As part of our ongoing fight against spam, Runbox has recently deployed a new cluster of spam filter servers and made a few changes to how we deal with spam.
We now block a lot more spam by rejecting connections from servers that are known to send spam. Most of these connections are from virus infected computers, and it is relatively easy to identify these machines via their IP addresses.
Another change we’ve made is to upgrade SpamAssassin so that it performs more extensive checks of incoming mail.
This is the first among several steps we are taking to clear your Inbox of spam, and we will post more news about this in the near future.
We’ve also decided to tighten our policies on bulk mailing using Runbox’ outgoing email servers to prevent Runbox from ending up on blacklists used by other email services.
As email use continues to grow and more people around the world are online, so does the amount of email sent for marketing and promotional reasons. Often mailing lists are badly managed and people receive email they no longer want, so they mark them as spam instead of unsubscribing from them.
Meanwhile spam systems are getting smarter, and email providers create statistics from the actions of their customers. If a customer marks a message as spam (whether it is spam or not), this is recorded in a database, and it can result in those domains and server IP addresses being blocked.
Only a very small number of Runbox customers use our services for marketing and promotional messages, but this can still have an adverse affect on all Runbox customers. Therefore we have decided that Runbox can no longer be used for bulk mailing, and we are now changing our Terms of Service to reflect this.
