Re: pop issue

[Luis Rodríguez <lmrc iss com mx>]

i have another question...

i can receive the mail, but when i try to send via the netscape email 
client the next error appears:

> An error occurred while sending mail. The mail server resoponded 5.7.1 
> <lmrc iss com mx>...
> Relaying denied. IP name possibly forged [IP from the Mail Client]
> Please check the message recipients and try again


the same thing with ProFTPd
i connect with the name host but appears the name of the dsl modem

i try to edit the /etc/hosts

something like this:

> #127.0.0.1              linux.internet linux localhost.localdomain 
> localhost
> 127.0.0.1       localhost midomain.org
> 10.0.0.29       mydoamin.org
> 10.0.0.29       anotherdomain.net

where 10.0.0.29 is a local IP address, i try with the public IP but not 
works anyway...

i think for this reason when i try to send message i receive an error, 
because i dont know where configure or if may be is not possible because 
the modem connection, or maybe i forget something,

thanks for any comment
