We offer our mdex customers a mail relay that allows you to send e-mails with a maximum size of 100 MB to the desired recipient. Please use the following SMTP settings in your e-mail client:

SMTP Server:	mailrelay.mdex.de
SMTP Port:	25
Authentication:	Off 1

¹ If the e-mail client requires a Username and Password, use e.g. Username: mdex | Password: mdex.

Important notes:

• The mdex mailrelay is only available when the device is connected to mdex.
  To do this, you must use an IP service mdex fixed.IP+, mdex public.IP, mdex mobile.LAN Paket or an mdexSIM.
  (The mdex access only requires the Attributes "Master" or "Slave" property. The additional option "Internet" is not required to use the mailrelay).

• The mdex Mailrelay can only send e-mails.
  If you have not set a valid sender in your e-mail settings, it can not be answered by the recipient.
