What can I check for if I'm not receiving e-mails? I'm running Exchange 2000 with Outlook XP and as of yesterday I have not been able to receive e-mails from the outside. We received an e-mail when attempting to send an e-mail to our Mexico location stating that we were not allowed because we were part of blacklist. I sent a IP removal but I'm still not able to send to outside of my domain. I looked and made sure we were not relaying. Any hints???
