how to set my mail server a relay
Posted on 2008-10-15
i have an exchage server 2003 SP2 in my LAN.ither is a script on my oracle database that sends mails to our company staff.this script is working fine for all internal mails (in my domain) but it is not sending mails for mails outside my domain ex hotmail,yahoo, gmail,....(because i have several users..physicians mainly that check their external mails only ,and i need to send them these mails)
when i tried on one mail for testing purposes, i got this message:
ORA-29279: SMTP permanent error: 550 5.7.1 Unable to relay for firstname.lastname@example.org
how can i fix this issue without removing securiiy from my mail sevrer and not transforming it to open realy server???
