This category is for anti-spam programs that operate on mail servers. The difference between an anti-spam program running on a mail server and an anti-spam program operating on a mail client is that the filter running on the server can remove spam from everyone's mailbox at the same time, instead of from just one user's mailbox. Server-level programs are installed by a systems administrator, and individual users do not need to maintain them.
Spam filters for a specific mail server (for example, writing filters for sendmail) are listed in the category devoted to that mail server. This category contains standalone software (and hardware) designed for spam filtering.
