need an alternative to mailto to open new mail message

Question

Hi We are developing a portal. There is a requirement to open new mail message in the outlook of user machine with the TO CC BCC populated programmatically. To achieve this we used the following syntax  mailto:mail1@domain.com?cc=mail2@domain.com&bcc=mail3@domain.com  This works fine when the number of recipients is less. However we need to populate the To CC BCC list from the result set of a query which may be even more than 1000 mail ids. In such scenarios the above method fails. I came to know that the maximum limit of characters allowed is 456 when browsing through the following link http://lists.evolt.org/archive/Week-of-Mon-20010813/055130.html If any of you know how to overcome this limitation of mailto or an alternative to mailto kindly let me know. Thanks in advance!

Yes the mailto protocol is explicitly designed to be used to create simple messages. It is explicitly designed to not be used in the manner you need. Are you using .Net? If so then look at the System.Net.Mail Namespace as in: http://msdn.microsoft.com/en-us/library/system.net.mail.aspx If not .Net then if it is Windows use CDO for Windows 2000 as in: http://msdn.microsoft.com/en-us/library/ms527525(EXCHG.10).aspx http://msdn.microsoft.com/en-us/library/ms978698.aspx Note that there are more than one version of software called CDO and some of them do things that another CDO does not.
