What is the host name? I want to send emails using Exchange Online which I think the host is "red001.mail.microsoftonline.com"?
I'm needing to send around 500-2500 emails out at a time to internal email accounts. I'm wondering which was would be faster both for the mail server and for my client app. Should I send multiple emails with just different TO addresses, or just one with multiple BCC addresses? I tried testing this by sending a bunch to my own email and the multiple emails method work, but with the BCC and a single message I only get that single message in my inbox. Shouldn't I be getting as many copies as the number of times I put my address in the BCC line?
View 1 RepliesI run a Exchange 2010 server and created an account for one of my websites to send e-mails.
The webserver's IP is even listed on the [Organization Configuration] -> [Hub Transport] -> [Global Settings] -> [Transport Settings] -> [Message Delivery] list.
The code sets a set of Network Credentials, but setting incorrect or correct settings, it doesn't matter; if I list external e-mail addresses, I get a "Mailbox unavailable. The server response was: 5.7.1 Unable to relay for <address>" message, 'local' addresses that are cc-ed, do get delivered...
When checking with telnet, I noticed that the only AUTH option was AUTH NTLM, but when checking the NetworkCredentails, it stated that NTLM should would.
Learning how to do a master page in asp.net. Trying to figure out how my style sheet interacts with respects to the master page and content page. I can get HTML tags like body and the style sheet to react. But when I call the ID attribute of a label no styling takes place. What am I missing here as far as interaction? BTW I'm using VS2008
CSS sample:
body
{
height:1200px;
width:920px;
border-style:solid;
border-color:blue;
padding:10px 10px 10px 10px;
}
#toptext1
{
position:relative;
top:-225px;
right:-500px;
font-size:22px;
font-weight:bold;
}
From the master page:
<body>
<form id="form1" runat="server">
<asp:image id="cookNookLogo" ImageUrl="images/Logo.gif" runat="server"
AlternateText="CookNook" Width="449px"></asp:image>
<p>
<asp:Label ID="toptext1" runat="server" Text="Quality Recipes, Hints and Supplies"></asp:Label>
</p>
From the content page:
<%@ Page Language="C#" MasterPageFile="~/CNMasterPage.master" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
<link href="App_Themes/cn/cn.css" rel="stylesheet" type="text/css" />
</asp:Content>
When I was doing this without a master page it worked so where am I going wrong with the attributes?
i am trying to send email using simple SMTPClient class, as the following code:

when i put the To email to be an Gmail,yahoo, hotmail email "as in example" or another domain.com email, the code is working with no issue, but when i put the recepient email to be any of Google Apps Emails, unfortunately the email didnot received. does the SmtpClient have a problem with google apps?
Inside my ASP.NET application, I would like to add an iframe where I can display the emails from our exchange server for the logged in user. The web application uses forms authentication with custom authentication (passwords are hashed and stored in db).
Is there a way to show OWA within my web app without prompting the user for password (OWA uses windows authentication)? Can I use impersonation in some fashion or establish a trust between my IIS server and the server running OWA?

I am developing an email form to my users to send email to vendors with an attachment. The aspx page is quite simple -- 2 dropdownlists, a fileupload control, and a send email button. They select their store (which populates the "From" address of the email). They select the Vendor (which populates the "To" address of the email). Then they browse for the file attachment and click "send email"
I just can't get outside emails to send. I do not get any error messages in the web page. If I change the email1 and email2 in SQL Server Vendor table to an email address (mine) within the domain I get the emails. However when I change to a test hotmail, yahoo, or gmail accounts the emails never get there. I have absolutely no confidence that my programming is correct so before I go to the IT Manager again I really need to verify I am not missing something on my end. We did make a change on the exchange server to allow anonymous email from my webserver and still didn't work.
Here is my webconfig file:

Here is my code-behind:

I have been playing around with the programming for 2 days making 1 change at a time then testing to see if external email is sending. I'm going quite crazy at this point ...
I've put in breakpoints and debugged. Below is the output from the latest test. I have concerns about the clientDomain being "SQLSVR" which is my webserver name, our domain is "chuckanddons.com". As well as the line "Domain" that is blank " " under NetworkCredential. Also the line TargetName "SMTPSVC/exchangesvr"

