Which IP-addresses do Laposta’s mail servers use?

Your newsletter displays your sender address as the From address. This makes it appear to your subscribers as if the newsletter was sent directly by you. In fact, your newsletters are sent via Laposta’s servers, which are situated in multiple locations.

System administrators often want to know which domain names and IP addresses Laposta uses for this. These are the IP ranges from which emails can be sent:

45.152.251.0/24
91.247.184.0/24
161.51.101.0/24
188.241.247.0/24
193.160.154.0/24

All emails from Laposta have a Laposta domain name as the invisible sender (Return-Path), for example mail.eprov.eu. If you want to use your own domain name there, you can change this under Settings → Authentication by authenticating your domain.
