Please help. We have an SBS server 2003 std edition.
My quesry is in regards to exchange. Up until yesterday i am unable to send e-mail. I can see in system manager that the queue shows aprox 200 e-mails. The additional info is "The remote server did not respond to a connection attempt"
I had looked over my settings for over an hour and everything looks fine and unchanged. The only thing that happened was when i thought i had exhausted all possibilities i checked if the server was black listed and i found it was blacklisted by baracuda spam on the net. I e-mailed and had this lifted and they confirmed by e-mail that we have been removed.
I can confirm that no other servers have stopped us. My mail still wont go. I have restarted the exchange server services, the entire server and no luck.
I recreated y default SMTP virtual server and still no luck. I do use DYNDNS's outbound mail hop service to send mail via a setting for smart host. I tried the alternative TCP ports and no luck.
I have e-mailed them to see if they have restricted me but no answer yet. I did log into my account and could see nothing informing me i have been blocked.
What should i try next. The only thing i have not tried and has always been a grey area for me is telnet to see if the ports are open. Will this help?
