Hi. I am certain the issue we are experiencing is one that is very common. We have an internal spam filter [10.1.1.5] that receives all smtp traffic by being translated to 18.104.22.168 [obviously an example IP] on the Internet. Therefore, our public mail.acme.com is 22.214.171.124. Now, our mail server [10.1.1.10] send OUT mail on 126.96.36.199 [public]. The PROBLEM is that today, many firms are using reverse lookups when they receive an email. Thus, an email received from us has a source address 188.8.131.52 yet our 'SPF' record returns 184.108.40.206 for the lookup. The mail is droppeed. We need to have all smtp outbound mail 'look like' its source address is 220.127.116.11 EVEN THOUGH incoming traffic for 18.104.22.168 goes to the spam filter at 10.1.1.1. I hope that makes sense.... I've tried reversing the parameters in static translations to now avail... Please help.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
