Occurs in direct send mode after the component finished DNS MX lookup of SMTP MX servers of recipients domains.

Event Data

The event handler receives an argument of type SmtpMessageMXLookupDoneEventArgs containing data related to this event. The following SmtpMessageMXLookupDoneEventArgs properties provide information specific to this event.

Remarks

If the message is sent without SMTP relay server directly to MX servers of recipient domains, the component must first discover these servers by performing MX lookup queries to DNS servers. Once this process is finished, the component raises MessageMXLookupDone and starts submitting the mail message to the discovered MX servers.

Example

This sample sends a message in direct send mode to 3 recipients on 2 domains. MessageMXLookupDone event is raised 1 time.
