Smtp :: Sending Back To Back Emails?
Jun 17, 2011
We are having problems with sending back to back emails on one of our web sites. The site is built with .net framework 2.0.We can send the first email without any problems on every try. But to send a second email you need to wait about 20-30 minutes.the problem.One thing we tried was changing the smtp email server. We tried a third party smtp server but the same problem persisted. So I think the problem is not with the smtp server but with our .net code.

I've built a newsletter system which tracks:
Openings
Link clicks
Unsubscriptions
However, I need to find a way of tracking which newsletter emails 'bounced back'.
Has anyone done this before and whats the best way of doing it?

I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

Is there anyway you can send information back to the original creator of the program? Here is a quick example- I made a little program that gives you general information about your computer, when you click a button it sets the text box to specific information. One of the text boxes gives you the Version of your OS. I would like to know if there is a way to send the information in that text box back to me when someone clicks it and they are connected to the internet. FYI I would tell the person who clicks it before so that I am not stealing information, plus what is there to steal from a simple program I made.

I've created a simple licensing system for a friend who has created visual basic programs which he sells at a few dollars each (they're speciality programs).The licensing system is coded in PHP (I'm a PHP coder), and the system requires the user to input their license key upon start up, if there is not already an activated key (which is created in a .txt doc)

We have a server application and a client application that communicates with each other using socket.
When the server application sends 2 messages about 16-31 ms apart, the 1st message is received by the client application with little delay (like 16-32 ms after it was sent). But the 2nd message is received by the client application a lot later (like 200 ms later) than when it was sent.
We already disabled Nagle algorithm (set NoDelay = True) in the socket in both the server and client application.

I am creating an application that will be faced with multiple decisions to make and I want to know if it is possible to create around 20 if statements to excute or decide between before excuting?
The application will encounter multiple websites but each website will have the same elements but not neccessary in the same order so I was going to tell the app to loop through the IF statement and if the condition is met to run that sub routine where it starts over and loops through the IF statements until next condition is met.
Is this possible in VB.NET or is 20 or so IF statements to many to use at once?[code]...

I want to send an email that contains an attachment via vb.net and smtp. I used gmail as smtp server. This project works correctly when the size of attachment size is lower than 1Mb. When the size of the file is bigger than this size it makes an error. The message is this: "ContextSwitchDeadlock was detectedMessage: The CLR has been unable to transition from COM context 0x652fd8 to COM context 0x653148 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations."I extended the timeout period but this message is shown.

I have been searching for the answer to this for quite a while but none answer me exactly. Here is my problem, I want my user to be able to send an e-mail by clicking on a button "Send" and for this e-mailk to take the e-mail address from a text box and the message from a text box (Subject can be hard coded as it will always be the same) but I need to do it without using SMPT protocols as I don't want the user to have to input lots of information regarding their e-mail etc. Is there any way to do this.

Now there's a user "A" who has 100 followers...now what i want to do is whenever user "A" submits an article in the website all his followers should get an email with the article link...that is okay i can do it.
Problem: Now, there's a submit button on the page which stores the article in the DB and sends email to the followers...as there are many followers it takes a lot of time sending the emails...so the page keeps showing loading msg till all the emails are sent..how can i send all the emails asynchronously ??
i mean after the article has been submitted ...the emails should go automatically to the followers without putting the email sending function in the click event of the button....hope am not confusing you folks.
can i do something like store the article in the DB , redirect to the article page , start sending emails in a batch of 10 per 10 mins automatically...this process should start as soon as an article has been submitted by an user.

I have been trying to make my own app for sending emails. But I have been trying to make it where I don't have to sign into my hotmail account, it just does it automatically. Then all I need to do is fill out the recipients, subject, and body for the message and hit send but I am having issues. I can't for the life of me get it to work. After a week of messing around with it and scouring the internet for help, I have gotten to where the only error I get is, failure to send message.
Imports System.Net.Mail
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[code]....
I have been working on this because I can't use Outlook with hotmail and I figured it would be interesting to try, but it turns out to be a lot harder than I expected.

I'm currently using SmtpClient to send emails to users that register or sign up for an event.When they click register it saves the info and calls the send email function, but it takes slightly less than a second to send an email which is too long.Is there a way to save the users info and after the page is loaded it calls the send email function from vb in the background.
