    Is this a common technique to use a different FROM domain on top of a domain that is different for the RDNS? I imagine that ESPs use this technique?

    Only sending domains should have proper rDNS (mandatory mainly for GI mailing though). And you can use whatever domain you like in "From" and "Reply-To".

    It is common for the hostname of the envelope address to match the reverse dns hostname of the sending IP address.
    Some ESPs that maintain separate IP addresses for clients will usually have the hostname of the envelope address match the reverse dns of the IP address.
    Others with a shared IP infrastructure will have the rDNS hostnames under whatever domain they mail from.
    Something most people seem to forget is that ESPs "warm up" IP addresses and sending domains.
    The ESP is sending mail to people that are expecting it. The ESPs slowly ramp up the volume while building reputation.
    No amount of attempting to appear like an ESP will matter if you are sending mail to people that react negatively to it and you do not have a "warm up" process in place.

    Sending domains do not have reverse dns. A reverse DNS record is for the IP address.
    https://en.wikipedia.org/wiki/Reverse_DNS_lookup
    Reverse DNS is not "mandatory" for mailing GI.
    You will see a higher amount of rejections if you're attempting to mail from an IP without reverse dns configured though.
