Hello guys, I have a lot of problems with my sendmail, I can receive messages but I can't send, I always get a Relaying denied message, I checked a sendmail.org and old posts here in the forum, read all recomendations and this is what I did:

create a relay-domains file containing my domain puntos.org.ni
restart sendmail (It didn't work)

at sendmail.org says that I should add a PTR record in my DNS wiht my network addr . What is it?

Please, give me some help, I am workint around it about 2 days.

Here are my logs:

220 puntos.org.ni. ESMTP Sendmail 8.11.2/8.11.2; Sat, 3 Nov 2001 13:22:28 -0600
250 puntos.org.ni. Hello [192.168.0.2], pleased to meet you
250 2.1.0 diablo@infierno.com... Sender ok
550 5.7.1 baratous@yahoo.com... Relaying denied. IP name lookup failed [192.168.0.2]
Thanx,

take a look @ the file: /etc/mail/access

add the line: 192.168.0.2 relay

try that.

Your /etc/mail/relay-domains is supposed to look something like this, note the period at the end.

# Relay-Domains

192.168.0.
