About filtering mail with mailq

[deconya]

Hi

Im new postfix and Im learning how to use. My first problem is about the
spam because in my server are incoming mails with my domain but using bad
adresses and making copy to the aol.com domain. Im making:

#postqueue -p | grep ' Feb ....@aol.com' | sed 's/*//' | awk '{print $1}'
>spam.txt

but not appears de ID. I need to filter to domins in different lines, for
exemple:

ID     -m...@mydomina.com
        -m...@aol.com

How I can make this?

Thanks && Best Regards
