Incoming Email being blocked

Our servers preform server-side spam filtering automatically.  Sometimes it is possible that a sender who had sent email to you in the past is suddenly being blocked or listed as [BULK] or [SPAM].  This likely has to do with the ever changing environment with email servers and the traits that real spammers use.
The recommended way to prevent legitimate messages from being blocked or classified as spam is to add them to your Whitelist.  It is an easy process and will ensure that their messages always make it through to you.
