Hello

I am a networking student. for experiance Iam tryoing to set up a basic
mail server . I have a copy of server 2003 in my text book. and I have
purchased a domain name.
I have added the services requierd to and have set up mail boxes. as
well i have set up mx records a records and dns on my network. I have
access to the server through my fire wall. checked with id serve and
telnet.
IDserve shows the server ready. I have to use dyndns as i don't have a
static ip adress but as i said i can see the server from out side my
network. I have to use port 52525 for incoming mail connections. as per
dyndns.
mail relay.

I don't use dyndns (but I do use a similar service from no-ip), but where
does port 52525 come from? Other email systems will expect to use port
25, which is the standard for SMTP (e-mail). Does your ISP block port 25?
Some do, in which case you are stuffed and will not be able to use your
server to handle incoming email for your domain.

I sugget you change back to port 25. Ensure that everything works
internally on your LAN and only then worry about getting it to work for
incoming emails. Be aware that for outgoing emails you are probably
better off using your ISPs SMTP server because many servers will reject
emails from servers with dynamic IP addresses.

Hope this helps.

port 52525 is one of the ports dyndns say's i have to use. they give
others but not 25. can i redirect there port to 25 ??

If you want external email systems to connect to your local server to
delivery email to you then you MUST use port 25, otherwise it will not work.

Where does dyndns say port 52525 (url please)? If you are using an email
service that THEY provide and pulling down email from THEIR server then some
other port may be required, but only if you are pulling email down from
them. For my server to delivery email to your server you have to be using
port 25 or it will not work. If on the other hand my server is actually
delivering email to a server run by dyndns (which in turn will use port 25)
and you in turn are pulling down email from dyndns then port 52525 might be
appropriate.

Does your ISP block port 25?

What is the domain name you have purchased? (because then I can look-up
where emails would be delivered to)
