Ady-TalkTalk replied today on another topic that you saw that TalkTalk have done their bit and therefore the server reputation should gradually improve such that Gmail will have no reason to park genuine posts in any spam folder.
However, my talktalk.net mails sent via TalkTalk Mail webmail are still being dropped into Spam by Gmail.
NB I've not had the mail marked as Not Spam just for the purposes of testing. If you have contact with your recipients e.g. using Gmail to Gmail then tell them to mark your messages as Not Spam and that will return those to the Gmail Inbox and all future messages will arrive in the Inbox.
