Spam and Rules at Computer Solutions

CS // 24 Apr 2013 // Comments Off on Spam and Rules at Computer Solutions

As one of the main contention points people have with mail service is either the amount of spam they receive, or the amount of legitimate email we block, we’ve decided to put the solution in your hands.

We’ve added user access to the blocking implementation we use at Computer Solutions.

For a quite rerun on this our incoming mail rules are as follows:

• Sending Server has a valid Reverse DNS Entry
• Sending Server conforms to mail RFC’s
• Sending Server is not listed in any of the following Antispam Service Lists zen.spamhaus.org cblplus.anti-spam.org.cn cdl.anti-spam.org.cn bl.spamcop.net dnsbl.njabl.org
• Mail does not contain a virus, malware or similar content.
• Mail is addressed to a valid sender.
• Recipients mailbox is not full.

We’re giving you access to do what you want with regards to incoming spam blocks.
If you decide that our heinous blocking of senders who’s servers are _definitely_ listed in spam listings is not to your taste, then you can change that.

If you want to whitelist any incoming mail you can do the following:

1) Login as the postmaster account for your domain at http://rules.computersolutions.cn (in the example below, I’m editing my own account, you’ll need to use YOUR postmaster@yourdomain.com / password!)

2) Select Domain Wide Focus

3) Click Add a domain specific rule (this will apply to all messages received for your domain – i.e. anything @yourdomainname.com)

4) Setup appropriate rules (there are a number of options – in the example below I’m whitelisting all incoming mail).

5) Note that the System rules below are now greyed out (assuming you whitelisted as per example above).
Thats because they no longer apply!

In future we will be pushing clients to use this interface for their unblocking / blocking requirements, so that the needs of the few outvote the needs of the many, and your incoming email can go where no wo/man has gone before.
