need some helps with kolab 2.2

[Reza Issany]

Hello,

Sorry for my bad english. I'm a french people.

I've just made a fresh installation of kolab 2.2 on a debian server and 
I could not
send or receive any email messages.

The error log is :
Jul 18 19:50:54 xxxxxx <info> postfix/smtp[5326]: E0CF29276:

I've already tried to lauch it manually using  /kolab/sbin/clamd 
--config-file=/kolab/etc/clamav/clamd.conf
but it can't start : Illegal Instruction

Any idea to resolve the problem ?

Thanks for your helps.
