Public Property DnsServers As StringCollection

Visual Basic (Usage)	Copy Code
Dim instance As Smtp Dim value As StringCollection   instance.DnsServers = value   value = instance.DnsServers

public StringCollection DnsServers {get; set;}

public: __property StringCollection* get_DnsServers();
public: __property void set_DnsServers( 
   StringCollection* value
);

public:
property StringCollection^ DnsServers {
   StringCollection^ get();
   void set (    StringCollection^ value);
}

Property Value

Set the DnsServer property to a list of one or more DNS servers, and leave the Smtp.MailServer property empty to enable the sending of email messages directly to the recipient’s mail server.

This list is an ordered list; the first server will be attempted and if no response is received within the Smtp.DnsServerTimeout period, the next server in the list will be tried.

The system automatically populates the default DNS servers; you should only need to add to this list if the default DNS servers are not adequate.

If the message is being sent to many different recipient domains, the direct sending of messages can be many times slower than using a MailServer, since the Smtp control is now doing all the work normally done by a relay mail server.

Target Platforms: Microsoft .NET Framework 2.0
