Answer
GMS Anti-Spam has run a Mail Meta Language (MML) script which has requested that this message should be rejected. All messages that pass through GMS may be processed by one or more MML scripts at this stage. Each script can cause the message to be delayed, rejected or continue through the normal delivery route. MML is a very powerful language that allows all sorts of changes and manipulation of the mail messages, for example: special headers can be added, attachments deleted, messages can be copied, etc. This MML script is specific for this domain and is typically used by GMS to implement per domain anti-spam functions, message filtering, etc.
In this case, session Undefined was receiving a message from Undefined apparently from Undefined to the account Undefined. The MML script at Undefined requested that this message be rejected with
Undefined
If the MML script should not have prevented the message being delivered, you will need to identify what created the script and check the configuration. A range of scripts are available in Gordano’s Knowledge Base.
Please note that Gordano do not support user scripts.
