SuSE Firewall does not like Postscript

Bonjour, Small problem I have a Postfix servor on a SuSE 7.1 host. It worked very well. I had the bad idea to try to install SuSE Firewall in /etc/rc.config.d/rc.firewall I had problem because my mail servor became unreachable. I suspected the reason to be the Firewall. I entered thus START_FW = "no" in /etc/rc.config and made init s -> init 3 to resettle the system. But SuSE 7.1 insisted on installing the Firewall. I had thus to "fill" the firewall daemon manually with rcfirewall-personal stop and then I could use again Postfix It's there another way to stop the Firewall Of course I'll have to reconfigure the Firewall because ther is a problem it stops smtp connexions -- Alain Barthélemy
