dyndns - success

[dwmtractor]

Hey ejecthunter,

I'm afraid I won't be much use to you; as I said to the other poster, I haven't actually set up a DynDNS -based Zimbra myself, I merely pointed out those wikis. All my own Zimbra work has been on static IPs. I will warn you, based on the experiences of others I've read on this forum (and on my own spamfighting experience) that even if/when you get Zimbra up and running, you may find that some portion of your email gets blacklisted simply because the personal broadband account ranges are often blacklisted by other spam filters. They do this because so much of the SMTP traffic from those IP blocks comes either from deliberate spammers, or personal computers infected with spambot trojans.

Anyhow, while your mileage may vary, you should be aware of this as a potential issue. That said, I know there are people out there who use Zimbra on dynamic IPs and are happy, so I don't mean to discourage you from trying.

As for paying for a domain, you mentioned

i am willing to pay for actual domaain like EJECT.COM but have no idea if it will have those MX records or whatevers needed to run a mail server.

By default, a purchased domain will have none of the MX "or whatevers." Your MX record is set up in your DNS--as are reverse DNS records and the like--and you may or may not get DNS services from the registrar from whom you buy your domain (if you do, you'll likely be paying more for the DNS service). I get my DNS hosted by the provider of my static IPs; others host their own authoritative DNS server, still others host their DNS records somewhere else. The only thing that matters from that point, is that your domain record (which you'll update with the registrar where you purchase the domain), points to the appropriate DNS server (nameservers). Those servers then hold the rest of your records.

Now, does DynDNS provide MX and Reverse-lookup services on their accounts? Yes, according to their website, they do. How well does it work in a hosted-mail environment? I don't know. I suspect it could be a bit of a problem if, for example, your mail is sent from one IP, and then some time later a spam filter does a reverse lookup on your domain and gets a different ip, therefore classifying your message as spam. But this is all theoretical, I do not know in practice because I've never tried it.

I hope this at least helps you to get going in the right direction. Perhaps other users who've actually tried dynamic IPs for Zimbra can give you better tips.

thanks for the detailed explanation, i now understand a bit better...and actually i have a static IP...i only the dydns to point the eject.mine.nu to my IP,

might the above help better>?

Well, sure, this at least means that my worries about you getting lumped with the spammers for a shifting IP should not be a problem. But again, you'll have to set up the MX records on DynDNS; those will not happen automatically--with any hosting service I'm aware of, anyhow.

Outbound mail is really the only concern if you want to purchase your own domain and use Dyn-DNS to keep track of your IP. That's what I'm doing at home and haven't had a problem thus far. Make sure that you point your domain's MX record to the A record of your Dyn-DNS address (don't use a CNAME for mail.domain.com to point at it).

Once your MX records are in place, you'll want to make sure you either can get a static IP for sending out mail or just use your ISP's mail servers (if they allow). I've been sending out that way at home for months with no issues. Outgoing SMTP Authentication - Zimbra :: Wiki

many thanks tractor and Y@w, i am about to setup the emails. is it possible to give me a example of what to put in the MX record feild, as everytime i try it keeps saying something about being AAAA, my current domain is http://eject.mine.nu some working example of this would be highly appreciated.


ok i also tried this "eject.mine.nu 43200 mx10 mail.eject.mine.nu" (without quotation marks), in the feild but it says need a valid host name...


any help is appreciated

regards

Doing a dig on mail.eject.mine.nu doesn't return a result for me which would explain the invalid hostname error. A dig for eject.mine.nu did return as a valid A record. I'm guessing you want just eject.mine.nu for your MX record.

sorry, again i will make the noob remark...hmm idont really understand the workings of the MX record so can you please tell me what to put in that dynds feild so that it will allow mail.


thanks again

In the screenshot that you posted, the software is looking for the A record of the host that you want mail to your domain to be sent to. There's plenty of good reading on MX records out there: MX record - Wikipedia, the free encyclopedia

ok i just figured it out, the feild which i was so focused on in the previous post is actually irrevelant. after seting up my zimbra... as per following config,

webmail MTA hostname : localhost
webmail external port 25
relay mta for external delivery is mail02.hgcbroadband.com (MY ISP)

so i used zimbra to send a test email to my gmail account and it was received.
but when i replied it wasnt recvied by the zimbra server.

also i have tried connecting to pop.eject.mine.nu using outlook but that didnt work either...

ahh also i have check my ISP they say that they have blocked my port 25, so is there any fix for that?

kinda stuck inbetween then now.

any help is appreciated.

regards

You'll find that dynDNS (and others if you search the internet) has a mail relay service that will accept mail and relay it to your server on a different port, the only drwaback is that you'll most likely have to pay for the service.
