SMTP newbie queries: #< #5.3.5 SMTP; 553 5.3.5 system config error> #SMTP#
We are using the sendmail in a Solaris 10 with kernel 150400-13 server to perform SMTP relay. Version of sendmail is Version 8.14.5+Sun.
There is a error encountered. The sender recv the following:
The recipient e-mail system can't process this message now. Please try resending the message later.
Diagnostic information for administrators:
Generating server: <SMTP relay>
#< #5.3.5 SMTP; 553 5.3.5 system config error> #SMTP#
Original message headers:
Return-Path: <sender address>
Received: from <SMTP relay>
Any pointer is appreciated. Thanks in advance.
