Envelope and recipient addresses are wrapped in MQ_Address structures. You can get a reference to this structure by calling the MQ_envelope() or MQ_recipient() function on a MQ_Message structure, or by implementing the mq_smtp_in_mailfrom() or mq_smtp_in_rcptto() functions.
Once you have access to a MQ_Address struct, you can call the following functions on it to get access to the underlying address, and to other address properties.
|MQ_email()||Access to the underlying email address|
|MQ_local()||Check whether a recipient address is "local"|
|MQ_setLocal()||Mark a recipient as "local"|
