"�ben" smtp server til test?

Wed, 14 Aug 2013 12:31:19 GMT

Hej.

Findes der stadig �bne smtp-servere ude p� det store internet? Jeg skal teste min applikation som er �ndret til, at kunne aflevere Credentials (alts� brugernavn / password) til en smtp-server, ved afsendelse af mails.

Problemet er, at jeg ikke har en som kr�ver brugernavn/password, men udelukkende en som tjekker p� hvilket dom�ne man sender fra.

S� findes der en test-smtp for udviklere et eller andet sted?

Send mail med .NET

Sun, 04 Mar 2012 13:06:35 GMT

Hej,

Jeg har et webhotel hos web10.dk, og jeg fors�ger at sende en mail. Det skal foreg� s�dan, at man trykker p� en knap hvorp� der st�r 'Send mail', og s� skal C#-delen, som i �vrigt er back-end, alts� i en .cs-fil for sig, s�rge for.

Dette er koden til at sende mailen:

CSharp kode

 public void OnSendMailClick(object sender, EventArgs e)
 {
     System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("smtp.m99.dk", 25);
     smtp.Send(
         "afsenders mail",
         "modtagers mail",
         "Hej min ven",
         "<b>Hej</b> <i><font color=red>Thomas</font></i><p>Dette er en test...</p>"
     );
 }

N�r jeg trykker p� Send mail-knappen (som er en <asputton> og ja, den har en OnClick="OnSendMailClick"), s� f�r jeg den klassiske asp.net-fejlside at se. Meddelelsen denne gang er:

Unable to read data from the transport connection: net_io_connectionclosed.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.IO.IOException: Unable to read data from the transport connection: net_io_connectionclosed.

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

<%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

Hotmail afviser mail

Mon, 16 May 2011 21:52:14 GMT

Jeg benytter CDO message til at sende beskeder til folk, f.eks. n�r de har tilmeldt sig til en skakturnering, s� f�r de en mail, der bekr�fter at deres tilmelding er registreret. Men der er det store problem at Hotmail afviser mailen, sammen med et kopi af den mail der skulle sendes f�r jeg en txt fil med denne besked:

Reporting-MTA: dns;server26m.serverpark.dk
Received-From-MTA: dns;kontor-vyqa4pe4
Arrival-Date: Mon, 16 May 2011 20:46:25 +0200

Diagnostic-Code: smtp;550 SC-001 Unfortunately, messages from 86.58.167.80 weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors.

Jeg har forg�ves ledt efter en l�sning p� problemet, er der nogen der kan hj�lpe??
