I have this web application (LAN) that sends an email when users registers to one of our events.
The code is pretty straightforward:
[code]....
The application sends the email without problems. The issue is that somehow a third person is enlisted in the cc, and receives a copy of the email!. What could be the problem? The smtp? IIS?
I can find loads of posts about codes to send emails using smtp, but I've got a problem. I want to send a registration mail to a user that has made a new account on my site, so he can activate it by clicking on a link in the mail. Only problem is: I need to use an smtpserver but I don't know which smtpserver i can use, so the mail is never sent!

This is my code below:

TL;DR - Any webapp devs out there able to squeeze performance out of using gmail as SMTP server without a 3-10 minute delay to delivery?I'm looking for some feedback from developers who are using gmail as a secure SMTP server for use with Webapps.Within the past 2 weeks, my company has switched to gmail to host email for our domains.I have a few webapps that send from our ISP server, but I'd like to refactor the code to use gmail with our domain name. I know the ISP can rig things up, but I don't want relay issues.I have gmail sending for the Webapps and it's more or less working. On ASP/IIS, I'm using SSL and on PHP Linux, I'm using TLS.It seems that TLS (port 587) works better than plain old SSL (port 465), but the overall performance difference seems minimal.What concerns me is that there is often a significant delay (10-20 minutes at times) to get email to a recipient no matter which method I use to send via gmail.While I understand this can happen in any environment, I am used to fast delivery. Use case is salespeople talking to customers and needing to get email to them very quickly using the Webapp. Before the gmail switch, usually less than a minute to deliver. Now, it is 3-4 minutes minimum.Am I crazy to try to use gmail for this purpose? There seem to be a lot of devs using it, so just wanting to know how it works out for them/you.
View 3 RepliesI am trying to send email from my asp .net code ,it is sending email to email ids except gmail.com. all mails with gmail.com is going into my Badmail folder in inet pub folder in my local system.
SmtpClient client = new SmtpClient();
client.Host = "mail.abc.com";
client.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
client.Credentials = new System.Net.NetworkCredential("ab", "rr");
client.Port = 25;
string to = "arvind.abes@gmail.com";
string from = "rvsales@westrvwholesaler.com";
MailMessage mail = new MailMessage(from, to);
mail.Subject = "hello......?";
mail.IsBodyHtml = true;
mail.Body = "hi, how are you?may be this will work";
mail.Priority = MailPriority.High;
//client.EnableSsl = true;
try
{
client.Send(mail);
}
catch (Exception ex)
{
Exception ex2 = ex;
string errorMessage = string.Empty;
while (ex2 != null)
{
errorMessage += ex2.ToString();
ex2 = ex2.InnerException;
}
Response.Write(ex2.Message);
}
mail.Dispose();
I've written a simple webservice and am running it locally to test it out. Right now, my settings are as follows:
From [URL]
Settings When Hosted Externally
<system.net>
<mailSettings>
<smtp from="noreply@domain.net">
<network host="smtpout.secureserver.net" password="<password>" port="25" userName="noreply@domain.net"/>
</smtp>
</mailSettings>
</system.net>
I've tried these settings, and also tried explicitly setting the properties of my SmtpClient object @ run-time. On send, I receive the following exception
"Failure sending mail. Unable to connect to the remote server - 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 64.202.165.58:25"

View 5 Repliesi have an aspx page, that takes in user data (name, number & email) after that information gets submitted to me, I need to send an email to their input email, with a message of confirmation.
View 1 Repliesi use the CreateUserWizard in order to create users. Asp.net generates automatically a password which is sent to the user by email.
The emailaddress must be like this: firstname.name@ourdomain.be . If 'firstname.name' doesn't exist in our Exchange server ('ourdomain.be'), then:
1) the user is still created
2) the message page with: 'Mailbox unavailable. The server response was: 5.1.1 User unknown' appears
E.g: if user John Wayne introduces by error Jhn.Wayne@ourdomain.be , then this user must not be created, and only a simple Alert-message must appear.
I tried a lot of Try / Catch / Endtry but all my attempts fail: the user is always created and the whole message page appears. I also tried with CreateUserWizard1_SendMailError sub.1

I was wondering if someone can direct me to a good quality tutorial on the process of registering and sending an activation link to the user's email address. I can't seem to find any useful tutorials online!
I have 2 pages, one is HTML and the other is ASPX. In the HTML I am able to get input from a user and then process a return email to them
The HTML looks like this:
<input type="text" class="input" value="e-mail" id="txtEmail" name="contactEmail" onclick="SelectAll('txtEmail');" >
and I'm using the following in the method
Dim sResponseToName As String = Request.Params("contactEmail").ToString
This part of my page works perfect as someone sends me a request I am about to direct an email to their "contactEmail"
However, in my aspx page it looks like this:
<asp:TextBox ID="contact_Email" CssClass="inputtext1" runat="server">
and the method used is:
Dim sResponseToName As String = Request.Params("contact_Email").ToString()
but no email is sent to the input email address.... If I hard code a random email instead of Request.Params("contact_Email").ToString() it works fine. But for some reason I can not get to the inputted user address.
kinda stumped, I've tried a few things but no luck. How do I get the Request.Params to work in an aspx, and do I need to add something in <asp:TextBox....> to reference it.

I want to notice that these events fire in the sequence they are shown. Now when there's an error, the db operations are rolled back, but the mail is sent anyway. I'm using Windows XP SP3, IIS 5.1, .Net 3.5, Visual Studio 2008. If I'm correct, TransactionScope uses MSDTC, right? I couldn't find anything about MSDTC working with smtp. Should it even work?

iam using asp.net 2.0 with c#.net.
in my application when client completes its shopping email will goes to user this works fine when there is internet connection is working fine, if there is some problem in internet connection if one mail stops then all the mails will be stopped even now internet works fine,
how to resend the emails using smtp server, is there any option to resend the emails automatically when internet works fine.

They work fine for the one app, but the other app gives me a relay error. Could this be because I'm using it on a separate domain? The one that works is "visitmychurch.tv" the other is "insidehcc.com".
I use a Smtp Client to email submitted information from an asp.net form. 3 users sent in their information and the user on the other end did not recieve either one of the emails. On the 2nd time around, she did recieve the emails. What could it be?

When sending email using MailClient, is it possible to have the .From property be for an email of a different domain than the credentials passed to the SMTP server? E.g., my credentials passed in are @mydomain.com, but the .From email is @anotherdomain.com. Or, must they be the same?