I am trying to send attachment mails in asp.net pages using SmtpClient Send() method.
It is working fine with 2mb files. When i tried with 7mb attachment file, it is saying:
"Failure sending mail."
What is the max size for sending mail using SmtpClient.Send(message) method.
Why the above error coming.....?
My site sends confirmation emails from a purchase. 95% of the time, it works. The other 5% after clicking the 'Confirm' button that runs the payment and should send the email, i get the following exception:
Details:
Exception: Failure sending mail.
Inner Exception: Unable to connect to the remote server
Inner Exception(2): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 72.167.234.197:25
The code to send the email is this:
Dim smtpClientPayPalSuccess As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient()
smtpClientPayPalSuccess.Host = "relay-hosting.secureserver.net"
smtpClientPayPalSuccess.Send(mailMessagePayPalSuccess)
FYI: I have confirmed with the hosting that I don't need any credentials, or a different port number than 25. This is also running over https. why this would be happening only a small percentage of the time?
I have developed an enterprise application in ASP.NET that sends emails using localhost SMTP server on the same box as the IIS web server for the ASP.NET app.
So right now any email sent from this ASP.NET app would hit internet firewall of the enterprise and then be directed to the right destination email address.
I was hoping to not hit the internet firewall of the enterprise, but hit the Exchange Server of the enterprise.
So the situation I am aiming for is: ASP.NET APP ===> Localhost SMTP SERVER ===>EXCHANGE SEVER 2003 ===>SEND OUT THE EMAIL
rather than ASP.NET APP ===> Localhost SMTP SERVER ===>SEND OUT THE EMAIL
So I still want to use the same mail configuration in my ASP.NET app of localhost as SMTP server, but just want the email to first go through Exchange Server before being sent out.
I know how to send emails, but is it possible to send out text messages?
View 8 RepliesWe have a series of sites that run in on an outside server but currently to send email everything is routing through our local inhouse exchange server. We are looking to move our exchange to a ofsite exchange service, but don't want the emails from our apps to route to it for sending. I have seen some third party add ons that will allow you to send email with the smtp but not route through exchange. Does anyone have any experience with doing this? If so what would you suggest. Just looking for a way that we can send mail with out routing back through our servers.

I recently learnt of a method to display binary images, from a sql table, that requires that the image's ImageUrl be a url of a second page with a querystring value. For example, if I have two pages, Page1 and Page2, If my image is on Page1, the imageUrl would be something like page2.aspx?ImgID= ImageID(The Querystring value passed to Page2 from Page1) . This method displays the image perfectly in the local host but then only the red X icon, that replaces a missing image, shows up when I run my application online.
Why are the images not displaying and how may I correct this? I have my codes below.
Image on Page1:

If I want to send an e-mail (up to 30) in response to user's action, what execution context do I do it from?
Do I do a sync call (mail server is in the same data center, so actual sending is fast)? Do I spawn a thread and send it from there? such that each user-request-to-send mail gets handled by a new thread? Do I have a background thread that handles a queue of e-mails?
The biggest issue I think, is that it is a shared web hosting. So I don't know what's a good way to install/start a windows service, or start a dedicated thread.
Details: ASP.NET MVC app, hosted on IIS 7.0 integrated mode, on discountasp.net using discauntasp.net smtp server.
Is there a better way? What's a "standard" way to accomplish this?
I need to send emails to users from my application at regular intervals.
Condition is: When a user registers to my site a confirmation mail will be send to the user. I have already done it. And if the user doesn't confirm the registration within 12 hours through that confirmaton mail the application must have to send a new confirmation mail to the same user and this should repeat for every next 12 hours until that user confirm the registration.
My Problem: When a user registers a new timer should have to be created for that user for sending emails in intervals of 12 hours. The email sending time for each user is based on his registration time. So we cannot use a common timer for sending mail to users.
