(b)SMTP and exchange 2000

Hi all,

I'm trying to configure exchange 2k (part of SBS 2k) for receiving mail via
bSMTP. I forwarded port 25 on my vigor router to the server. The problem is
that although grc.com says that port 25 is open, I still can't connect to
my mailserver with telnet:

bpvw@xs1:~% telnet 213.84.114.69 25
Trying 213.84.114.69...
Connected to bpvw.xs4all.nl.
Escape character is '^]'.
Connection closed by foreign host.

Did you run the ICW-wizard? How many nics in the server?

Can you telnet to port 25 from the SBS server itself?

I did run the icw-wizard, but no change. I've got two nic's. One for the
network (ip server: 192.168.1.9) and one for the router (ip: 192.168.2.10,
router/gateway: 192.168.2.1).

Nope. telnet 127.0.0.1 25 gives a connection to host lost message.

Telnet to your public IP.

Already tried that (sorry for me not being clear):

From an external system:

telnet 213.84.114.69 25
Trying 213.84.114.69...
Connected to bpv.nl.
Escape character is '^]'.
Connection closed by foreign host.

from the server itself:
telnet 213.84.114.69 25

connection to host lost

You better check with your ISP.
Dnsreport is giving the next 4 mx-records to which can't be connected for
some reason:
Your 4 MX records are:

100 mx1.xs4all.nl. [TTL=86400] IP=194.109.6.219 [TTL=43200]
IP=194.109.6.50 [TTL=43200]
100 mx2.xs4all.nl. [TTL=86400] IP=194.109.6.18 [TTL=43200]
IP=194.109.6.49 [TTL=43200]
100 mx3.xs4all.nl. [TTL=86400] IP=194.109.6.19 [TTL=43200]
IP=194.109.6.48 [TTL=43200]
100 mx4.xs4all.nl. [TTL=86400] IP=194.109.6.54 [TTL=43200]

ERROR: I could not connect to one or more of your mailservers:
mx3.xs4all.nl: Timed out [Last data sent: QUIT ]

If you want to be able to receive mail on your IP 213...., you'll have to
ask your ISP to update the MX-records.

Thanks for testing it. Although it would be very handy to have my own
mx-records it isn't really necesarry. My ISP offers batched-smtp which
means it will forward every mail to my mailserver. When my server isn't
online it will keep the mssgs in my mailbox and will deliver them as
soon as my mailserver will be connected again.

The only thing I really need is an open smtp port and a forward on my
router to my exchange-server....well, that's what i thought. I don't
know what's wrong, though. Maybe you're right and I really need an
mx-record. But I don't need that to telnet to port 25, do I? There must
be something else that's blocking it....

Thanks for your effort,

David
