I have an application, which sends email to multiple users with different email body for each user.
I am calling the following function in a loop:
On an average, the program sends around 25 emails and all emails are delivered successfully, without any delay. But the LAN administrator complained that my program is sending a large number of UDP packets to all the users on the LAN, and thus clogging the network.
Any idea what could be the possible reason for this? It's strange since all the emails are received without any issues. Any way to make this program more efficient?
