[sqwebmail] Unable to launch sqwebmail from external

[CH Quek]

Hi,   When I try to launch the sqwebmail from a external broswer using eg. http://my_website/cgi-bin/sqwebmail I got an error: -------------------------------------------------------------- Server error! The server encountered an internal error and was unable to complete your request. Error message: malformed header from script. Bad header=� : sqwebmail Error 500 ----------------------------------------------------------   But when I use the qmail server, I do not encounter any error eg. http://localhost/cgi-bin/sqwebmail   I'm not sure if the firewall is causing the problem. Is there any particular port that is required for sqwebmail to run?   Rgds CH
