IMAP Authentication Error - Target name and hostname missing

We're seeing a lot of the following IMAP/NTLM errors:

- IMAP NTLM; AuthenticateMessage; Target name and hostname missing 
- IMAP NtlmAuthenticate Login failed: NTLM; AuthenticateMessage; Target name and hostname missing.
 
This is a relatively new issue that we've seen over the last few months. 

What is the target name and hostname referring to?
