    It would be helpful to see what, if any, error code is returned by the SMTP server in this situation. From a desktop or laptop device open a Command Prompt 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: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:

    â‹®
    > 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 To contact postmaster send email to postmaster@virginmedia.com.
    < 214-2.0.0 For local information send email to Postmaster at your site.
    214-2.0.0 For local information send email to Postmaster at your site.
    < 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:

    â‹®
    > 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
