How to prioritise emails sent to multiple addresses...?

[SUA_87]

I want to send an email in which I enter numerous addresses, but prioritise them so that there is only ever one recipient.

I.e if the 1st address is correct the message will go through to him/her and all subsequent recipients will be skipped.

If the 1st address is wrong however the email would go to the 2nd or if this is also incorrect to the 3rd etc etc until it finds an accurate recipient.

Hope thats clear!?

Also I would like the 1 successful address to show up in the 'to' field.

(I did consider BCCing but this would show nothing in the 'to' field and potentially send to multiple recipients).

Thanks!

You would have to write your own e-mail program to use SMTP directly.
