IP Restrictions and You
Odds are the folks looking at this probably don’t do the bulk of the deployments for their companies. But in the odd chance that they are or have direct access to them, I’m going to touch on a very important aspect of ExchangeDefender deployment: IP restrictions. First we’ll start with a nice bright list of what the ranges are:
· 65.99.255.0/24
· 206.125.40.0/24
Now here’s why you need to first off add them for your client’s mail flow. Remember that in order for us to deliver mail on behalf of the original sender you have accept mail anonymously. This is very easy to do (it’s just the next tab on the receive connector GUI. The downside to allowing anonymous delivery WITHOUT the restrictions is that you’re one step away from being an “Open Relay”. If you’re an open relay, that will surely get your connection blacklisted on RBLs, it may get your access to our network revoked for a period of time based on the severity of the outbreak. So the cons of not setting these correctly are pretty huge:
· Interrupted/Inconsistent inbound mail flow
· Outbound mail flow restrictions

Support Refresher
Here we are again, another week and another quick reminder of how to test mail flow since it appears that ever week people forget the troubleshooting steps from last week.
Guys these steps are fool proof and give the answer every single time.

One of the tools recommended in the guide above is the Mail Log for Service Providers. Some of you are aware that we provide you with line by SMTP logs for every email. If your client is claiming their mail is not coming in this is the place to go. You log into https://admin.exchangedefender.com with your SP ID and its right there “Mail Log”. You put the to/from for the test message you sent them and voila. You have your answer, no opening a ticket, no calling anyone, no chatting with anyone. If the message isn’t listed there, check the MX record, if it’s not there then there are only two possibilities:
You typed the info in incorrectly.
We did not receive the message.
Please keep your eye on Social Media as we have a ton of new stuff coming down the pipe and that’s the best way to keep in touch.
