Your IP is blacklisted. There could be many reasons. If you're using many ISPs, and just setup your server with dyndns or something similar, many times such mail will be blocked by default, especially as it will be known to be a dynamic address.

One fix that sometimes works is to set your ISPs smtp host as a relayhost in postfix.

relayhost = myISPs.smtp.server.myisp.com

Some ISPs allow that, others specifically prohibit it.

[jaysel]

thanks sir scottro for the fast reply.. Well that's a relief. I've already suspected that it is blacklisted well anyway are you talking about the DynDNS.com?? Ohh men I really need to learn more about linux. Sir scott what do you thins is the best linux distro for a mailserver?? For some reason my fedora 11 wont properly restart when i reboot my system it is just stuck with the "restarting system" display.. I don't know if it's my downloaded fedora or simply the fedora distro

[scottro]

Really any distribution can run a small mailserver with postfix as you're describing.

As for the F11 restart issue, that sounds as if it should be another thread. Did it restart properly in the past? Did this happen after an update? If it's hanging like that, sometimes, for whatever reason, you have to do a hard reset, that is, hold in the powerbutton till it restarts--that's always a VERY last resort, of course.

[jaysel]

Okay sir scott then i'll stick to fedora. BTW are you referring to dyndns the free ones??

Ooops sory for the OT F11 issue.. Yep I do a hard reset everytime I boot so I just shut it down not restart anymore to prevent corruption. I have an update from F10 to F11 and it works great but the F11.iso that I've downloaded seems to have that problem well anyway I'll put this one to another thread. Sorry for the OT

[scottro]

Yes, I'm talking about the free service. There are many like that, where they give provide something like yourname.homeunix.net or whatever, so that you can reach your machine from the outside world.

By the way, you don't have to say sir scottro, just scottro (or Scott) is fine. (I realize you're trying to be polite, and I appreciate the effort, but in English, it's almost too polite. Thank you for the consideration though.)

This url below may help you with more information from SpamHaus, and it should have a link to remove your IP if you have a static IP from your ISP.

[jaysel]

okay scott thanks for your help and to neo my problem is already resolved. I already have it unblocked to spamhaus but still can't send messages to google don't know what else to do.. Does it have someting to do with reverse DNS I Believe this is the solution to my problem but I'm no expert and i'm having problems understanding DNS config.

[neogranas]

It may, but I'd also ensure you have an SPF and TXT records on your domain. Those can go a long way with some companies.

[zackf]

I think what scottro is saying is not dyndns related, but you can change your outgoing server from yourself to that of your ISP if they allow it. Maybe even something like this:

jaysel it is true that google checks revDNS i had problems with it too. But really it shouldnt be your problem to set that up, in my case ISP is setting revDNS, you just have to contact them to have it done.
