Problem sending emails

[Greenpalmer]

Hi, I can receive emails on my blueyonder account but cannot send. I get the following error:

Any solutions welcome!

@Greenpalmer Sometimes these are intermittent faults that resolve a few hours later.  Has this been going on for long?  Can you access the email address concerned via VM webmail at https://mail.virginmedia.com/

If not what error message do you get?

[Greenpalmer]

Thanks for the response Graham.

It's been going on for a couple of weeks now.

I've tried on VM webmail and yes - I can send and receive fine.

But still using my Outlook 2019 client I can receive but not send.

It would be helpful to see the error code returned by the SMTP server in this situation. From a desktop or laptop device open a Command Prompt and enter the following where username:password is replaced with your email address and password, i.e. richard.branson@virginmedia.com:rotavator-racecar-tenet-repaper:

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 unredacted or incorrectly redacted output here will likely 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 This is cmsmtp ESMTP service help
< 214-2.0.0 To contact postmaster send email to postmaster@virginmedia.com.

< 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 an unsuccessful result will look similar to the following:

⋮
> AUTH PLAIN
< 334 
> [Redacted]
< 525 5.7.13 Authentication Denied (VM320)
* Closing connection 0
* TLSv1.2 (OUT), TLS alert, close notify (256):
curl: (67) Login denied

Hi, I performed the operation suggested and received a lot of output:

The last few lines were the same as what you said indicated no issue, but there was a lot of stuff before that. 

I could not see anything that looked like a VM error code.

As no issue has been indicate we know: 1) authentication credentials are correct; 2) that the issue is specific to Outlook. I do not use Outlook so can only suggest reviewing account's SMTP settings, see Email settings change - Virgin Media Community - 3369438; hopefully more knowledgeable community members will contribute if further Outlook specific help is required.
