sqwebmail and boa webserver

[matteo@spark.homeunix.org]

Hi to everyone.
I am new to this newsletter, I tried to find something that answers to my question on the 
debian site, but didn't find anything.
I'm trying to set up sqwebmail through boa webserver using the packets downloaded for 
the current stable debian distribution, but when I connect to the link:

http://<my server>/cgi-bin/sqwebmail

I get an HTTP 500 Error: internal error of the server.
Looking at the /var/boa/error.log log I see this error string:

cgi_header: unable to find LFLF

I don't know anything about cgi or similars, so I don't know exactly what I have to do to 
make it working.
I searched at sqwebmail site and at boa site finding nothing... Could someone please 
explain to me how I can get a webmail server working?
Thanks.
Mat
