Error in Postfix


#1

I’m having this problem in postfix:

Nov 17 21:01:50 servo2 postfix/smtp[25043]: F1E0530BBDA: to=trukulo@gmail.com, relay=mail.lluche.com[208.97.132.223]:587, delay=2.9, delays=0.06/0/1.6/1.3, dsn=4.3.5, status=deferred (host mail.lluche.com[208.97.132.223] said: 451 4.3.5 Server configuration problem (in reply to RCPT TO command))

Always says connection refused.

My main.cf in postfix is:

— BEGIN —

line of that file to be used as the name. The Debian default

is /etc/mailname.

#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

appending .domain is the MUA’s job.

append_dot_mydomain = no

Uncomment the next line to generate “delayed mail” warnings

#delay_warning_time = 4h

readme_directory = no

TLS parameters

smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_use_tls = no
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for

information on enabling SSL in the smtp client.

— END —

My smtp_pass is

— BEGIN —
[mail.lluche.com]:587 inf@lluche.com:xxx
— END —

I read wiki, and i read everything i can. It just don’t work.

May you help me?
