I tried to send an email using the following code:
MailMessage message = new MailMessage();
message.From = new MailAddress(fromMailAddress.Trim());
message.To.Add(new MailAddress(toMailAddress.Trim()));
message.Subject = subject;
message.Body = body;
message.SubjectEncoding = System.Text.Encoding.UTF8;
message.BodyEncoding = System.Text.Encoding.UTF8;
SmtpClient client = new SmtpClient();
try
{
client.Send(message);
}
catch(Exception e)
{
throw e;
}
However, I got the exception:
The server response was: 5.5.4 Invalid Address
The from email, to email, server host name and port are all correct. The exact same code, with exact same input values works on another machine in our office
