hi i've just set up an exchange server. the link to my initial issues are below. please read first for background.
now i can send internally, i can recieve externally but get relay error when sending externally. 5.7.1 relay permission error.
i have tried adding my ip range to the relay permission, no luck.
i also noticed in my queues that i have a queue of server 1 (old server) could this be causing any problems (refer to previous post)
please help and also help me make this a secure exchange so i dont get bombarded with spammers using my mail server and then i get blacklisted.
