Okay guys, here is my latest problem. I operate a single server here running SBS2003 and Exchange 2003. Using Exchange 2003, we send out an E-Newsletter once per week directly from the Exchange server to an entire distribution list. These are subscribers to the E-Newsletter. Here is my problem: I now have so many recipients on a particular domain (yahoo.com) that yahoo is rejecting my messages and responded with the error of "Too Many Recipients". I do not have time to place the Yahoo recipients in a different distribution list and send out to them seperately, as this would take a massive amount of time that just is not available. I need the newletter to be mailed out once and yet still get through to everyone on the list. We do not use a smart host, rather, we send directly from the Exchange Server. Is there a way to prevent this "Multiple Recipient Block" from happening so that all of my yahoo recipients get their newsletter from the Exchange Server? I know this is possible because I myself get spam every day at my personal yahoo email account, and I know that these spam emails are going to far more yahoo members than our legitimate e-newsletter is. Please help!!!
