sendmail appending domain name to invalid lookups

Dear group,

Recently, I have noticed that sendmail is appending my domain name "domain.com" to the end of any unresolveable lookups.

For example, if sending a message to `foo@nonexistant.nowhere.com', once sendmail notices that this domain name is unresolveable, it will append `domain.com', to end up with: `foo@nonexistant.nowhere.com.domain.com'.

For various reasons that don't need explaining at this point, I have a wildcard DNS record for my domain, so that web traffic to *.domain.com wil be accepted.

I have also removed the `search domain.com' entry in my resolv.conf file, but the behaviour still manifests itself. For example:

> /usr/lib/sendmail -d8.20 -bt

ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>
> /canon nonexistant.nowhere.com
dns_getcanonname(nonexistant.nowhere.com, trymx=0)
dns_getcanonname: trying nonexistant.nowhere.com. (ANY)
        NO: errno=0, h_errno=1
dns_getcanonname: trying nonexistant.nowhere.com.domain.com (ANY)
        YES
dns_getcanonname: nonexistant.nowhere.com.domain.com
getcanonname(nonexistant.nowhere.com) returns nonexistant.nowhere.com.domain.com

Any ideas as to how I should fix this?
