It means that if anyone wants an email box ending by @vtes.be , it is now possible.
If you are interested, just contact me in private with the username you would like (eg nickname or anything you want). I'll create your email box and give you a password (that can be changed later).
To read your emails, you will be able to use this link : www.vtes.be/webmail
Or, you can add an email account on your device (iPhone, Android, Outlook, etc.) with these settings :
protocol : IMAP
server : mail.vtes.be (for both receiving and sending)
receiving port : 993
sending port : 587
use SSL : yes
use authentication : yes
I'm not sure this feature is very useful to the community, but it's an "option" .... so why not
