Hey guys, I was wondering if any of you know why my 'MDaemon' wouldnt be working :wacko: heres how it goes -

I have sent an email from my my gmail account into admin@218.214.133.17 and it comes up on the 'MDaemon' program as 'SMTP rcvd: 1' ;

But then when i try to download it via Outlook Express with the settings 'pop3.218.214.133.17' & 'smtp.218.214.133.17' it says -

'The host 'pop3.218.214.133.17' could not be found. Please verify that you have entered the server name correctly. Account: 'pop3.218.214.133.17', Server: 'pop3.218.214.133.17', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 11004, Error Number: 0x800CCC0D'

I am trying to receive the email on the same PC the server is running on (if that makes a difference ?) ; Im using my external WAN IP address as I dont have a domain registered (Do I need to have a registered Domain to be able to use this ?) ; I have got Virtual Servers for the POP and SMTP configured on my router ; I am also pretty sure that all the settings on MDaemon are correct :blink:

So yeh if you guys know watsup with my mail server then please help me out :)

:huh: Really, you used these ---> "pop3.218.214.133.17' & 'smtp.218.214.133.17" And it did not work - amazing! ;)

Does in any way shape or form, even if high on crack --> look like a valid type of address to you??

And you get this error --> "'The host 'pop3.218.214.133.17' could not be found" -- Really? ;) who would of thought?

Think about it for a second dude!

edit: your up and running to the outside world:

Connected to 218.214.133.17.

Escape character is '^]'.

220 218.214.133.17 ESMTP MDaemon 7.2.0; Sat, 18 Sep 2004 22:21:02 +1000

And accepting mail;

Escape character is '^]'.

Just think about it for a few seconds - does pop3.218.214.133.17 seem like something that would work to you?

did you open ports 25 and 110 (smtp and pop3) on your firewall?

Trying to send and receive on the same pc? try 127.0.0.1 as the domain.

Yep ports are opened

ports.JPG

Tried 127.0.0.1 & 192.168.0.102 (my internal IP) both dont work

Are you saying that I need a Registered Domain for it to be able to work ? And I cant use my IP address

I saw that now my stats are - SMTP rcvd: 2

POP sessions: 7

before was - SMTP rcvd: 1

POP sessions: 0

:wacko: Is that to do with you testing it ? SO it does work to the outside world ?

No - how exactly do you think pop3.ipaddress would work??? have your ever gotten to a machine using name.ipaddress before ?? No really - amazing ;)

You are up and running on both smtp and pop3 - I even sent you test message, now if you would give me your password, I could check the mail;

Connected to 218.214.133.17.

Escape character is '^]'.

+OK 218.214.133.17 POP MDaemon 7.2.0 ready <MDAEMON-F200409182235.AA3501125MD3502@218.214.133.17>

user Admin

+OK Admin... User ok

pass test

-ERR access denied

Here is another hint - quite a few routers have issue with loopback connections. Ie if your on machine 192.168.0.2 - and you try and connect to the WAN IP address of the router, ie 218.214.133.17 on a port that is suppose to be forwarded back inside the private network. It won't work. But your machine is up and running smtp and pop3 - I have connected to them from the outside.

Now think - your on the machine running these services, and it has an IP address of 192.168.0.102 - what IP address would you use to connect to it? ;)

In Outlook Express if I do this then it says invalid POP/SMTP server or something along those lines :wacko:

Here is what your client should look like;

My website works from internally though (using 218.214.133.17) :wacko: So i was assuming that so would my mail

you cannot use a domain name conjoined with an IP address in a URI, it's either one or the other. instead of pop3.218.214.133.17, just use 218.214.133.17.

You have to set up the 'pop3' alias in your DNS, which would require a domain name. (which can be created in the DNS server in your internal network if you're cheap) but don't waste your time. just use the IP address.

Dude it is up and running, look to see which hosts are allowed to talk to your server. Maybe you only allowed your router's IP address? Double check that you did not typo something. But I connected to it from the outside, and can access mail, and send a message to the admin@ipaddress account.

ooops . . . :cry:

I cant seem to be able to send mail says

'The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was 'admin@218.214.133.17'. Subject 'LOL', Account: '218.214.133.17', Server: '218.214.133.17', Protocol: SMTP, Server Response: '451 <218.214.133.17> is invalid or DNS says does not exist', Port: 25, Secure(SSL): No, Server Error: 451, Error Number: 0x800CCC78'

I am able to receive mail though. :wacko:

As you will soon see - running a mail server on a home type connection is POINTLESS. I normally give that speech right away. There is NOT one good reason to waste your time doing so.

Most machines will not except mail from you without a domain name, and then even if you get that - your IP is a dynamic assigned, and none of the major players will accept mail from you anyway.

You have no redundancy, so to get mail you have to be on 24/7/365, you have to worry about security, etc.. etc.. etc...

:yes: Exactly. And, any server which does reverse DNS lookups (most larger organizations do) you'll be screwed since you're just another client IP in the massive world of spam.

That is, I wouldn't trust email from that IP address with no domain name attached to it.
