Port 25 is smtp !!!

Ther is someon, which like to use your Web-Server as OPEN
SMTP-RELAY...

Somtimes you find misconfigured Webservers which use a MUA
for sending error-messages. and if the Admin forget to deny
relaying, the Webserver can be used to spamm...

If you have a MUA installed on the web server, please check
the config !!!

IF not, disable the smtp service.
