I have a Postfix SMTP server setup on a debian Linux Distro.
Today, we are having an error occuring with our pop3 server and a lot of email is being deferred.
Because of that, Postfix is producing a new message in my mail.log file :
postfix/bounce: warning: [built-in]: zero result in delay template conversion of parameter "delay_warning_time_hours"
postfix/bounce: warning: please please reduce time unit "hours" of "delay_warning_time_hours" in delay templatereduce time
postfix/bounce: warning: for instructions see the bounce(5) manual
What does that meen exactly ? I've read Bounce(5) manual and they are talkign about a PostFix Parameter called : Bounce_Template_File where I can define that "delay_warning_time_hours" param, but I've never changed its value and it still got the default value i.e nothing.
Even if I had something or I was adding something, I don't even know why I should to do it.
Anyone could help me understand ?
