SMTP sever

Anand MR

Hi friends,

Here is my code for sending mail to Multiple users at a time.Its working fine.

But for example in multiple user's email id's any one is invalid ,in this case mail is not send to the rest of the valid email also.

My expectation is mail should send if there is valid email id's in the To address even any one of the email id is invalid.

Please give me the solution for this as soon as possible friends.

SmtpClient client = new SmtpClient(); //SMTP Client to Configure & Send email

client.Host = "";

client.Port = "";

client.Credentials = new System.Net.NetworkCredential("", "");

client.EnableSsl = false;

email.Subject = dsInitialdata.Tables[1].Rows[0]["EMAIL_SNT_MSG_SUBJ_TXT"].ToString();

string[] toArray = {"[email protected]","[email protected]","[email protected]"};

if (toArray != null && toArray.Length > 0)

{

foreach (string toId in toArray)

{

if (toId.Trim() != String.Empty)

{

email.To.Add(toId);

}

email.IsBodyHtml = true;

MailAddress from = new MailAddress("[email protected]","Welcome");

client.Send(email);

Hi Bro,
I got the solution for this issue.
our company domain not allowing to send mail to external domain like [email protected],[email protected]

[email protected], [email protected] - will fail
[email protected], [email protected] - will send

Thanks

Hi,

I am not sure why are not receiving mail for valid mail. Try to check in debug mode and addtional you can add try ,catch blocks like in below code

if (toArray != null && toArray.Length > 0)
{
foreach (string toId in toArray)
{
if (toId.Trim() != String.Empty)
{
try
{
email.To.Add(toId);
email.IsBodyHtml = true;
MailAddress from = new MailAddress("[email protected]", "Welcome");
client.Send(email);
}
catch(Exception ex)
{
Response.Write(ex.Message);
}
}
}
}

Here Please check what is exception ?

Hi Bro thanks,

NetworkCredential /SmtpClient Correct
bcoz i am receiving mail while paasing valid email ids like
"[email protected],[email protected]"

Suppose "[email protected],[email protected],[email protected]" here second one is invalid .This is case rest of the two valid emails ( "[email protected],[email protected]") not receiving mail.

SMTP is working fine.

You are welcome,
Here two emails first one "[email protected]" ,second one "[email protected]",
here the second one is invalid it not registered in gmail domail, In this scenario this [email protected] valid email but not receiving the mail right ?

First check NetworkCredential /SmtpClient Correct or not.

If all are correct NetworkCredential /SmtpClient and valid email then you will get mail Pleae check it your end.

Hi Bro Thanks for you,

You made changes like below in my code.Basically always To address will come with any email id.It wont be null or empty.

In my case
[email protected],[email protected] , here the second one is invalid it not registered in gmail domail, In this scenario this [email protected] valid email also not receiving the mail ..This is my problem

if (toId.Trim() != String.Empty)
{
email.To.Add(toId);
email.IsBodyHtml = true;
MailAddress from = new MailAddress("[email protected]","Welcome");
client.Send(email);
}
}

Hi Anand,

Try this

SmtpClient client = new SmtpClient(); //SMTP Client to Configure & Send email
client.Host = "";
client.Port = "";
client.Credentials = new System.Net.NetworkCredential("", "");
client.EnableSsl = false;
email.Subject = dsInitialdata.Tables[1].Rows[0]["EMAIL_SNT_MSG_SUBJ_TXT"].ToString();
string[] toArray = {"[email protected]","[email protected]","[email protected]"};
if (toArray != null && toArray.Length > 0)
{
foreach (string toId in toArray)
{
if (toId.Trim() != String.Empty)
{
email.To.Add(toId);
email.IsBodyHtml = true;
MailAddress from = new MailAddress("[email protected]","Welcome");
client.Send(email);
}
}
}
