SpamAssassin and the spam-filtering community often refer to non-spam messages as ham. This feature requires SpamAssassin 3. Spammers cannot do these computations and still send out huge amounts of mail rapidly.

SpamAssassin combines message format validation, content-filtering, and the ability to consult network-based blacklists.

The senders must reply to the challenge in some fashion that verifies their email addresses and generally speaking proves that they are human beings, rather than an automated bulk mail program the response.

After a successful response, the system allows messages from the sender to be accepted, rather than holding them. In greylisting systems, the mail server initially returns a temporary SMTP Simple Mail Transfer Protocol failure code to messages from new senders or sending systems. If the sending system attempts to resend the message after a reasonable time period, the mail server accepts the message and subsequent messages from the sending host.

Because spammers are likely either to treat the temporary failure as a permanent failure, or to attempt to deliver messages continually during the greylisting time period, their messages are not received. In time-limited address systems, users generate unique variations of their email address to include in different web forms, email messages, newsgroup postings, etc.

Addresses may be valid only for a limited time or may be valid until revoked by the user.

In micropayment systems, senders must pay a small fee for each message they send, making large-scale spam runs costly. In some of these systems, the micropayment is refunded when the recipient determines that the message is in fact non-spam. SpamAssassin 3. At heart, SpamAssassin is a set of modules written in the Perl programming language, along with a Perl script that accepts a message on standard input and checks it using the modules.

For higher-performance applications, SpamAssassin also includes a daemonized version of the spam-checker and a client program in C that can accept a message on standard input and check it with the daemon. The per-user configuration can also be stored in an SQL database. There are several ways that this can be done.

Figure shows a typical mail transmission.

Each has advantages and disadvantages. Spam-checking is one kind of filtering that can be usefully performed at the MTA; virus-checking is another.

In many cases, sophisticated filtering daemons have been developed for specific MTAs, and these daemons are capable of calling SpamAssassin to perform spam checks.
