We are still experiencing some very annoying behavior after moving to a new SMTP account. Agent Notifications from the Agent site and email ticket replies from the Agent Site go through perfectly. All the automatic notifications fail. The otrs log says: [Fri Aug 4 09:40:13 2006][Error][Kernel::System::Email::SMTP::Send][100] Can't send mail to: xxx@xxx.com! Enable debug for more info! I tried adding the code below to enable debug, to no avail, same error message either way. I tried both $Self->{SMTPDebug} = 1; and $Self->{SMTPDebug} = 0;, restarting otrs between each test to the same result. # debug $Self->{Debug} = $Param{Debug} || 0; if ($Self->{Debug} > 2) { # shown on STDERR $Self->{SMTPDebug} = 1; } # added by Keith $Self->{SMTPDebug} = 1; So how do you enable debug? Do debug results even show up in otrs.log? Is it perhaps in a PERL or Apache error log instead. We are running this on a windows server. Any help, pointers, or other information deeply apreciated.
