[Dovecot] sieve

Hi, I'd like to keep all emails coming from alom-alert@anydomain and not forward those but rest of the emails will be kept and forwarded as well.

I put following in the .dovecot.sieve

if header :contains "Sender" "alom-alert@" { keep; if not header :contains "Sender" "alom-alert@" { redirect "my@emailid on server"; redirect "xyz@gmail.com"; redirect "abc@tbc.edu"; stop; } }

Is this correct?

Thanks, UG
