Management of the MTA Queue 

An overview of the e-mails still situated in the MTA queue may be found here. All of the e-mails that could not be delivered successfully at the first sending attempt are in this queue. All of the e-mails that are listed could not be delivered because of temporary faults. This corresponds to the 400s status codes in the SMTP protocol. How long and how often the MTS will attempt to deliver these e-mails is defined in the basic configuration (see 17.1.8, 17.1.10).
