I know how to send emails, but is it possible to send out text messages?
View 8 RepliesI'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 RepliesIf 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.

i m sending mail by this method but it generate exception"SMTP EXCEPTION NOT HANDELED BY USER"
and in details it shows as:"base {System.Exception} = {"Failure sending mail."}
[System.Net.Mail.SmtpException] = {"Failure sending mail."}
StackTrace = " at System.Net.Mail.SmtpClient.Send(MailMessage message)
at ExptMail.Button1_Click(Object sender, EventArgs e) in f:\dh\websites\ExptMail.aspx.cs:line 32""
The objective is to send automated emails to which of whom come from the results of my LINQ to SQL script. As I am not sure on 'automated' stuff I was going to approach this in the aspect of having a field in the table that the results are taken from change after the emails have been sent i.e. obj.EmailSent = true; - So that everytime the admin homepage is loaded it isnt sending it out again (eliminating duplication).
From that I would have to create a method to detect a new year and upon that reset all entries of the EmailSent field in the DB table to 'false', but for now its just the initial problem thats causing confusion.
I was going to opt for a 'foreach' solution so that all the recipients, individually, get their emails and not all together. Its the 'foreach' I'm not sure on as well as setting all the results collected to the new value of 'EmailSent' to 'true'.
Here is my attempt:

how i can send emails with a return path in ASP.net 3.5 / C# 3.5. I know this was possible few years back but now due to spoofing issues this is not possible. I have been looking on internet but no use. I want the emails if bounced, should reach my bounce mail box, which could be like Bounce@mydomain.com.
View 1 RepliesI have a web application that allows a user to "join" our site. When the CreateUserWizard completes, I just have the code below in the bottom of my wizard tags; and this works!

I need to now add a second email that'll tell site admins that this particular user has requested access. So the user gets an email saying for registering... account is pending authorization"! At the same time I need a second email to be sent to the site admins (just one email address) stating something like "A new user <%username%> has requested to join your site". This is what I tried, but doesn't work:
[Code]....
Of course this isn't working because the CreateUserWizard automatically sends it to the CreateUserWizard.Email. I need to hardcode in the address I want the second email. So, I've tried this in my Register.aspx.vb file (I call this function from my Register.aspx file using "OnCreatedUser"):

View 2 RepliesI try to send emails through ASP.NET interface and can't get it to work. Emails are sent, but only if the receiver of the email has the same domain name as my server (receiver@mydomain.com). The weird thing is, I actually CAN send such emails from any email program. So it seems that my Web.config file is missing something (?), although it looks ok (for me):

I've gone through this link. (http://connect.microsoft.com/VisualStudio/feedback/details/544562/cannot-send-e-mails-with-large-attachments-system-net-mail-smtpclient-system-net-mail-mailmessage)
It is not possible to send an e-mail with an attachment larger than 4 MB in .NET Framework 4.0. The same code works for small and large files if you set the target platform from .NET Framework 4.0 to .NET Framework 3.5. So this cannot be a problem with our mail-configuration! I get no error if I attach e.g. 10 files of 2 MB! I searched through Google but I didn't get it.
Workaround solution is not working fine as expected. After using this workaround for a while, I found that some files are corrupted. So this is not a solution for this bug.
We've applied that Microsoft patch and we're still seeing the issue?
