you are trying to send hotmail mail using an outgoing server other than that specified by hotmail. Perhaps try using the correct outgoing server.

Each of these things you have mentioned all have their own SMTP servers. the only email domain you should be sending through mail.com are email addresses that end in @mail.com. Through talktalk it would be @talktalk.com.

Please could you please do the following:

  1. Open the menu Fx57Menu > Help > Troubleshooting Information, then click Copy text to Clipboard.
  2. Open a reply to this post, and paste your troubleshooting information.

Ok I have edited that to remove the full email addresses, but it looks to me like you settings are a dogs breakfast

Right click any of your accounts in the folder pane and setting settings from the menu.

in the entry in account settings for Outgoing server (SMTP) ensure you have an entry for each and every email address you think you want to send mail from.

You should at least have SMTP servers for Gmail, yahoo, outlook/Hotmail, BT internet, talktalk and mail.com. That is based on what you have said about email addresses you are using.

Now to address the correct way to use those multitudes of SMTP server entries. How do you actually become aware you have mail in those accounts? Are the all forwarded to another aggregation or what. I need to understand to offer advice that is not just weird. account?

Hi its me again, guess what, sent about a dozen emails worked fine but now its gone back again. I think the only way to sort this is to sort out the dog's breakfast of my settings as you put it. So where do I start?

I presume you are only talking about the mail.com account. The settings look correct for that account - assuming you have not altered anything from what is shown in images.

Please make sure you have subscribed to see the 'Sent' folder and all other required folders. Right click on 'mail.com' mail account in Folder pane and select 'Subscribe'. Click on 'Refresh' Select/highlight all the folders you want access to. click on 'Subscribe' click on 'OK'

Then make sure you are actually using that 'Sent' folder. Right click on 'mail.com' mail account in Folder pane and select 'Settings' Select ' Copies & Folders' Select 'Place a copy in' Select : 'Other' and choose the 'Sent folder on mail.com account' click on OK

restart Thunderbird. See if all is working ok.


If not: Try removing and resetting your password. Menu icon > Options > Options > Security > 'Passwords' tab Click on 'Saved Passwords' Click on 'Show Passwords'

You should have two lines for each mail account. The incoming starts with imap://imap.mail.com.... The outgoing server will start with smtp://smtp.mail.com... Username should be full email address in both entries. Password should be correct for both entries.

So for eg: 3 accounts, there should be 6 entries. If you have more than six then remove surplus/erroneous ones.

Locate the smtp line for mail.com server. Right click on that line will provide you with options to 'Edit Username' and 'Edit Password'. Remove content and retype the correct information. Username should be full email address. Password is exactly the same password you use to access webmail. It is case sensitive. Make sure there are no hidden blank spaces either before or after and do not use a puntuation mark - so easy to do :)

click on 'Close'

Click on Ok if Options is shown in window.

Exit Thunderbird and wait a few moments for background processes to complete.

Start Thunderbird.

Change your outgoing server settings to the ones recommended by mail.com: smtp.mail.com on port 587, STARTTLS security, authentication = normal password, User Name = email address.

OK and now back to square one, the email address on the attached is correct, the same error message comes up for at least another 6 I tried to different recipients all of whose email address's are correct. What the hell is going on? Is it time for me to dump Thunderbird? James

A mailbox could become 'unavailable' if the recipient's mailbox had reached its storage limit or had been closed, but I doubt that is the case for all 6. Maybe your messages are being blocked due to spam coming from the same mail.com server. Do you get the same error when sending to those same addresses, but from a talktalk account?

I've had this same rubbish with my talktalk emails on more than a few occasions in the past.

Unfortunately, 'mailbox unavailable' is one of unhelpful messages the recipient server offers that really can cover serveral reasons.

Check all server settings for incoming and outgoing are correct. Check username and password are correct.

Typical reasons: Recipient email address is a non-existent account - perhaps a typo error in the email address. Recipient email address was valid but is no longer or is currently suspended. Recipient email address is still valid, but has reached it's quota and can no longer receive emails. Once recipient has deleted some emails, the account can thenstart to receive again. Recipient’s email server is having a problem of some sort and can’t deliver the email. This usually starts to work again after a few hours.

The message you are sending looks like spam to the recipient’s email server, so is refused by server. Things to check: Make sure email has a Subject. If sending using Bcc, make sure you have one email address in a TO field, even if it is your own. If composing in HTML, make sure you are sending in both Plain Text and HTML as some servers like plain text as an option. In Thunderbird:

  • Menu icon > Options > Options > Composition > 'General' tab
  • click on 'Send Options' button

'Whens ending messages in HTML.......'

  • select 'Send the message in both plain text and HTML'
  • click on 'OK'

Does email have several links? This may be triggering the server to think it is spam. Do you have a Signature with an image which also has a link? Test by removing the signature and replacing with a simple text signature.

Your email hasn’t been accepted for IP problems or blacklisting. You could try forcing your computer to use another IP address. Check to see if your IP address or it could be the server 'mail.com' IP address has been blacklisted.
