Changes to IP and SPF records for ExchangeDefender
We’re growing, again, and that means more IP addresses and more networks. We expect a new growth bump to require additional hardware that will be added during Q1 and Q2 of this year so please keep an eye on this page.
Moving & Maintenance on mail1.ownwebnow.com
Our shared mail hosting infrastructure is moving. We’re going from 65.99.192.2 to 65.99.255.2. With the additional bandwidth and carriers, the network change will speed up the response time and transfer on larger attachments.
If you have your DNS record managed by us, there is nothing to worry about. We’ll take care of it.
If you have your DNS record managed externally, and have records that point to 65.99.192.2 manually – you will need to make changes. Since we don’t know where your record is or if you aren’t using us (you should be, that’s the assumed operational state) there is no way for us to notify you beyond this blog post so make sure that you make the change ASAP. The IP address at 65.99.192.2 will cease to operate Monday, January 25th, 2010.
We have a scheduled maintenance window at 10 PM EST on Thursday, January 21st, during which time there will only be intermittent access to our mail infrastructure.
ExchangeDefender SPF records
If you are using SPF records as a part of your domain name to limit joe-job’s and spoofing you’re probably aware of having to manually add IP addresses to it when a new ExchangeDefender outbound network is created. Good news – you don’t have to do it manually any more! Just add the following directive to your SPF record (in bold):
“v-spf1 include:exchangedefender.com –all”
Adding the include:exchangedefender.com to your SPF TXT field will include all of the defined outbound SMTP servers used by ExchangeDefender so you don’t have to manage them manually. Naturally, you should also list all of your other SMTP servers that relay mail for your domain. Note: ExchangeDefender does not offer technical support for SPF records as they are not a part of our service. However, if you wish to use them and know how to implement them, ExchangeDefender is making it easier to track our records.
