I switched my domain from long term USA hosting, to 1and1 in UK and now have a problem with my Mozilla Thunderbird email client. I set up my email addresses only with no web page file uploads. I decided 1and1 were not for me, so I cancelled my account the following day and removed all of my email addresses from the hosting account. Since then, emails continued to arrive from 1and1. Initially four emails IN folders were somehow created, which I deleted and have not reappeared. However the emails folders (?) which were in my account have returned and continue to do so almost immediately after I delete them as follows... No uploads and/or copy/paste? OK ? ? ? ? OK I have contacted 1and1 a number of times to ask them to clear my hosting account completely including all my files. They have assured me that my domain has been cleared completely and I assume they have done so. My ISP account is clear too. It is a mystery to me and I am somewhat concerned that a spammer or hacker has installed malware or similar on my PC. I have checked with my Panda anti-virus, Malware Bytes and AdWcleaner. Could you please advise. Thank you, Art.
