5. From SPAMfighter SMTP Anti Spam Server to SPAMfighter Mail Gateway This guide will assist you in going from the SPAMfighter SMTP Anti Spam Server to the SPAMfighter Mail Gateway It is strongly advised that you read the SPAMfighter Mail Gateway User Manual before reading this guide do not worry as most of it is pictures and can be skimmed through quickly In this guide the SPAMfighter SMTP Anti Spam Server will be referred to as SMTP filter and the SPAMfighter Mail Gateway will be referred to as SMG Main differences between the SMTP filter and the SMG The SMTP filter scan the emails as they pass through the filter to the mail server behind whereas the SMG receives the mails filters them and only if they pass the tests set up will they be forwarded to the mail server behind This means that the mail server will have much less activity with the SMG then with the SMTP filter With the SMG you need only one IP address for incoming mail traffic no matter how many mail servers it filters for whereas with the SMTP filter you would need one for each mail server with its own IP behind the SMTP filter The SMG have quarantine functionality This meant that incoming emails which are filtered as spam can be saved for a time period so the users can see and unblock the mail themselves if it has been erroneously blocked as spam You now set up the mailboxes you want filtering for This guarantees that you only receive mail for mailbo
