Hi We have been running lsmtp with listserv for sometime now. About 3 months ago we installed xwall in on the same machine to handle the extensive spam connections we were receiving on the server. Everything is working fine now no downtime, but im a bit apprehensive on removing lsmtp of the server. It appears if you install lsoft and tell it to use lsmtp it does not install listserv smtp service. Also to thru another equation into the picture we just started running our listserv incoming traffic thru our barracuda. So I want to do this in stages, i want to remove lsmtp from the system but i want to make sure i can start listserv smtp after doing such. xwall takes over port 25 so i need xwall smtp to listen on another port ie 24. Then after that is accomplished i will look at removing xwall from the picture once im sure propagation has occurred. also is there a setting, im sure there is somewhere to have lsoft only accept incoming connections from certain ip's i have two i need my mail server and the cuda. Hope i havent confused you all, any help or suggestions or answers to my questions would be appreciated. -- Tim Casten National Air Traffic Controllers Internet Services
