I have already posted this issue in a reply to another user, but would like to give it wider circulation.
I regularly send out e-mails to a distribution list of about 40 people who use a range of internet providers. About a week ago e-mails sent to two of the people, the only ones who use talktalk, were returned to me after a couple of days marked 'undeliverable' and 'timed out'. The same people receive e-mails sent by me to them using gmail accounts, and I have received e-mails from them to my ntlworld e-mail address.
I spoke to a Virginmedia adviser this afternoon and, after consulting colleagues, she told me that there is some sort of dispute between virginmedia and talktalk, and talk talk have 'blacklisted' e-mails sent from virginmedia servers. Apparently, the two service providers are trying to resolve this dispute (I wasn't told what it is about) with a view to restoring the service between them, and we will be informed when it is all working again.
I would be interested to hear from anyone who knows more about this.
I think your title should have been e-mails to TalkTalk users.
I don't know whether it's down to a **bleep** for tat dispute, and if I were working for VM I definitely wouldn't have used the word dispute when describing what's happening.
Based on the amount of time it's taking for mails to come back, it looks as if TalkTalk are following Virgin Media in employing rate limiting on their inbound mail servers. Virgin are raising this with their Postmaster who will no doubt be in contact with TalkTalk's over this at some point. How long it will take to sort will depend on TalkTalk. Hopefully they'll be more proactive than Virgin's have been.

Welcome to the forums, I am sorry to see you have been having trouble sending emails to Talk Talk customers.
Please pop across the header of the failed sent email, which should be included as an attachment in the failed delivery notification/ bounce back message via PM (Purple Envelope, top right hand corner).
