What are the IP addresses of Laposta's mail servers?

Your newsletter contains your sender address as the From address. This gives your subscribers the impression that the newsletter comes from you. In reality, your newsletters are sent through our system. 

We use servers at several locations to send newsletters. 

Some system administrators want to know which domain names and IP addresses we use. The IP ranges from which email can be sent are as follows:

All emails from Laposta have one of our domain names (for example mail.eprov.eu) as invisible sender (Return-Path). You can change this to your own domain under Settings → Authentication.
