Checksum error

[Lima Union]

Hi!

I'm currently testing RHEL4 + SA 3.0.4 + amavisd-new + Postgrey + Postfix. While running amavisd in 'sa-debug' mode, whenever I send a mail with a binary file I receive the following message:

LHa: Warning: Checksum error (LHarc file?) Inappropriate ioctl for device

What may be wrong here ?
Thanks in advance for any advice.
