[TYPO3] standard mailform additional header Reply-To ??

[dieter orens]

When using the typo3 mailform, I want to know how to make it use the 
additional headers 'reply to' of the php mail function. I want that the 
email address automatically is in the sender-part, so I can reply to it.
I can do it with plain php, but I figured that this should be possible 
with the mailform or not?

thanx.
