Question

i have a win server 2003 with 3 ips , i am making a program that sends a bulk mails , but i`d like to switch between the 3 ips while sending emails , say for example , first mail sent using first ip and second mail using second ip and third mail using third ip , i know how to send mails using C# , but is there any class that chooses switch ip or something , i am actually not expecting codes , i want any idea so i can start digging .

Answer 1

3 IPs are not enough. Do you have 3 Mailservers using the 3 ips ? If yes it is possible.

I would use Random…

Random r = new Random();
int mailServer = r.Next(1, 3);
SmtpClient client;

if (mailServer == 1) client = new SmtpClient("mail1.yourdomain.com");
else if (mailServer == 2) client = new SmtpClient("mail2.yourdomain.com");
else client = new SmtpClient("mail3.yourdomain.com");

client.Send(...);
