someone must have a dynamic IP out there!!

[cotfessi]

I'm trying to read all the f***ing manuals that I can get my hands on. Everything I've found thus far has produced a solution for something similar but not quite for my situation. I've posted questions here as well and have not really come up with any responses on both this section and the networking section.

Does anyone out there have a dynamic IP addressed box to which they have a domain name registered and pointing to with the help of a DNS service like centralinfo.net???

I have all of this stuff in place, but I'm confused about my email, more specifically exim on debian, and how it handles my domain name and if there is anything special that needs to be done to facilitate the use of exim so that someone could send a message to user@mydomain.com and it would eventually find its way to my server??

Please help!!!

You have to set up a MX handler for your mail to work. I'm not sure how you do it either because I'm not familiar with any of those Dynamic DNS things.

What I do know is that www.easydns.com (http://www.easydns.com) lets you set the MX and other things like that, but for a fee.

A DNS server is used to resolve a hostname to its IP address. If the IP address is dynamic, then the DNS server must be updated with the new IP address of the hostname; this can be very inefficient. The reason why IP addresses of servers are usually static is to avoid the hassle of constantly updating DNS servers.

If you register a Domain Name you can usually have it hosted at an ISP for a small fee. If you have lots of money you can co-located your own server at an ISP instead. Normally if you are hosted at an ISP, they handle your email for you and you retrieve it by accessing youremail@yourdomain.com at the pop3 server located at mail.yourdomain.com If you are co-locating then you will have to setup your box with an email server, set-up your accounts, set-up your web server etc.

It sounds like you are trying to setup your own server using a dynamic IP and you are trying to setup a domain name where the DNS is dynamically pointing to your server; this is more trouble than it is worth.

The easiest solution, is to have your domain hosted at an ISP. If you plan to serve more exotic services and have more control, then you may have to co-locate.

Good Luck!

go to www.darktech.org (http://www.darktech.org) and sign up for dynamic dns. mine is manualoveride.darktech.org Then download an update client. They have several listed, but I find BBsIP by que two to be the easiest. run this periodically, or set it up as a cron job.

If you want to be able to recieve mail at user@your-domain.org, sendmail is probably the easiest way to go. to see how to set it up, type: man sendmail

i had email trouble with that setup the first time i tried it also, cotfessi

most likely cause is as osnap says, do you have 3 entries into your dns manager at centralinfo.net?

mine is like this

sub domain type points to
www A mydomain.dyndns.org
@ A mydomain.dyndns.org
@ MX mydomain.dyndns.org

if you have that all set, then i don't know what else to try. i never used that mail prog you are talking about, so maybe it would be specific to it and not the domain/network setup ?

i am trying to get my server set back up that way this weekend, if i get it working or have similar problems, i will re-post

thanks for the posts! I checked with centralinfo.net and I do have all of three of the entries in my dns manager. I'm going to setup my mail shortly and will hopefully have something to post in the "How I did it!" section...

i wrestled with this last august/september, so it has been a while, my memory sucks

did you try sending to foo@mydomain.dyndns.org vice foo@myrealdomain.com ?

seems like when i couldn't get what i really wanted (foo@myrealdomain.com) to work, i was first able to get foo@mydomain.dyndns.org to work, then after futzing with it for a while it worked right

i will look for you experience when i go to do mine over the weekend

good luck! http://www.linuxnewbie.org/ubb/smile.gif

Yeah, don't listen to them, they're crazy. I have a domain name resolve to a DHCP assigned IP address. My ip hasn't changed in, uh, a year and a few months, I think. It's really nothing big.

The mail server should just be setup to accept stuff for whatever your domain name is...
