Customize UddeIM Premium

Hi guys,

I would like to purchase UddeIM with its premium file attachment plugin.
Will the attached file also be attached to the notification email?

I need to customize the following functions in the UddeIM component:

.) Add subject field + will also be the subject of the notification mail.
.) Attached file to the notification mail. (if not done auto by UddeIM)
.) Rewrite the "from" + "reply-to" fields of the notification mail to the composers email address.

The Goal is to let the communication happen outside of the website in everybodys email client. So users only need to login if they want to write a new message.

Could this support forum guide me? Not doing the work for me, just telling me where to generally look for the right functions?

Thanks for help and sorry for my bad english.

The attachment will not be added to the notification email and also the origin's email address will not be used as sender address in order to keep the sender's privacy. The idea behind a PMS is to offer a closed communication that keeps your privacy.
