It can take several hours for DNS changes to become effective. You can
# dig domain0.com
from domain1's toaster to see what it's getting.

The symptoms you've described sound more like the effect of graylisting. I'd look into that to see if this is what's happening. The smtp log on domain0 should be showing a message to that effect though.

What version of spamdyke do you have installed?
Did you use QTP to install it?
Please post your spamdyke.conf file.

Hello list,

I just installed a qmailtoaster on a site (domain0.com) and have started interacting via email with users on that site from my site (domain1.com). My messages are not received right away. When I check my queue they are in the qmail queue on domain1.com. When I dump the smtp log on domain0.com it gives this error: DENIED_SENDER_NO_MX (sender domain has no MX record) for my messages. Eventually the email is delivered, but why does spamdyke give this error when the email is initially sent and then deliver it later. If I put domain1.com ip address in the spamdyke whitelist_ip on domain0.com qmailtoaster, first time delivery is a success, but I’d rather find out what is wrong with my MX record and fix it. My server (domain1.com) is not the domain name server for my domain and I am unsure whether this is the problem. All the records, including MX is controlled by me at my domain registrar.
