[HELP] asp.net bulk emailer


Question

I'm running into a problem with a bulk emailing asp.net application that I?ve been trying to fix for two weeks. Here is a brief description of the problem.

All of a sudden (aka for a reason that isn't immediately obvious) a bulk emailing application built in asp.net vb 1.1 has started sending doubles of every email I tried to send. This application pulls email addresses from our employee database and sends one message to each user. The system is even confirming that the right number of messages was send, but exactly double that is actually received, two by each user. The problem seems to correct it's self when the system is restarted and will work fine for a period of time. We are using Mail Enable. It's a free solution but for our purposes it works since we are only using the system to send out email, not receive. I'm thinking it's something in the mail enable's SMTP, maybe overflow/memory related since the problem is solved on restart.

I'm trying to find someone that wouldn't mind taking a few min to jump into this problem and see if they could help me out. I'm trying to avoid 5000 users posting their opinions on here. I have tried everything under the sun that I can think of to solve this and nothing has worked. If you think you are up to the task and wouldn?t mind donating a little friendly advice in a constructive manor please email or pm me. I'll go into more detail with you at that point as to what trouble shooting methods I have already tried. Appreciate the help!

I have no experience with Mail Enable, but does it have any features you will use that isn't already available in the System.Mail namespace.

I'm guessing the problem lies in one of these two systems:

1) Mail Enable (check their forums)

2) Your SMTP Server

I'm leaning towards something with mail enable for a few reasons.

Keep in mind that this was working for over a year without any problems.

I've changed the time between the sends and lowered the number sent in each run.

it's only sending about 600 and thats over 10 minutes.

It usually works fine for a few days, I use it a few times a day and then all of a sudden it'll start duplicating the emails. I restart the server and it works fine for a few days.

Thanks for the help!
