Many of my customers are unable to send me email, and have been receiving bounce-backs for at least two weeks. An increasing number are saying they don't receive my emails (though they do if I send via gmail's servers). It looks like TalkTalk has had a range of IP addresses (including mine) blacklisted. When can this be resolved, please?
This is a typical bounce-back header (although most customers do not use livemail).
