Each hosting account package includes spam & virus filtering.
Basic spam & virus filtering is provided using SpamAssassin.
Messages perceived to be spam will be tagged in the subject line with * * SPAM ** or a similar heading. That way, you can use your computer's mail program to sort those messages into a spam folder. Viruses are deleted when they are detected.
If you would like to have a daily quarantine report generated, you will want to sign up for one of the hosting products under which premium spam & virus filtering is offered. With premium filtering, you have a wide array of options, including creating of white and black lists, log searching, and the creation of custom filters.
