smtp.blueyonder.co.uk cannot send email

[zedi66]

Hi I am unable to send email from my smtp.blueyonder.co.uk email account I only noticed this today is there a known problem which will be resolved. I am able to receive email I just cant send.

[用心棒]

Whilst troubleshooting the issue send urgent emails via webmail

It would be helpful to see what, if any, error code is returned by the SMTP server in this situation. On a desktop or laptop device open a Command Shell in Window or otherwise a Terminal. 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 and then post just the redacted part here or the VM error code.

Thanks for that I ran the command and can't really see a VM error code in there.  Also don't understand what you mean by the redacted part?

Following curl returns VM320

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

 By redacted I mean remove any confidential / personal information in the resulting curl output, i.e. in the above example the text [REDACTED] replaces what looks like a string of random character but is actual a simple encoding of email address and password (aka authentication credential); the encoding aids transmission and not security so is trivial to decode.

The curl output suggests the text highlighted below is missing::

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

FYI: remember to replace username:password with your email address and password separated with a colon, and to only post the VM error code.
