Enhanced SMTP Security requirements now in effect
As noted previously (and discussed in our portal, conference call and newsletters) the enhanced SMTP security policies are now in place. Going forward, all SMTP traffic on our networks (inbound and outbound) will have to pass through ExchangeDefender in order to reach it’s target server. This network change affects all servers and all networks controlled by Own Web Now Corp.
If you have a requirement for plain SMTP connectivity for mail relay please either consider establishing a VPN directly to your server (if you are a dedicated/virtual customer) or upgrade to Microsoft Outlook and use RPC-over-HTTPS proxy available for our hosting customers. If you require SMTP for your client needs (Thunderbird, Outlook Express) please use SMTP-over-SSL (TLS) in your setup.
Despite enhancements in the security products and reduced cost of antivirus products, SMTP based attacks have continued to rise through 2009. We are committed to protecting our customers and limiting exposure that comes with an open SMTP port.
