Dear,

I have configure a postfix mail server. Here I have problem of sending mail. After sending mail when i see maillog file if relay=none then mail get deferred and user not getting mail. But when relay= any ip or address then user getting mail. So what is the problem of relay=none. Could anybody help me about that. here i have add some maillog information.

to=<cn@hotmail.com>, relay=none, delay=69, delays=48/0.02/21/0, dsn=4.4.1, status=deferred (connect to mx.fakemx.net[46.4.35.23]:25: Connection timed out)

Off hand, it sounds like port 25 may be blocked to all but your ISP's dedicated email server. You might want to check into this by seeing if you can telnet in and our on port 25.

Mr. Noway2
Yes I can telnet port 25 on this server. And port 25 open for all.

That is a good step. Did you perform the telnet from a local machine on your LAN, the server itself, or from a remote location. This confirms that your server is listening on port 25 but doesn't tell us whether or not your ISP is allowing traffic on port 25. In order to prove this, you will need to perform a telnet mail test from a remote location.

Mr. Noway2
Using telnet to my postfix server on 25 from LAN i can also send mail. But some of mail doesn't sent successfully because of mail.log status is relay=none.
