Hello all, I'm looking at a client's site and they have unprotected access to port 25 (i.e. I can telnet to it and issue commands). When I attempt to send an email I get this message '553 Relaying is not supported'. My question is
Yes, funny eh ? Relaying is not allowed to prevent spam. Contact the postmaster of this system, to allow it for your hosts or for special domaines.
two-fold: 1)What could I do with the unprotected SMTP access if I can't send mail. 2)What purpose do you believe that the SMTP service provides? Does the SMTP simply recieve!?!? Thank you all, Zach
Receiving will be allowed for all domaines, this server is responsible for. Regards Hans-J. Ullrich
