Spam Lists

Spam - the use of electronic mail systems to send unsolicited messages, usually of an advertising nature.
A spam sheet is a database that determines whether a mail server with a specified IP address sends messages that can be considered spam. There are many spam sheets with a common goal - to keep user mailboxes from spam messages. Understanding how spam works works can help improve the efficiency of email delivery, as well as the reputation of your emails.

The Spam Lists tool checks if your mail server is listed as a spam list - a list of servers that send spam messages and receive messages from which it will be blocked.

Mail Relay

Simple mail transfer protocol relay (SMTP relay) is a service that is used as a means of transporting e-mail messages between various e-mail hosting services, servers or domains.
Open mail relay is an SMTP server configured in such a way that it allows anyone on the Internet to send e-mail through it, and not just mail intended for known users or sent from well-known users.

The Mail Relay tool checks whether the mail server can be used as an open mail relay.

SPF Generator


SPF (Sender Policy Framework) is a TXT record in DNS that is used to prevent unauthorized e-mail messages.
With a single TXT record, you can specify all the IP addresses used to send mail and tell the receiving server that only outgoing servers listed in the list are allowed.

The tool uses a convenient interface and simplifies the creation of SPF records.

Mail Trace

Using the technical information of the message headers, the tool analyzes the route of the accesses.

The parameter is the technical title of the letter.
