Hi, 

I'm suddenly unable to send emails, and this error message has popped up.

An unknown error has occurred.

Subject ''

Server Error: 421

Server Response: 421 csmtp3.tb.ukmail.iss.as9143.net cmsmtp Sorry your IP is active in our local abuse blacklist. Contact Virgin Media abusedesk for delisting requests.

Server: 'smtp.virgin.net'

Windows Live Mail Error ID: 0x800CCC67

Protocol: SMTP

Port: 25

Secure(SSL): No

I've checked my IP on MXtoolbox and it's only blacklisted with SORBS DUHL and Spamhaus ZEN which Virgin has said is normal and shouldn't cause any problems with sending emails.

When I go to the abuse desk page there is nowhere to request my IP being delisted or anywhere else to ask for help. 

Does anyone know how I can solve this problem?

Thanks

I think Virgin Media has created their own blacklist to protect their outbound servers.

The Forum Team should be able to assist here, but it can take them a while to get to the thread.

However I would point out that your server settings are out of date as well.  Not to mention you are using software that has not received any security updates since 2016.

Consider changing your email client.  There are many out there, but Thunderbird remains free and easy to set up.  Primarily because Virgin Media have set up autoconfig information for you.

Hi sheran1961, thanks for your post.

Sorry to hear you've encountered this issue with sending emails. 

So we can look further into it - I will get in touch via PM to confirm a few details & raise it with the relevant teams for investigation. Just look out for my PM  (the purple envelope) and we'll take it from there.
