Interesting Error - Can't use string ("1909") as an ARRAY ref while "strict refs" in use

Glenn has taken a look at this, and the problem doesn't arise on his 
Perl 5.10 systems at all.
And as he pointed out, it's my Perl not his :-)
So is this something to do with Ubuntu's build of Perl?

However, you could edit that line of PFDiskStore.pm and change it from this:
    while (${@{$body}}[scalar(@{$body})-1] !~ /^\s*$/) {
to this:
    while (${@{$body}}[int(scalar(@{$body})-1)] !~ /^\s*$/) {
You should probably comment out the next line (the "print" statement) too.

What I originally wrote is perfectly valid Perl, but it's managing to do 
the "-1" but then is leaving that as a string "1909" instead of using it 
as a number 1909 in the array reference.

Let me know if that helps. You'll obviously need to restart MailScanner 
after making that change :-)

Jules.
