Monitor a file and send mail
I want to monitor the maillog file in real time and send a mail when a certain grep condition is met. Every time the grep condition is met a mail will be sent. I wish to ignore all grep conditions 30 mins after each mail and thereafter continue monitoring.

For example:
  1. Condition is met, mail is sent
  2. 30 mins no mail even if condition is met.
  3. After 30 mins again condition is met and a mail is triggered.
  4. Again for next 30 mins no mail even if condition is met.

and so on.

I am doing the following:

Code:
tail -F -n0 /var/log/maillog | \
 grep -v --line-buffered 'status=sent' | \
 grep --line-buffered -v 'relay=local' | \
 grep --line-buffered 'relay=' | \
 while read line
 do
    echo "$line" | \
    mail -s Test mail@group.com
 done

Now i am not sure how to prevent mail sending 30 mins after the event is triggered.
