The query to webmail.company.com is resolving to "webmail.company.com.domainname.domain" due to the search suffix being appended. Try placing a period after webmail.company.com to eliminate nslookup from suffixing the Search Suffix.

Was an additional search suffix set in the machine's NIC propertiers (IP properties, Advanced, DNS tab)?
