I have successfully(?) connected MS Outlook 2010 to the little publicised BT Yahoo IMAP server. Email is being sent and received without any issues at all. However, all of the incoming mail in the inbox lists my email address attached to the header rather than the senders. The content of the email is correct and if I choose to set up a new rule to file the incoming email, the correct senders email address is recognised by Outlook 2010. It appears at face value that I have a display of address issue rather than anything else and I also suspect that it is simple to fix. Alas I cannot find anything that I may have incorrectly configured.
Looking for some expertise out here......................
