Whats a groupsbox?
It is a specialized mailbox to receive e-mail that typically has large attachments. It limits the possible senders (for now, only Yahoo Groups) so that you get no spam. Our groupsboxes post-process your e-mails to decode the attachments to binary files and classify them by group. Because groupsboxes need to be very large (from 1 GB to 20 GB), the incoming and outgoing bandwidth (data transfer) becomes the crucial factor in estimating usage, not storage space as with smaller boxes (1 GB or less). For example, if you have a 2.5 GB generic mailbox and fill it up and empty it once a day, by the end of the month you will have consumed 150 GB of bandwidth (75 GB in and 75 GB out)! That costs way lot more than 2.5 GB of storage (more than $1500/month as opposed to about $125/month). Our groupsboxes also automatically adjusts the volume of e-mail you receive based on groups priorities you set. With a generic mailbox, if you receive too much mail, it will bounce back to Yahoo, and set a bounce
