No -- just so long as a reverse DNS entry exists, there is no problem with
Declude. There are a lot of mailservers that have virtual domains that are
all using the same IP address, so often the IP address does not
match. Note that the reverse DNS entry (ducts.com) should also have an A
record pointing back to the same IP (which ducts.com does), but Declude
does not check for that.

And that's your problem. Declude doesn't know (or care) where you *think*
the E-mail is coming from, it just cares where it really is coming
from. In this case, the E-mail was sent to IMail by
209.224.184.153. Perhaps their router is set up to "fix up" the SMTP
connection, and acts as a mailserver. In any case, that is where the
E-mail came from.
