ISS Proventia email overflow

["Albert R. Campa" <abcampa () gmail com>]

Hi guys,

I am getting spurts of events trigerred by ISS Proventia, with the
following vuln description:
Vulnerability description
In buffer overflow attacks, an attacker supplies data that is longer
than the available space to hold it. For stack allocated variables,
this usually means the attacker can corrupt other variables and
eventually modify the code that is executed when the function in which
the overflow occurs ends.

They are from a trusted mail server so its not being blocked.

Do you think this is just a true false positive or is this trusted
mail server sending bad packets?
