Actually it is very simple to do.
First confirm if procmail package is installed. If not install it from cd.
suppose you are recieving mails for cv and jobs etc.
we will consider that in the Subject fieldthere are words like, Application for, CV, jobs etc,
so create a .procmailrc file in your home directory.
create filter like
:0c
* ^Subject:.*\<jobs for the post of\>
!
abc@example.com
Above filter will forward all mails which contains "jobs for the post of" in the subject line, to the email
abc@example.com with keeping a copy to you.
You can change subject statement inthe filter with probable subject line.
It searches for the words in the subject line though the actual subject line is very long.
please let me know if it works for you.
