We have an Exchange 2003 server running on a SBS 2003 server. The server is accepting and sending mails.
Though when we test the mail server from mxtoolbox.com we get very slow responses. So I tried to do the same commands local on the server (telnet localhost 25). Even there i get very slow responses.
The initial connection is very fast, the answer to HELO is very fast.
The mail from:email@example.com is also fast. But when you do the rcpt to:firstname.lastname@example.org command it takes about 5 seconds before you get a response. Since I don't know which impact this has on our incomming mails I would like to resolve this as quick as possible.
Thanks in advance.
