Problem while Sending emails

[Vemraju]

Hi,

I am using System.Net.Mail for sending mails. The emails are going out sometimes and not going out sometimes. When the mails are not going out it is giving the following error:
“Error in processing. The server response was: Greylisted, please try again later”

Why I am getting this error. My system is not having any firewalls.


Thanks in advance.

Hi Sundar,
Welcome to TDSN, I hope you like it here!

Sometimes SMTP servers are set up in such a way that prevents the Server from sending spam. If it decides that your program is spamming, you will get a response of this type. I would contact the company hosting the SMTP server and find out if they can help you out.

Cheers!
