[otrs] The Logging System

In modifying PostMaster.pm today to block a sender's address from importing email into the system I hit upon something that may or may not be a bug. It appears that the calls to $Self->{LogObject}->Log(Message='Message Here'); do not produce results. I had included code to block an address, basically copying the X-OTRS-ignore block and replacing it with the From parameter. I have verified that the code does indeed block the address, but I never see the message in the system logs. Am I missing something here? Does LogObject point to something different than the System Log? Charles
