I use WLM on Windows 7 for my main email (ntlworld.com) address. I don't keep an address book, i just reply to the latest email from whoever in my inbox. I am on one list of old school friends, pretty much all the rest in my inbox at any one time are from individuals or companies.
Recently, i have been receiving a lot of 'delivery failures' for emails that i have supposedly sent to addresses on this list. Some on the list have confirmed they have been receiving spam from my address. This list activity is the only malfunction i have noticed in WLM. I have a hotmail account and a yahoo account that both seem to be performing fine.
My ISP suggested i changed the passwords on my ntlworld accounts (I have two) and i did that under their guidance over the phone the other night. Within minutes of doing so i got yet another batch of bounced emails.
The only difference was this time instead of "Mail delivery failed: returning message to sender", "Undelivered Mail Returned to Sender" or "Undeliverable: Fw: new message" in the subject line, i got "Warning: message XXXXXX-XXXXXX-XX delayed 24 hours".
My ISP suggested i changed my passwords again and when i reiterated that i had just done so and it had made no difference, he insisted that this was all he could suggest or to "open another email account". He did say that my PC must be infected with a virus, but i scan regularly with avira and malwarebytes and occssionally with ESET and Adwcleaner.
Can someone please explain in not too technical fashion what has happened and more importantly how i can fix the problem?
