Hi,

All I can see in the log snippet is a failure to authenticate using the mailbox name "christian". Ensure that the mailbox "christian" is hosted under a postoffice that is set to be the default post office within MailEnable. If the mailbox does not reside under the default postoffice then you will need to use the full mailboxname@postofficename format when specifying the username in your email client for authentication.

You can check the default post office setting under the "Localhost" properties.

You might also want to consider upgrading MailEnable to version 9.75 as it contains many fixes to MailEnable core services you need to apply since you are running 9.16.
