Emails not sending, but receiving is fine

[nomispc]

I've seen other emails on this subject and replied to a couple, but I've decided to start a new conversation since I wasn't getting any response.

I tried the 'curl' option suggested by people and found that I've got a 421 error. Apparently VM has "blocked your connecting IP **********. Too many bad emails have been sent".

It advises visiting "https://netreport.virginmedia.com/netreport Section Email Sending Errors to request delisting", but it's not clear on that site quite what needs to be done.

As well as resolving this, I'd like to know why it happened, and if it's likely to happen again.

Any help will be most gratefully received.

To determine why send is failing 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:

⋮
> 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

Otherwise an unsuccessful result will look similar to the following:

⋮

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

Hi there,

I gave the main error code as 421, but here's pretty much the whole thing with details redacted etc

* Trying IP ref

* Connected to smtp.virgin etc

* schannel: disabled automatic use of client certificate

schannel: server closed the connection

421 csmtpl-..............unified.services. Virgin Media has blocked your connecting to IP **********. Too many bad emails have been sent. Visit https://netreport blah blah

* Got unexpected smtp-server response: 421

* Closing connection

* schannel: shutting down SSL/TLS connection with smtp.virgin etc

curl: (8) Got unexpected smtp-server response: 421

There isn't any more data, so I hope that helps.

Go to https://netreport.virginmedia.com/netreport/ and:

• 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.

Also consider following the advice here My Virgin media email has been hacked | Virgin Media Help

Thanks for that. This may sound like a foolish question, but do I assume that this time I do paste the entire error message including my IP address?

Yes; paste it verbatim (including IP Address)

Thanks. I've just received a holding reply, so now I guess I just wait and hope.
