We have one SBS 2011 with exchange 2010 server and we are not receiving any email as of 24 hours ago. Our spamfilter can connect to the server, port 25 is open and everything looks perfect but email doesn't show up in the mailbox. OWA is working and phones are connected but no new email. we cannot receiving internally or externally--- When we try to send email using telnet we get an error that it is unable to relay. Any ideas. Can we delete the two connectors mail.domain.local & mail.domain.com and the recreate them?
