Hi,
I have a asp email script which uses cdosys to send emails with attahcments by iterating through a record set of 500 email addresses. However the script simply times out. I know you can increase the script timeout property in IIS but is there any other way of sending bulk emails with cdosys without it timing out?
Any help would be greatly appreciated.

you can response.flush
and you can do server.timeout = 5000000 (milliseconds)

Hi where do i include the response.flush line? is it after the send method?
Will this work for say 1000 email addresses and perhaps more?
The mail component built into ASP.Net can handle your bulk mailing, however it is more intended for single emails.
Generally any web scripting language (php, asp.net, etc.) are not that great of a match for a large, time consuming process - such as mailing a large list. This can cause threading issues, thread pools to get exhausted, etc.
What's a better method is to have a background script running that takes care of these, and the web page only triggers something so the other application knows it needs to go send the mails. This isn't always practical however.
The various bulk SMTP mailers, as you say, write the mail queue to the disk quickly so your asp.net page returns, then they send it in a background thread (almost like I am describing above, but not quite as good).
The built in component can do this, just don't specify a smtp server and it will spool the mail to the local SMTP server (note: SMTP service must be installed on server).

So how does one exactly run an ASP script that runs in a background thread? I've been searching on the net and cant for the life of me find any decent tutorials. Any sample code or example will be appreciated. Thanks
I know this response is a bit late, but I just found the site, and maybe someone in the future may find this info useful. There is an open source project called phplist (http://www.phplist.com/) that will help you with this task. It sounds like you have a windows server, so, if it's configured to support php, this solution may be perfect for you. You can configure the newsletter app to send out emails to X number of addresses, with 1 minute (or more) paused in between emails.
There are some ASP applications available for newsletters, however I'm not aware of one that offers pauses. At one point I was thinking about building an app that could do this, using AJAX and ASP, however, I don't know how great the need is. Let me know if there's interest in such an open source app.

Dear all,
I'm having major issues sending an email from my ASP.NET app.
I'm getting a "Could not create 'CDO.Message' object".
When I did a search for cdosys.dll in \win_location\system32, I could
not find it. So I copied it from another Windows 2003 server, where
it did exist. Another dependant file was missing too (inetcomm.dll).
