I have two different errors when receiving mail from this server mailserver.santanderrio.com.ar[].

postfix/smtpd[23015]: NOQUEUE: reject: RCPT from mailserver.santanderrio.com.ar[]: 554 5.7.1 XXX@XXX.com: Relay access denied; from=mensajesyavisos@mails.santanderrio.com.ar to=XXX@XXX.com proto=ESMTP helo=rs6.mails.bancorio.com.ar

postfix/smtpd[2948]: NOQUEUE: reject: RCPT from mailserver.santanderrio.com.ar[]: 450 4.7.1 XXX@XXX.com: Recipient address rejected: Policy Rejection- Please try later.; from=newsletter@mails.santanderrio.com.ar to=XXX@XXX.com proto=ESMTP helo=rs7.ar.bsch

Conf =

smtpd_recipient_restrictions = reject_unknown_sender_domain,
                            reject_rbl_client cbl.abuseat.org,
                            reject_rbl_client bl.spamcop.net,
                            reject_rbl_client sbl-xbl.spamhaus.org,
                            reject_rbl_client hostkarma.junkemailfilter.com=,
                            check_policy_service inet:

any ideas?

let me know if you need an additional data –  melocoton Jul 8 '10 at 2:52
I don't know anything about postfix but the first entry is a permanent failure and it looks like postfix doesn't know it's authorative for the domain of the intended recipient. The second entry is a transient (temporary) failure, maybe because of some problem with the recipient's mailbox. –  joeqwerty Jul 8 '10 at 3:02

The first error message is just what it says, an attempt to relay mail through your system was rejected. Another ServerFault question touches on this, and may be of use:

I was assuming that the recipient in the first entry was an internal recipient, but that may not be the case as you've stated. –  joeqwerty Jul 8 '10 at 3:17
