Settings for what are blocked are your amavisd.conf file. 
Search for $banned_filename_re or $banned_namepath_re 
(probably only one of these is used).  Edit these settings as 
you see fit, see the RELEASE_NOTES and the amavisd.conf-sample 
for instructions and hints.

Brackets "[ ]" are not blocked.

Maybe the file has a Microsoft Class ID extension -- something 
like "{755410F0-3C4C-485D-8A90-B248BE8C39CA}" -- such files 
can be used to force a particular program to open an 
attachment and it's dangerous to give an outsider such control 
over your system.  However, the braces themselves are not 
blocked, only when they appear in a string that looks like a 
CLSID.  If you need to allow these unsafe files, change your 
$banned_filename_re or $banned_namepath_re.
