Why do blank MAI files appear in the outgoing mail queues?


Blank message files that sit in the MailEnable queues or get delivered to an end user may be caused by the means detailed below.


Blank or zero file sized MAI files can be created in the MailEnable outgoing queues by the delivery of a message between MailEnable connectors by the MailEnable Transfer Agent (MTA). If zero byte sized messages are appearing in the MailEnable queues, the issue usually points to a real time antivirus agent preventing the messages from being written to the disk.

If real time antivirus is running, then it is imperative that the MailEnable queues are restricted from protection or the resident scanner is disabled.

Another way the blank files could be created is by an MTA Pickup Event. Ensure that the same issue is occurring without a pickup event running in the MTA to troubleshoot any blank messages being created.
