We have a user who is on POP3 and he really does not want to change anything he currently has. We have installed exchange 2003 with OWA and everything works great.
i understand that ISP's block port 25 and i understand why, but what can i do for this user who would like to stay pop3 and be able to send mail. is there a relay server i can use? pay for? anything other then using OWA?
