Does anyone know how email could come from the postmaster account on the SME server? I have gotten several different mail rejections (because I am the admin and all the mail rejects come to me) saying that there was a virus in an attachment. The strange thing is, in the content of the email, there is a hyperlink to our website, the email directs a person to click on the link to access their account information. I have never sent any emails out from the postmaster account, and I have never seen specific email spoofing where they were able to use the actual domain and link in the email. Does anyone know where I would start to try to track where the problem is? Thanks.
