Just a couple of days ago - all of a sudden - all of my emails are going out as " On behalf of" because my outgoing mail is being used to send my emails @company.com. I am using Bell's outgoing server to send email. I have not had a problem using Outlook 2003 and now Outlook 2007 until now. We do not use Exchange. To summarize, I have a company email account that I access through Outlook 2007. It uses my Bell internet account to send the emails. All of a sudden, all my emails say " email@example.com; on behalf of; My Name [firstname.lastname@example.org]" in the Send field. The only solutions I've seen involved Exchange servers which I do not have. How do I get rid of this?
