[admin_2]

Hi all,

In attempt to put a stop on outgoing spam, I would like to know how to configure my pix515e to block port 25, any help would be appreciated,

thanks Jamie

you can configure an ACL something like this to block the smtp traffic:

access-list in_access_out permit tcp host 10.10.10.1 any eq 25

access-list in_access_out permit tcp host 10.10.10.2 any eq 25

access-list in_access_out deny tcp any any eq 25

access-list in_access_out permit ip any any

access-group in_access_out in interface inside
