appreciate any assistance you can give me. I have been using Thunderbird for....well it has been aloooong time and I have never had any issues with it previously. I am running WIn 11 Pro.

I have connected a Google Workspace (Gmail) account to Thunderbird, let's call it scott.harper@myorg.org. I am able to send, receive, and reply from this account as expected.

In my Google Workspace configuration, I have an alias address forwarded to my account, let's call it info@myorg.org. I receive messages addressed to "info" just fine. But when I send or reply to messages addressed to "info", I'm running into a problem.

In the Account Setting I opened Manage Identities, and added info@myorg.org as an alternate identity. I then edited the Private Data for that identity so that the "Reply from this identity when delivery headers match" option is checked, and set to match info@myorg.org. See attached image.

When I reply to an incoming message, the From field appears to be (sort of) correct... it shows from info@myorg.org, but next to it (in italics) is the primary account identity, scott.harper@myorg.org. See the other attached image. This is also the case when I compose a new message and select the info identity.

In both cases, when the message arrives at the destination inbox, it is from scott.harper@myorg.org instead of "info".

I'm assuming I don't have the matching rule, or some other setting configured correctly. Would appreciate any other tips/ideas.

Hi I have a hotmail account registered to my Thunderbird account, I receive mail. OK but it won't send mail comes up with error "unable to connect". Followed by:- (Should be a screenshot but it wont load?)

which says "Sending message failed The message could not be sent connection to server SMTP timed out."

This is a new occurrence not experienced before?

If I go to webmail it will send OK?

I started getting this message when I attempt to download my email to Thunderbird:

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

I am using AOL with the address: rc.woolfenden@verizon.net on a Windows 11 platform with a 1TB solid state hard drive. I have never encountered this issue before.
