How to get rid of “mailscanner has detected a possible fraud attempt from…”
this warning text is generated by mailscanner, a virus/spam/security filter that may be used by a number of your recipients.In an attempt to warn against possible “phising” attacks, it compares the link text to the actual link.
so if you have a website address in your link text, mailscanner will try check whether the actual link (at least the domain portion) is the same as the text.
To avoid these mailscanner errors issue, you can either
turn off link tracking, or stop using a url as the link text.
