digitally signed messages
To defend from email abuse, more and more email servers
check the sender’s identity before delivering the message.
Sending emails without RealSender, your recipients can’t be sure
that the message received was generated by you.
Sending emails using RealSender, all the messages you send
are digitally signed, so that the recipients can trust them.
There are two standards to check the sender’s identity: SPF and DKIM.
RealSender offers both of them:
- SPF declares which are the authorized smtp servers for a certain domain
- DKIM digitally signs each message sent from a certain domain and its related smtp server
All the information used to check the DKIM signed messages
are saved and locked within the domain’s DNS settings
RealSender also provides:
smtp servers with dedicated ip
each customer receives a dedicated IP address the IP address is monitored daily over 60+ blacklists
secure smtp autentication
the server accepts only messages sent with SMTP authenticated over secure connection
using TLS or SSL (the communications are encrypted using a dedicated digital certificate)
sender’s address check

full email authentication
