Our company relocated to a new location, and we just installed the new T-1 yesterday. Everything looks good, except that i cannot SEND OUT emails externally. All outbound emails are just sitting in the queue. Receiving is no problem.
Upon checking the queue, the message at the bottom just says "the remote server did not respond to a connection attempt."
Telnet to external servers are good, and i was able to send email to an external server using the telnet.
I'm not using the SMTP connector, it's just straight virtual SMTP server. I'm running a DNS server on the same machine, and the SMTP is also configured to use external DNS server in the advanced delivery configuration.
mx record and the a record was updated yesterday and it looks good because i have no trouble receving email from anyone.
please help. thank you.
