Is it possible to use my own mailserver (use a non-WEM email address as sender)?

Yes, it is possible to use your own mailserver in WEM projects if you want to use a non-WEM email address as sender. There are 2 ways to implement this:

1. Using our default mail server. Note that our server must be authorized via an SPF record in DNS from your domain.
2. Another option is to directly use your own mail server. In WEM you can implement / manage the smtp settings on the workspace level. Note that you have to put our outbound IP address into the IP whitelist on your (customer) firewall.
