Hey guys, I already have an Mercury Server/Mercury SMTP Client(relay version) running in my network. I would like to use this server instead of adding an local email server. Is this possible? I changed my settings in the config.pm file, but that doesn't work. $Self->{'SendmailModule::Host'} = '192.168.201.1'; $Self->{'SendmailModule::Port'} = '25'; $Self->{'SendmailModule::AuthUser'} = 'test'; $Self->{'SendmailModule::AuthPassword'} = 'test'; I am always getting this error and I don't know what to do know. SMTP authentication failed! Enable debug for more info! Traceback (204): Module: Kernel::System::Email::SMTP::Send (v1.3.2.2) Line: 104 Module: Kernel::System::Email::Send (v1.1.2.1) Line: 52 Module: Kernel::System::Ticket::SendArticle::SendArticle (v1.11) Line: 180 Module: Kernel::Modules::AgentForward::SendEmail (v1.22) Line: 304 Module: Kernel::Modules::AgentForward::Run (v1.22) Line: 88 Module: ModPerl::ROOT::ModPerl::Registry::D_3a_otrs_otrs_bin_cgi_2dbin_index_2epl::handler (v) Line: 609 Module: (eval) (v1.58) Line: 184 Module: ModPerl::RegistryCooker::run (v1.58) Line: 184 Module: ModPerl::RegistryCooker::default_handler (v1.58) Line: 154 Module: ModPerl::Registry::handler (v1.99) Line: 16 I have Windows 2000 running and OTRS 1.1.3. I don't know really know where I can enable the debug function. Do I need to activate it to solve this problem? Did I forgot to change my settings somewhere else too? Thanks in Advance Andi Bublitz
