Hi, i am getting the following error message when I try to send emails. This applies to all messages I am sending. Both on my windows and android account

 

Message could not be sent to the following recipients: [*****.**wer@talktalk.net] (554 - 554 5.2.0 4OKAhvPLRp7QX Sender Denied TT608

 

Any Ideas appreciated.

Hi @TropheusJim 

 

The error code indicates it's related to the mailbox status but the actual error is undefined. Sender denied TT608 is the description but even this is not precise enough to say what the actual reason is.

 

The obvious causes are:

  • The mailbox is blocking your email address
  • The mailbox says your message is too large (oversized attachment usually)
  • Your IP address is blocked

The first is under the control of the recipient. The second and third are under your control. You might try getting a new IP address allocated if you are presently allocated a dynamic IP address i.e. switch your router off for a few minutes (20 minutes if your connection is fibre).

Tried switching off router. Did not work. Will this be connected to the fact that recently I have been receiving a few "returned" e mails from addresses to which I never sent e mails.

The addresses are foreign names and end .eu or .ru

Hi @scabbycat 

 

I'll reply to your post (and Private Message) on another thread so that we can follow up with you individually.

 

But for you and maybe for @TropheusJim I'll say that the receipt of Mailer Daemon bounceback error messages, together with the Sender Denied (TT608) is a good indication that your email account may have been compromised or that the email is being spoofed. Compromised or spoofed accounts If spammers are using your email account then that's one reason for the Sender Denied response.

 

The email account password must be changed to secure the account and positively prevent spam emails being sent from the account.

 

Password recovery may have been set up for the email address with an alternate email and or mobile number. Please do try the Reset your Password option. Other than the reset to the account itself, if there are alternates listed, see if you recognise them from the hints and if you do have access to the alternate email or mobile then please use either to reset the password.
