#359 foreign X-Virus-Scanned removed

[Armin Fuerst]

Amavis 0.3.12 seems to remove foreign added
"X-Virus-Scanned" lines, which can lead to problems
if the foreign software created multiline-comment.
An example for this is clamav-milter. As a consequence,
all but the first line of the clamav-milter X-Virus-Scanned
lines are appended to the subject of the message!

As a quick workaround, I changed line 240 to
$X_HEADER_TAG = "X-Amavis-Virus-Scanned";

Yes, that was a design decision that needs to be reviewed. The
hostname should probably appear in this header.
