Relaying Denied

[Donald Clouse]

Hello All, I have qpopper running on a RH 8.0 linux box. When one of the pop3 users comes into the box to check their email they get the message:   Server:  IP Address Port 25 SMTP Server error 550 5.7.1 Relaying Denied Secure SSL Server error 550 Err 0x800cc79   Any Ideas on why a user on the box would be denied the sending of any outgoing email?   Thank You.   Don
