F5 and anti-spam
is there any policy in F5 that help me to filter mails and works as anti spam ? if yes then how can i configure it ? or it is require license ?
I don't think so. The only feature that can help a little is the ip intelligence as it will block bad source ip addresses from bad domains.

F5 had a MSM module but that was a long time ago:

Dear Nikoolayy1,
the ip intelligence is already activated and I'm looking for extra layer. thanks a lot.
many thanks i will check that.
If don't want to buy another device you may consider SMTP relay services like SendGrid etc. that are cloud based offerings. Symantec even has Email Security.cloud but from F5 point I think that they have given up on this market :
Also I just renembered that you can use the URLDB for the SWG module to filter based on FQDN/Domain names:

Still you will need to see if you can do this for the SMTP traffic and it will be hard work and maybe not worth the efford:
