    dear community,

    we have changed the public ip-address of our server to a internal (because we have a new setup with 1:1 port forwarding).
    since i have done this (has changed the ip-address from static to internal) the postfix server from our webs on same server are not receiving emails from that.

    what i have to change that this working correctly? before i have done this change, all working good.

    thank you so much

    In general, public mail and dns server must have static / fixed public ip unless they are only meant for internal usages, so the fact that you are using static / fixed local ip doesn't dismiss that requirement.

    Do provide further info as asked by @Th0m above.
