What is CVE-2006-4616?

The MailEnable SMTP service is vulnerable to a denial of service attack that can be triggered by a specially crafted SPF record. When the service attempts to perform lookups for a domain with numerous SPF records, it may result in a null pointer exception. This can lead to the service becoming unresponsive, effectively disrupting mail operations. This vulnerability affects several versions of MailEnable before the ME-10014 (20060904) patch, and users are advised to update their installations promptly to mitigate potential risks.
