Unoeuro / C# / Umbraco SMTP problem

Hello all,

I know this is more like a c#/unoeuro problem but i will try anyway.

When i try to send email from my page nothing happens, it works fine on localhost but not on unoeuro. Here is my code:

 var smtpServer = new SmtpClient("asmtp.unoeuro.com", 587)
        {
            Credentials = new NetworkCredential("----", "----"),
            EnableSsl = true
        };

        try
        {
            MailAddress from = new MailAddress("------");
            MailAddress to = new MailAddress("------");

            MailMessage mailMessage = new MailMessage(from, to);

            mailMessage.Subject = ""          
            mailMessage.IsBodyHtml = true;
            mailMessage.Body = ""
            mailMessage.ReplyToList.Add(---);
            smtpServer.Send(mailMessage);
        }
        catch (Exception)
        {
            throw;          
        }

    }

Earlier today I got this error:

Transaction failed. The server response was: 5.7.1 <nt34.unoeuro.com[93.191.156.17]>: Client host rejected: Relay from servers and automated mails are not allowed, use smtp.unoeuro.com instead - For help see https://unoeuro.com/support/?s=asmtp.unoeuro.com

But i still can't find any solution, I have tried to change it from asmtp to smtp but with no luck.

Hope someone has an idea of a solution :)

Hi Henrik

You need to use port 587 when using smtp.unoeuro.com. https://en.unoeuro.com/support/faq/mail/606/
```
  <system.net>
    <mailSettings>
      <smtp from="[email protected]">
        <network host="smtp.unoeuro.com" port="587" enableSsl="true" />
      </smtp>
    </mailSettings>
  </system.net>
```

Hi Søren

Thanks for the advice, I have now tried to add the following to my web.config:
```
<mailSettings>
<smtp from="---@---">
    <network host="smtp.unoeuro.com" port="587" enableSsl="true" userName="--@--" password="--" />
  </smtp>
</mailSettings> 
```
And that does not help :/

Have you also changed var smtpServer = new SmtpClient("asmtp.unoeuro.com", 587)

To var smtpServer = new SmtpClient("smtp.unoeuro.com", 587)
