Hi, I need to get unread emails from my inbox - to handle bounce-backs messages.
I don't need to get entire message. What I need is only: Subject and body only from unread e-mails.
 
I probably have to use IMAP, so could recommend me an "open-source" and good solution? so I can sell this software without any problems?
 
But, when smtp server don't support IMAP, I have to use POP3? That project will be good for that? Or maybe there is some other, better way ?
 
Thanks for help,
 
-----------------------------------------------------------------------------------------------
 
UPDATE:
I've got an idea.
I can read how many messages are in inbox. So, I also can get the last one.
I can check if there is a bounce-back message in timer (every 5 minutes for example). I could get messages one by one, and check the date. If the message was sent before 5 min ago, i would break.
In that solution, I will not get all messages from an inbox every time. Is that good solution ?
 
The pseudo-code of my idea:
TIMER( Tick every 5minutes )
{
    (LOCK)
    loop(on inbox from end to begin)
    {
        // If the message date is older then "5 minutes ago" break
        if (message date < DateTime.Now.AddMinutes(-5);)
        {
            if (the subject is "Undelivered Mail Returned to Sender")
            {
                // Here I will parse message so that I will know the addresse
                // And removie that addresse from my list.
            }
        }
        else
            break;
    }
    (UNLOCK)
}

POP3 does not have the capability to track unread emails. If your server does not support IMAP you try to use outlook automation.

Thank you, but I found <a href="http://www.afterlogic.com/mailbee-net/pop3-component">here</a> sth like that:
POP3 Object:
- Download entire messages
- Download headers only
- UNIQUE Download messages/headers in PIPELINING mode - can boost performance up to 1000%
- UNIQUE Download messages with a single line of code (QuickDownloadMessage)
 
How do you explain that?

Yeah sure, there ar some components that can do that easier for you. I gave you free way to do it.

I've updated question a little bit, could you tell mi if this is good idea?
luisnike19 at 14-Jul-11 17:53pm
   
That could work but I don't like that idea. That could cause a lot of time, let's think in a case when you always receive many e-mails by hour. You'll need to iterate each e-mail one by one and that will consume a lot of time and the process can be very slow. And then if a case you inbox has 100000 that will cause a lot of time to process just the last 5 min or something

But, I'm not sure you understand me. The largest amount of emails, which I will have to read is as many as has been delivered in 5 last minutes. In my question I add a pseudo-code of the algorithm.

Imagine another situation - you have lost connection for 1 hour, and something important arrived during this period?
So probably you should at least have not 5 minutes, but since the last time you successfully connected, or something like this

Yes, good point. So, I think that will be good solution, to solve handling bounce-backs over pop3 without outlook. Thank you.

Your idea is not good. But anyway is your code. I hope it works for you.
mnd017 at 15-Jul-11 11:51am
   
I know it will works. But I would like to use possibly the best solution for dealing with bounce-backs emails with server without IMAP,only with POP3 and without outlook. Could you recommend me sth better? Would be great

Review this link, I hope it helps. It uses an exchange server.
