Timeout error when sending large email

Hi:

I have a problem when sending large email(more than 20Mb) from a web page. I got timeout error. How to overcome this problem? I am thinking to have a thread to send email. Once the thread starts, return response to client immediately. The client should be able to kee checking if the thread is finished. If it's finished, return back a value. I don't know whether it works or not. Any idea, please.

Thanks,

Dennis

You need to use the async calls and feed back a little bit of data at a time
to keep the browser happy.

Actually, if you're sending via a local SMTP service I have found that constructing a .msg formatted email and dumping it to the inetpub\mailroot\pickup folder is by far the best way. By doing this, it writes out the whole message and the pickup folder is essentially putting it in queue and allows the page to continue loading. You'll need to read up a bit more about it and MIME encoding, but it's my favorite way.

If you're using a remote SMTP service you've got no choice but to do as the other post instructed with async or feeding data to browser at intervals to it from timing out. (You can do Response.Write("<I></I>"); as long as you want. Note that this is generally a bad practice though)
