4) Description of Vulnerability

Secunia Research has discovered a vulnerability in ArGoSoft Mail Server
Pro, which can be exploited by malicious people to conduct script
insertion attacks.

Input passed in various e-mail headers (e.g. "subject" and "from") is
not properly sanitised before being displayed by the "View Headers"
functionality. This can be exploited to insert arbitrary HTML and
script code, which is executed in a user's browser session in context
of a vulnerable site when viewing the headers of a malicious e-mail.

====================================================================== 
5) Solution 

Update to version 1.8.8.6 or later.
