Specify your IP ranges in the allow network section (e.g., 213.39.39.2; 192.*.*.*)
Check that the following are configured correctly:
Check that the extension of the file does not match the blocked types (.exe and .bat are default blocked)
Verify that the hostname of the sender is not listed in the RBL servers ( sbl-xbl.spamhaus.org, bl.spamcopy.net ) You can also disable RBL support if too many files that are marked spam are valid.
Also if you have antivirus scanning enabled, check if the path to your AV-scanner binary is correct.
