There are daily more 'Guests' than users flying thru. They only can vote, when they register. I would appreciate more voters, too ...

How would you have a dynamic IP running on an e-mail? You couldnt really assign a domain that kept pointing to your IP if your IP kept changing, could you? Wouldnt your e-mail would be like me@66.66.666.6 one day and then you would have to create a new domain full of e-mails like me@55.55.555.5 the next day?

There is nobody on this forum. There are 2 admins who awnser questions, nobody else is knowledgable or awnsers questions. People register on this forum, ask one or two questions, and never return. As for me 2 admins, who i'm sure have other things to work on, is not a large enough pool to make the sevice fast in my humble oppinion. I've had posts up which the admins skipped to awnser a more recent question, and didnt awnser my question until 3 hours later.

Wrong. You can run xmail with dyn IP. That's why there is option in the server.tab file for dyndns.

Posted by: tac Jun 3 2004, 03:39 PM
LOL, how can i be "wrong"? i asked a question. I was looking for an explaination from someone, and i guess you sort of provided me with one. But how does DynDNS work?

You can. See e.g. http://no-ip.com ..

You create an account at www.dyndns.org site and then you can create for FREE up to 5 domains (3rd level ones). To keep them updating you ip you can use several tools which you can find also on their site.

Wow....

1) Are you paying for this?
2) How much did you pay to use this?
3) What kind of investment did you put on this software?

The answer is nothing.

Support? *FREE* SUPPORT? Priceless

As a ten year old would say - STFU N00B!

If you have broadband, technically your ip address is dynamic but mine has only changed twice in three years. DynDNS.org hosts my domain and I have software that updates the CNAME and MX records at dyndns within 5 minutes of the ip changing.

So YES you can run mail behind a dynamic IP.

I got dynamic IP. Every connection I got other IP. Every 10 hours i'm reconnecting (& get new IP) by ISP. I got 2 domains from no-ip service. Xmail work great with them. Everything works just perfectly smile.gif

why still use a dynamic IP address when you can keep your IP static for years...as long as your router and connection out to the net aren't powered off at the same time...most routers or hubs will keep the ip address for eternity...i'm also fairly sure that there are companies that provide you with Dyn-DNS services when you buy their routers!!! smile.gif i don't see why anyone would run a server with a dyn-dns when you can easily and cheaply keep your ip address? of course, i'm assuming that nobody with a dial-up connection is hosting a mail server blink.gif

Posted by: hschneider Sep 17 2004, 12:04 PM
Looks like there are many dialup users. There are many countries where a leased line is either nearly unpayable or unavailable. Other reasons are e.g. serving a mailing list or private system to save provider costs.

This is not true. If the IP address is assigned to you, it's still a DHCP address no matter what. A static IP is assigned to you by the IP block owner, is not part of the ISP's DHCP scope, is an IP that just can't change, and is manually entered into your stack. The reason that most people hang on to they're DHCP IP address is because of poor DHCP manangement on the ISP side. They're not managing they're leases very well, that's all.

If you have an RFC2132 compliant device it will listen to the lease time and release the IP as told. A perfect example is any of the NetScreen (Juniper) firewall's running PPPoE... the 5 series especially.

Now on the other hand, I run a http://www.smoothwall.org (Linux Based) in front of another firewall (tiered architechure) because the SmoothWall will ignore the lease time given from the DHCP server. It will hang on to that IP address forever UNTIL the ISP decides to reclaim it. They have every right too and it can happen since I don't have that address statically defined in my IP settings. If they do reclaim it, I just run a cron job every 15 min to connect to my ZoneEdit account via lynx and update my Dyn-DNS that way.

If you take that IP address that they assigned you, put it manually in your IP stack, and they try to reclaim it... you're going to bust yourself out because your now in violation of your EULA (like most of us aren't already!). They'll pounce on you in a heartbeat and strip your service. That shouldn't be needed since there are plenty of workarounds.... example.... Dyn-DNS!

Just my 2 cents.....

Thanks Rog_G for valuable background info.

master.gif Hi ! I recently put a new Xmail v1.20 svr online in our small company. We use ADSL, and our domain (.com) is dynamically updated at DynDns.org. The server is (as you know) very strong.
BUT, our main problem is the anti spamming overal system: many lists show us because our IP is in the "dial-up" range.
All test Iīve runned against our server were successfull, but this problem is very hard to handle.
So "Dynamic or Static?": it seems the System is not perfect enough today!

Posted by: hschneider Oct 27 2004, 06:31 AM
The prob here is the anti SPAM policy of some recipient servers, including AOL and other huge providers. The only solution is to forward outgoing traffic to your ISP's SMTP.

Posted by: sergioperr Oct 27 2004, 12:43 PM
master.gif I agree, but I couldnīt find a way to forward to my ISP smtp only the EXTERNAL traffic, because as I understand, If I configure that so every internal mailbox 'must' (accordingly to Davideīs readme) autenticate to the ISP server.
Is it true? Anybody knows how can I forward only external traffic?

Posted by: hschneider Oct 27 2004, 03:15 PM
If your local domain is named different, XMail will only forward outbound messages. Use smtpfwd.tab for this.

Posted by: sergioperr Oct 27 2004, 03:47 PM
master.gif Thank you for your support.
Iīm trying right know.
But, what about SMTP autentication in my ISP server? I canīt find a place to put our username and password.



Posted by: sergioperr Oct 27 2004, 11:57 PM
master.gif OK, OK !!!
I found it !!!
Itīs all right !!!

Fine - to complete things:
/MailRoot/userauth/smtp/name_of_isp_server.tab

Rest see manual.

Why shouldn't someone with dialup run a mailserver? There's a lot of people who do just that - including me.
BTW: The existence of DU-Blacklist shows that DU-Mailserver *do* exist ;-)

I am in one of those countries where it costs a bundle to obtain a fixed ip. At the same time my ISP did me a great "favour" by blocking SMTP traffic (at least on port 25).

I am also with DynDNS (with my own "custom" domain). In order to receive mail I had to purchase their mail-relay package and got my incomming mail going yesterday.

My outgoing mail is pretty limmited by my ISP as well (size and number of addressees - 20 max). I am in the process of trying to configure X-mail to use DynDNS's out mailhop service. That requires SMTP authentication on the remote server. Unless someone can tell me an easy way to configure, I will have to go in the deepend and figure that out in the morning.

Well there is a free service at rollernet.us for redirecting mail to a nonstandard smtp port. And I mean it is really FREE. I use it but for MX backup.

for dynamic users i got a cupple top level domains and if i called my isp i could get it changed everyday but i am mostly static smile.gif, but i bought my domain and set it up on everydns.net and i have my computer update the ip every 10mins running there easy to use script for dynamic people and i just cname *.domain.com to the dynamic a record so when i get a new ip it auto updates smile.gif

I have 5 statics, one for many servers that I have runing. I host my own dns, apache web server, MySQL database server all one Fedora Core linux box. I have FREEBSD box I built to host my ns.1 dns server then I have friend that does ns2. for me I do the same for him. Then on the FD box I have ns3 for backup. I used to run my email on a winblowz box. Then I found Xmail ( It ROCKS ) Now I host xmail on the FD box ( Fedora Core box ). So I am not depenant one winblowz box that has to be rebooted ever so offten and might fail for a number of reason's. My FREEBSD box uptime is as follows.
11:24PM up 287 days, 9:01, 1 user, load averages: 0.08, 0.04, 0.01
