You could use a postmaster filter or look at viewtopic.php?f=60&t=6586

i already filter the mails. I just need the notification, I want to notify the sender that his/her request ticket is a valid or invalid.

Send bad tickets to a queue with appropriate auto response, followed by generic agent delete tickets in bad ticket queue.

im sorry please elaborate.
I use this setting in post master filter
Postmaster Filter:

* Stop after match: No

Filter Condition
Header 1:Subject
Value 1: ^((?!(TSC-CAB\sACTIVITY\sREQUEST)).)*$

Set Email Headers
Header 1:X-OTRS-Ignore
Value 1: True

it ignores ticket with invalid subject format. now, I want to notify the sender that his/her ticket request has been created (if his/her request is with a valid subject format) and his/her request is invalid (if his/her request is with an invalid format).
I want the auto reply. Please help me..
This is so much appreciated. thank you

Don't ignore it. Send it to its own queue that has an autoresponse that says, "Your ticket has been rejected."
