SMTP relay
I have three SMTP servers to load balance and I want to create an iRule to restrict SMTP access at the F5 instead of having to maintain the relay list on all three servers. I have look at the codeshare but none of them really address this. Any help or guidance would be appreciated.
- Michael_YatesNimbostratusHi Russell,
when CLIENT_ACCEPTED { if { [class match [IP::client_addr] equals allowednetworks] } { pool matching.pool.name } }
- bman_12685Nimbostratusthe question i have for this , is how to test this? I have implemented a simliar ruleset along with first setting the smtp proxy, yet a manual test by telneting to port 25 is rejected as such im hesitant to put this rule into production.

- Richard__HarlanHistoric F5 AccountAny easy way to test instead of the reject command you can log if you would have rejected the traffic. If you keep the rules on the servers durning this time you should have a list of what the LTM would have rejected.
