I’m trying to understand how RT outbound and inbound mail works.
First question, if I don’t want inbound email to work, do I need to configure anything regarding sendmail or mail gateway? But I do need RT to send email notifications about new tickets, reminders, etc.
What tool does RT use to send email notifications like on ticket create/update etc. I installed RT 4.4.3 on centos 7 and these notifications work out of the box. I didn’t have to configure any sendmail or postfix or whatever. What does RT use to send those emails?
But when I tried setting up a cronjob to send reminder notifications 2 hours before the reminder is due, it does not work. My cron works, I tested it. So does it need the sendmail or whatever configured? Then why are the ticket notifications work?
And if I do need inbound email to work, is there a step by step guide to configure it? There is so much documentation and all is so scattered it’s so difficult to gather all together when you’re not a linux administrator. I need to set it up to work with my gmail account.
