Not able to send emails from blueyonder email address using Apple mail

[tc14]

Hi,

Unable to send emails from this address from my Mac using the Apple mail app.

I get the following message -

The attempt to send data to the server "smtp.blueyonder.co.uk" failed.Select a different outgoing mail server from the list below or click try later to leave the message in your outbox until it can be sent.

The 2 servers listed are Blueyonder and iCloud - and both are described as Offline.

Any idea how I can fix?

Any help much appreciated - I've had this problem for about a week. Thanks

Try the following:

• select Window > Connection Doctor
  FYI Use Connection Doctor in Mail on Mac – Apple Support (UK)
• select Show Details
• select Check Again and wait for check to finish
• select Show Details pane
• press ⌘ + F and search for the text VM
• post just the VM error code here

Hi - I don't get anything when I search for VM in the Show Details pane.

Is there anything else I should search for that will help explain what the issue is?

Thanks in advance for your help!

It would be helpful then to see what, if any, error code is returned by the SMTP server in this situation. Open Terminal.application and enter the following where username:password is replaced with your email address and password, i.e. richard.branson@virginmedia.com:Y54kpX5g:

curl -v smtps://smtp.virginmedia.com -u username:password

Do not post the resulting output here but instead review it for possible reported causes, i.e. VM error code; choosing to ignore this advice and posting the output here unredacted or incorrectly redacted may reveal your email address, password and / or public IP Address.

FYI if there is no issue then you should see the following output from the curl command:

⋮
> AUTH PLAIN
< 334 
> [Redacted]
< 235 2.7.0 SMTP350 Authentication successful for user [Redacted]
> HELP
< 214-2.0.0 This is cmsmtp ESMTP service help

< 214 2.0.0 end of HELP info
214 2.0.0 end of HELP info
* Connection #0 to host smtp.virginmedia.com left intact

Otherwise unsuccessful will look similar to the following:

< 525 5.7.13 Authentication Denied (VM320)
* Closing connection 0
* TLSv1.2 (OUT), TLS alert, close notify (256):

Hey tc14,

Hi - thanks for this - I've been able to do this - 

No VM error code as such - but the output stated that VM had blocked my connecting IP as too many bad emails have been sent.

Also - got unexpected smtp-server response: 421

Do you know how to resolve this?

Thanks

Too many bad emails have been sent via your public IP Address and Virgin have blocked access. Consider following the advice here My Virgin Media account has been hacked and then going to https://netreport.virginmedia.com/netreport/ to request a delisting:

• select an abuse type of Email Sending Errors from drop down list
• select an abuse form of Other from drop down list
• paste the complete error message into the Log Evidence area
• enter your name into My name field
• enter your email address into Email address field
• select Submit button

Hopefully de-listing will occur sooner rather than later but if not post back here to have the issue flagged to the forum team.

Hi @tc14,

Thank you for expanding on this. Has the advice offered by @用心棒 in their last post here helped at all?

Thanks,
