So, what about postfix itself? Did you really analyze every line of the source code? > It would be greate if you could help me to customize > "smtpd-policy-template" for me The policy delegation protocol documentation is very helpful and clear. To be honest, your first attempt shows that you should think about engaging someone with experience in writing perl-network code or really take some more time for studies. No offence really, but there are several ways to create serious security flaws with own code, if not reviewed by experienced programmers or a bigger audience. You can never trust input if you are on public networks! An example: The more complex your work gets, you may want to log several actions of your code. The first public postfwd versions had a format string flaw, because older versions of the Sys::Syslog functions were not to happy about "%"-characters in e-mail addresses - same for printf and so on. Don't forget, that your mail system may become unavailable, if the policy service crashes. Regards, Jan
