Hi Yves

After the installation of Matukio 6.0.7, the Joomla bug causing the invoice not being send is solved. However, the Reply-To header is no longer correct. The general email address is used, instead of the email address of the organiser. Do you think that's something that can be fixed by your workaround too?

ps: We're using a SendGrid account as our external SMTP server. So in case the "Reply-to" header is not explicitly added to the header, the general email address will be used instead.
