http://serverfault.com – I'm working on a website, and I need to test the functionality of sending email messages from ASP.NET, something like this: Dim msg As New MailMessage("email1", "email2") msg.Subject = "Subject" msg.IsBodyHtml = True msg.Body = "Click here." Dim client As SmtpClient = New SmtpClient() client.Host = "My-Server" client.Port = 25 client.DeliveryMethod = SmtpDeliveryMethod.Network client.Send(msg) This is running from a Windows 8 workstation. I've installed SMTP server on my Windows Server 2012 machine. The mail shows up in the mailroot/Queue folder and sits there, eventually getting deposit (HowTos)

Stories similar to Trying to Set up SMTP Server on WIndows Server 2012

I have a Windows 2008 server that is running an SMTP server. The server has a public IP Address. I have 2 other windows servers, not in the same network, that are used for hosting client applications. We have a need to make sure that the emails sent through the client application to the SMTP server look like they originate from the original domains.

I've been looking through questions on Stackoverflow and Serverfault but haven't found the same problem mentioned - though that may be because I just don't know enough about how email works to understand that some of the questions are really the same as mine ... here's my situation:

I have a web application that uses .Net's SmtpClient to send email.

I'm trying to understand how all the components of a mail server fit together.

I understand that the SMTP server is necessary to send emails. In terms of accessing email, I'll setup a webmail client but do not need access through a desktop client.

So my question is: do I need an IMAP server in this case? or can the webmail client somehow link directly to the SMTP to send and read emails?

Client : Windows 7 x32 | Dell Latitude E6510, transferring to another identical machine over the network.. 120mbs.

Transferring to any server (2003 server, 2008, 2008R2, or VM's) I can not get more than 30MBS. The server is plugged into the same switch and is a physical server. I have jumbo frames and flow control enabled.

I'm trying to connect remotely from my Windows 8 client to manage my Hyper-V Server 2012.

We are in the process of setting up an OpenVPN server for some servers running in a cloud.

My script is about sending notfication email, and it was running well on my local machine, but when I removed it to an server 2k3, the email cannot be sent out with below error log:

Exception calling "Send" with "1" argument(s): "The SMTP server requires a secure connection or the client was not authenticated.

I'm having the strangest time getting a Thunderbird email client to connect to my Exchange 2003 server.

I got the incoming IMAP account set up no problem, and I can receive mail. However sending mail will not work no matter what SMTP settings I enter. After checking the server, the proper settings should be port 25 with no authentication or connection security, which I have entered.

I have a home broadband network which I also run an email server. As my provider won't give me a fixed ip address, and most servers refuse to accept smtp mail from dynamic ip ranges, I felt the simple solution we'd be to run a VPN between a virtual server I already have and my email box.

I've done that fine, I installed openvpn and that connection is fine.
