not reciveing mail

[ekke]

Hey
I had a 2003 mail server that worked just fine
and after we shutdown the server an moved it to another location and change the mx record with my isp it will not accept incoming connections on smtp, we have the same firewall beacuse we moved the entire office.
i can send email just fine.
its driving me crazy.
please any ideas would be greatful

Have you tried telneting to port 25 directly at the DNS name that the MX record points at? Or try directly at the external IP? You need to sort out whether this is a DNS issue or an issue of your server actually refusing connections. This will help you sort that out.

From outside the firewall, can you telnet to the Exchange server over 25?

Sure you have the same firewall, but did you change the firewall settings to forward from your new external mail IP to the server?

Ekke, you've shown that the issue isn't your server, but by doing it inside, you haven't found anything out about DNS or your firewall. Doing the test from outside will tell you about those things.

Check your firewall rules, like Sean said, and make sure that your SMTP rule isn't using old IP addresses.

hey
i have never been able to telnet to the server from the outside beacuse authentication security.
i have set up several exchange server all the same no telnet on port 25 and are working fine.
the firewall is a simple one the server has the same adress on the inside as before. the rule is simple, forward port 25 the the servers internal adress.

Ekke, how do public SMTP servers deliver to your server if you are using some sort of authentication security scheme that blocks telnet on port 25? Telnet on 25 shouldn't be any different than a standard SMTP connection if you pass it the right information. Am I correct? What am I missing?

I've reliably been able to test SMTP connectivity using a telnet client to port 25 on any functional public SMTP server I've pointed at for the last seven years. Maybe I've been lucky.

along with MX records reverse DNS entry on your ISPs DNS server will help as well name resolution as well...

"i have never been able to telnet to the server from the outside beacuse authentication security."
-then you will never receive mail.

if you need tests post your domain name or IP

All the best!

I'm with ShackDaddy - how are you receiving mail if you're using some sort of authentication? SMTP is anonymous by design. Even if your firewall is a proxy to the mail server, you should still be able to telnet to it over 25 and send a test message.

thanks for all the replys.
after almost F...ing everything up
i got this message.

This is an SMTP protocol error log for virtual server ID 1, connection #1. The remote host "*.*.*.*.*", responded to the SMTP command "xexch50" with "504 Need to authenticate first ". The full command sent was "XEXCH50 1820 2 ". This will probably cause the connection to fail.
