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.
| Callable function | Description |
|---|---|
| MQ_email() | Access to the underlying email address |
| MQ_local() | Check whether a recipient address is "local" |
| MQ_setLocal() | Mark a recipient as "local" |
