SMTP server port
-
I have a small app that emails me a message every morning. I recently had to change the SMTP port from 25 to 587 on our server due to spam. So I went into the code and changed the SmtpMail.SmtpServer = 192.168.1.15 to 192.168.1.15:587. I am getting this error: The server response was 421 Cannot connect to SMTP server 192.168.1.15 (192.168.1.15:25), connect error 10061. It seems it is still trying to access on port 25. I looked around a bit, but could not find anything on how to change the port it uses. I thought adding the port to the end of the IP address would be sufficient. Thanx in advance

Hi, Surprised to know that you are still using .Net framework 1.0 / 1.1. In v1.0 or v1.1 you need to set Fields property of MailMessage class's instance for changing default port like this --
objMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", NewServerPort)NewServerPort will be your port; in your case 587. Also objMessage is instance of MailMessage class. I will recommend you to use .Net 2.0 framework for sending mails, because it exposes appropriate properties for everything related to mails. There is a change in namespace and the new one is - System.Net.Mail. Hope this helps !

Thanx a lot! I am not an all day coder. I write little apps and scripts to help me out through the daily grind. I do the tech support work for a small business and my main job is keeping everything running smoothly and handling all the computer problems when they arise. I have .Net 2.0 installed, but how do I use it in VS2003?

Hi, I am afraid, but you cannot use .Net Studio 2003 for developing applications on framework 2.0. For that you will need VS.NET 2005 or VS.NET 2008. I think 2008 is a better choice since it can be used to develop applications that target all framework versions. Of course, the choice is yours (rather your company's) Hope this helps.

Thats what I thought. I installed VS2005 a while back, but it was buggy and a resource hog, so I uninstalled and stuck with 2003. I got a beta disk of VS2008 from MS last month, but have yet to play with it. What about with Monodevelop?
