One IMAP Account on 4 computers

Hi, I check my email from 4 different computers and run it as an IMAP type account. The instructions tell me to put the Spam folder on my mac which downloads the mail to my hard drive. My question is, would it be better to keep it off the hard drive so it syncs with all the computers or do I need to train each computer to filter the spam. Thanks, Nancy

Although other configurations are possible, I recommend the one in the instructions. This way you won’t fill up your server with spam, and if a spam message isn’t caught it makes it easier to know which copy of SpamSieve missed it, and to train that SpamSieve that it’s spam.
