Thanks Noel. The problem was surely in the logger. Postfix was working fine. My policy server implementation was also fine. It in fact seem to be a feature of the logger! I was so worried about it.
My implementation is Java based and I am reading the policy request key-value pairs into an instance of Properties class. Once loaded, I write to the log file using the 'list(PrintStream)' method of that class. I never knew that it summarizes the output. --- On Thu, 3/17/11, Noel Jones <njo...@megan.vbhcs.org> wrote: > From: Noel Jones <njo...@megan.vbhcs.org> > Subject: Re: SMTP Access Policy Delegation - issue with sender address > To: postfix-users@postfix.org > Date: Thursday, March 17, 2011, 12:57 AM > On 3/16/2011 1:27 PM, Kamal > Wickramanayake wrote: > > Hi, > > > > I have attempted implementing an access policy > delegation mechanism based on this document: > http://www.postfix.org/SMTPD_POLICY_README.html > > > > To test, I got the policy delegation requests logged > into a file.
