Hi , I have searched the mail list , as well as googled it provusely yet there are no clear indication as to what the solution is : We have been getting this error , at various intervals when trying to reply to tickets : [Mon Oct 23 10:11:10 2006][Error][Kernel::System::Email::SMTP::Send][97] Can't send to: [EMAIL ADDRESS]! Enable debug for more info! This seems to be intermittent , as I cannot see a clear defined criteria for this error. Please , please any help is appreciated as I am at a loss at the moment. Regards Daniel
