Emailing with variable from address

Hi

I have a system where the 'from' address is entered by the user(s) so that it shows to the recipient as 'from' (this is important, as the recipient catalogues incoming emails by this address).

However on numerous occasions the user(s) inputs an incorrect email address in the form and using 'mail' via our organisations smtp servers this then appears as incorrect and non valid email address and bounces it and in turn the postmaster complains to me.

Q. Is there a way using UM to have a fixed "from" e.g. <me@example.com> so that the smtp server sees this and sends the email but the recipient sees <thesender@example.com> as both the 'sender' and 'reply to' address.

I have scanned php mail and think I might be able to use the -f parameter (I think, my php is not up to that level) it seems somehow modifying the envelope may have an way of doing this but it's beyond me. I appreciate this is probably a non starter but any advice or ideas would be well received.

No, you wont be able to show the replay to address as the from address to the recipient.

I think the best way around this would be to have a First name and last name form element, and use those as the From display name:

<?php echo((isset($_POST["UserFirstName"]))?$_POST["UserFirstName"]:"") ?> <?php echo((isset($_POST["UserLastName"]))?$_POST["UserLastName"]:"") ?>

this way the From display name instead of the address will be shown to the recipient

Yes that seems very logical - I'll do that many thanks for the input Jason
