wknight40 Posted November 16, 2008 CID Share Posted November 16, 2008 Alot of POP servers reject SMTP request's from privat/home IP addresses. may not be the problem you are having but it's a thought. Link to comment Share on other sites More sharing options...
zalternate Posted November 16, 2008 CID Share Posted November 16, 2008 have you tried to use port 587 instead of port 25... http://www.pcmag.com/article2/0,2817,1838667,00.asp http://www.oit.ucsb.edu/CHSI.asp Link to comment Share on other sites More sharing options...

That is something your ISP does. They will only allow mail to be sent through there mail server when on there network. My ISP does the same thing, but I was able to get around it by using a different port for my SMTP server. Link to comment Share on other sites More sharing options...
cbtshare Posted November 16, 2008 Author CID Share Posted November 16, 2008 ok thank you lewis, I tried using port 587but now it wont accept or send mail either.I am using 2003 Exchange as stated, is it as simple as going into the default virtual server , clicking advance and changing port 25 to 587? Also is it that from you are receiving mail, its fair to say that port 25 is open, even when you cant send out?(I just dont want it to be that I didnt open the port correctly) Link to comment Share on other sites More sharing options...
Swimmer Posted December 1, 2008 CID Share Posted December 1, 2008 I am not sure if this is still an issue.. I did some MX background searches... you do not have a MX record currently.. at least that I can see. MX Lookup Test E-mail tested: [email protected] Test performed from: Seattle, WA Test performed at: 2008-12-01 11:44:59 (GMT -05:00) Known MX records: Error:No MX records found.

NobleScarlet Posted December 4, 2008 CID Share Posted December 4, 2008 Did the service provider give you any instructions on how to set it up with other mail clients? It could be that you are not using the settings you are supposed to use. Just a thought. Link to comment Share on other sites More sharing options...
Swimmer Posted December 4, 2008 CID Share Posted December 4, 2008 It is a relay issue.. Sorry I was pretty busy today. That could be a possibility however, you shouldn't need an ISP relay server to do this. The only thing that I can think that it would be is a DNS issue.

Swimmer Posted December 5, 2008 CID Share Posted December 5, 2008 It wouldn't be your DNS issue.. Does the server resolve domain names? Link to comment Share on other sites More sharing options...
cbtshare Posted December 5, 2008 Author CID Share Posted December 5, 2008 yea it does, but just so that I can show you how would i go about proving that?I've done this setup a couple times where the server doesnt have a static IP , but it has root hints configured with public DNS ip's as well.

Swimmer Posted December 5, 2008 CID Share Posted December 5, 2008 Alright... a little update at to where this issue stands, for those who are interested. First the exchange server was missing an SMTP connector that would work correctly with the Internet. The easiest way to solve this issue was to use the Internet Mail Wizard.. This enabled the server to lookup up the domains via DNS and send them on their way. Next was the issue of the ISP. Inbound SMTP is allowed however outbound SMTP via port 25 is not. Therefore what we are going to try next is using the ISPs mail server as a relay host. I have done this in the past with Comcast.. however, I am not sure how cbtshare's ISP has their mail server configured... Meaning that they may or many not forward mail from any other domains through their servers. Link to comment Share on other sites More sharing options...
