Hi.
Amavis skips invalid headers:
X-Amavis-Alert: BAD HEADER SECTION, MIME error: error: part did not end with     expected boundary; ; error: unexpected end of parts before epilogue

Pass letters from intruders.
How to block such letters?
Thank.

Re: block letters in spoiled headers

Do you want to block bad-header emails?
If so, update /etc/amavis/conf.d/50-user, and set:

$final_bad_header_destiny = D_DISCARD;

Note: you should find it present in this file, just update the value and restart "amavis" service.

If you're running iRedAdmin-Pro, it's easy to update it with one click in "System -> Anti Spam -> Global Spam Policy" page.
