You are misunderstanding the process for creating a "virtual domain" in
DNS.
mail.spiderplant.net is currently a CNAME for bonsai.spiderplant.net.
This requires EVERY mail server out their to do the rewrite of the address
as you are currently seeing.
What you need to do is the following:
1. remove the CNAME record completely. It prevents you from doing the
setup correctly.
2. add an MX record for mail.spiderplant.net pointing at
bonsai.spiderplant.net.
BIND format:
mail.spiderplant.net. IN MX 10 bonsai.spiderplant.net.
3. add an A record for mail.spiderplant.net pointing to the IP address of
bonsai.spiderplant.net
BIND format:
mail.spiderplant.net. IN A 213.133.64.85
DONE. Do NOT add a PTR record. The PTR for 213.133.64.85 should point to
bonsai.spiderplant.net and ONLY bonsai.spiderplant.net.
This should fix your problem provided you have qmail set up correctly.
