Protocol version is 73, not the 2 as this script expects.

Hi all

I keep getting this error "Protocol version is 73, not the 2 as this =
script expects." when setting up the catchall "+" user alias.
Anyone know what the problem might be ?

Apache_1.3.20
PHP-4.0.5
Redhat-7.1
Squirrelmail-1.2.0-rc2.tar.gz

Regards
Dennis
