There is an opportunity to set a condition of check of messages (the address of the sender, a theme of the message, contains attachements whether or not). If they are given, the program informs you only on reception of the letters satisfying these conditions.
Also it is possible to conduct the list of undesirable addresses ("antispam") which automatically leave directly from a server. The address can be specified obviously or can be specified its part only (for example @mail.com - in this case all letters witch address containing "mail.com" will be deleted from mail-server). It is possible to set any quantity of mail servers.
