hello everyone.
I want to konw how to setup the Ticket Commands when I add a periodic task in the web interface of GenericAgent ,please show me some advices if you know how to use it . Thanks very much!!

ferrosti , jojo ,thanks for your help . I know how to find the answer now !!!

ok.I just want to learn if OTRS has this feature that agents can handle tickets through email. for example:I am an agent ,I want to close a ticket in OTRS ,so I send a mail to OTRS system ,when the system receive this mail ,it can change the ticket's state which i want to close. Am I clear ? Thanks ...

Thanks for your reply ! but use the mail filter only can handle the current ticket from the mail , I want to close the old ticket which existed in otrs before receiving this mail. Is it possible?

Can we handle the existed tickets in otrs (e. close the existed ticket in otrs) by sending email ? If this can be done, how ? Thanks for help !!!
