Don't know if this is the exact problem, but I tidy up the report before
inserting it into a header:
my $fixed_report = $report;
$fixed_report =~ s/\n+\z//g; # fix for multiline header
$fixed_report =~ s/\n/\n\t/g; # fix for multiline header
action_add_header("X-Spam-Report","$fixed_report");

Subject: [Mimedefang] mimedefang/SA inserting blank header lines
I'm having a very occasional problem with sendmail/md/sa
inserting lines consisting of one blankspace char into the headers of
an email; such messages are rejected occasionally by certain servers
on the basis that they may cause outlook to drop its trousers[1],
muttering something about a "blank folding" vulnerability.
These lines seem to occur after the X-Spam-Report: lines, just
before X-Scanned-By. An example (with mangled addresses to protect my
users and their correspondents) can be seen at
