TYPO3 Core

I'm speaking of the standard TYPO3 mail form.

This is indeed a bug. In t3lib_formmail, the ReturnPath is using the $TYPO3_CONF_VARS['SYS']['forceReturnPath'] variable as the address, while it is only a boolean (0 / 1):

if ($GLOBALS['TYPO3_CONF_VARS']['SYS']['forceReturnPath']) {
                        $this->returnPath = $GLOBALS['TYPO3_CONF_VARS']['SYS']['forceReturnPath'];
                        $this->mailMessage->setReturnPath($this->returnPath);
                }

This is what throws this exception. Since forceReturnPath setting is marked as "deprecated" in 4.5, we should drop the above mentioned check (SwiftMail will add a good Return-Path anyway)

=> pending in core, thanks for reporting!

Steffen, as I just upgraded a site to 4.5.0 I started getting this same error because my recipient email address was a comma separated list of two addresses.

I can make a new email alias to handle my problem, but it sounds like lost functionality.

(I believe the formhandler extension happily accommodates a list of addresses. But I would rather not implement that when a simple stock form would suffice.)

Does this need to be a new issue or can it get bundled in here?

Curt: if your trouble doesn't come from a set "forceReturnPath=1" in your localconf.php, then this is something else. In this case, please file that as a new issue in our tracker, send a reminder to myself (Ernesto Baschny) and I can take a look. Thanks!
