The "Microsoft Updates" (approx. 150kB Mails) were not
handled correctly.
Reason: the mails contains headers in unusual capitals.
/usr/share/perl5/AMAVIS/MTA/Maildrop.pm is used to
extract Header information with case sensitive regular
expressions.
Both original lines:
if (/^From: *(.*)$/) {
if (/^To: *(.*)$/) {
could be changed to
if (/^[Ff][Rr][Oo][Mm]: *(.*)$/) {
if (/^[Tt][Oo]: *(.*)$/) {
to accept From: and To: in all case variations.

Or, even better:
if (/^From: *(.*)$/i) {
if (/^To: *(.*)$/i) {
