Yesterday we stopped receiving e-mail altogether. After a little investigation I found out that our domain had expired at Network Solutions. I renewed the domain and started receiving e-mail within 15 minutes. I thought at this time that the problem was solved but later in the afternoon a number of people started coming to me telling me that they were expection e-mails from people and were not receiving them. I ran a test sending from my own personal e-mail and also never received it. I spoke to Network Solutions this morning and they suggested I call my ISP. I spoke to my ISP (Telcove) and they told me that the MX records have not been updated in 3 years and that if I was receiving any mail at all that they were fine. I am running Windows 2003 SBS with Exchange 2003. I also notice that I am not receiving anything from out e-commerce website (orders or product questions). Can anyone point me in the right direction about this problem ???
