I did make sure to do cpanm on all the modules in @INC and it said they're up to date. Please ignore the cast line that you've highlighted, that was added by me to try troubleshooting. The error however doesn't change with/without that line. Thanks for pointing Email::Stuffer, I will have a look.

However, there's an email notification system already running, which is configured same way as in the sample provided. The monk who coded that has left the firm and so I'm learning perl. Not really sure if I will have time rewire the system with Stuffer. Let me see.

Thanks!
