Kerio Mailserver 6.3.1
Windows Server 2003
running on vmware
everything using secure because ISP blocks 25
using dyndns.org

I'm very new at this, so please bear in mind that. I've set up Kerio and everything seems to be work. However, I can't receive email. I have a dynamic ip address with a dyndns domain. How do I setup a mx record?

Thanks,
Greg

This is way I was trying to say before I kept editing my post. I'd figure I would have a hard time trying to explain it . . . . hopefully this would work as I'm trying out Kerio (and having problems with this)

1. Let's say <.a.t.>kerio is the Kerio Mailserver and I have pop3 download enabled from <.a.t.>gmail. I write an email (from <.a.t.>yahoo) to <.a.t.>gmail
[img]http://geocities.com/greg_rummel/images/mail1.jpg[/img]


The email gets sent to gmail and kerio downloads the email through pop3 download
[img]http://geocities.com/greg_rummel/images/mail2.jpg[/img]


How here's where it gets interesting, if I want to respond to the email <.a.t.>gmail
[img]http://geocities.com/greg_rummel/images/mail3.jpg[/img]


when <.a.t.>gmail gets, it uses the <.a.t.>kerio address. I want it to use <.a.t.>yahoo, instead of <.a.t.>kerio. Is there a way to do this or is this impossible?

If the above is impossible, could someone point me to how to set up a pop3 on my windows server 2003 and have a mx record on dyndns. I have to use dyndns as I have a dynamic ip address and the ISP doesn't block port 110.

Hopefully this won't confuse people even more

Thanks for the advice,
Greg

Do you mean your ISP blocks port 25 for incoming SMTP? Then there is no way you can receive mail, even if you switch to Secure SMTP.

I'm out of ideas now . . . .

I have a mx record on my domain, dns stools sees that I have a mx record, but can't connect to the mailserver. I have an A address as well. Any ideas?

Thanks,
Greg

You seem to have misconfigured your DNS. You have a CNAME record pointing to itself. dnsstuff.com says:

Quote:

One or more CNAMEs were encountered. gregschultz.net is really gregschultz.net. [gregschultz.net->gregschultz.net->gregschultz.net->gregschultz.net- >gregschultz.net->gregschultz.net->gregschultz.net]


You must change your DNS record at

ns2.editdns.net

There's no point setting up DNS, CNAME or MX records if your ISP blocks port 25. You won't be able to receive mail. Even "secure SMTP" uses port 25.

Even if I change ports I won't work? . . . .

No. Port 25 is reserved for SMTP, and is defined in the SMTP specs/RFQs. SMTP servers will send mail to port 25 regardless of what you have set up, so you won't be able to receive mail. There's no way around that. Even delivery won't work, as your server will need to deliver to other servers on port 25, which is blocked.

The only possible way to get or send mail on a port other than 25 is if you have a relay server accepting mail on a port other than 25 for your outbound mail, and that will allow you to specify another port for delivery to your server. Even that may not work with a dynamic IP, as some servers require entering the IP address of the final SMTP server and not the hostname.

bummer . . . oh well, no big deal. The only reason I was trying to do this was to have push mail on my pda. I've found a way to do what I was trying to do earlier in the post.

Thanks everyone for the help,

Greg

i am having the same problem the guy you were helping has. I have a static DNS through dyndns.org (myname.dyndns.org). My ISP blockes everything but their own traffic on port 25. Like you suggested I set my SMTP to relay for out going messages to my ISP's SMTP, and it goes fine. But i still cannot recieve mail even tohugh i have set my SMTP to lisiten on ports 26 and 27. Please advise. Thanks in advance.

log into webmail and click settings. click on the "mail" tab and enter the email address you want to use as your response in the "default from address". I use <.a.t.>gmail.com for all of my responses and I have pop3 download from my <.a.t.>gmail.com account.
