hello all thanks for mailing and solving my problem especially cory wright who give me idea. but i need some more flexible. i want that anybody can access mail from anywhere either from outlook or some client. Then i need a general rule from anywhere mail will be sent. as now i write in tcp.smtp 127.0.0.:allow,RELAYCLIENT 198.101.100.1:allow,RELAYCLIENT for example anyperson who is any other state and configure outlook ,in that case he can't mail sent bcz it give error of invalid rcpthost. so i need a global ,from anywhere i mail sent.no need to add address or ip of in tcp.smtp. thanks
zafar
