It does not matter whether I use an email client, VM's webmail, or Android, for at least a month now I have been receiving old emails from the 26th of July 2019, and only from that date. In my email client they arrive in the Inbox already marked as junk, so I go to the webmail and put them on the blacklist, which updates the list.
Yes I have read MissPasco's post. But my issue is that I am receiving mails from only the one date in July, They appear in my email client, Thumderbird, already marked as spam, but I have to back into Webmail and again add them to the blacklist. !
Thanks for the help. At the moment I have not got one to send you the header from because as soon as I receive them I put them on the blacklist then I delete them. But as soon as I get another I'll send you the header from it.
