Try telnetting from outside to port 25<br />
postfix -bt is of help to sort out dangerous rules.
</div>


<div>
how do you do that you mean like using putty but instead of port 22 use port 25

I did the above and seems to work fine: using telnet localhost 25; the email was delivered but when I try to send it back to the user it still says: no user here..
</div>


<div>
I realized that if I send an email as : name@<a href="http://www.solunatec.com" rel="ugc">www.solunatec.com</a>:: instead of :: name@solunatec.com; the email does not get turned back; but it also never makes it to the destination on the server....

<div>

Is it entire output, or maybe you deleted some lines? I don't see myhostname neither mydomain options set. I don't see also any virtualdomains (they are not necessary of course). So there is nothing about domains which are treated as local by postfix (but as I checked solunatec.com (you wrote it in one of previous comments) it accepts emails for @solunatec.com).<br />
Anyway - I reread your comment with full headers, and I see something strange (I should notice this earlier).<br />
Email addressed to abelsol at solunatec.com was sent to mail.cobm.net/xterra.websi<wbr />tewelcome.<wbr />com. This server gave you &quot;No Such User Here&quot; response.<br />
So the question is - why this email got to mail.cobm.net instead of your server?<br />
I can see, that MX for solunatec.com is solunatec.com, does your server see the same? Check this with command: &quot;host -t mx solunatec.com&quot;
</div>


<div>
mail.cobm.net / <a href="http://www.cobm.net" rel="ugc">www.cobm.net</a>&nbsp;/ is a site I have hosted right now by hostgator: so I am using them as a mail server; the whole idea is to bring cobm.net to the physical server I am working on now being / solunatec.com; but since I have little experience I wanted to set up solunatec first and later cobm.net becuase on cobm.net people rely on emails etc.....: how I do that switch is another story for later becuase I dont know exactly if I can run mail for both addresses?::once I get this email stuff worked out I am most of the way there...i think..need to set up samba too...
</div>


<div>
I wrote;<br />
www# host -t mx solunatec.com<br />
solunatec.com mail is handled by 10 solunatec.com. &nbsp; <br />
I use dyndns &nbsp;and my mx is simply solunatec.com
</div>


<div>
Two more commands (to be run on solunatec.com) :)<br />
host solunatec.com<br />
grep -i solunatec /etc/hosts
</div>


<div>
dude it works!!!! you gave me an idea: I realize that that hostgator account is an hosting account and solunatec.com was still an account albeit not active; I just removed it and now it works...:thanks ....so much....I love this site becuase of people like you ; you stick with it until one gets a soluntion...

so once again I can send emails out and they arrive at another mail server; but when the other mail server tries to respond the email gets sent back with ; 'no user here' message..; I guess the email cannot get in.; so my question is ; does telnet to localhost to port whatever establish that that port is open or do I have to forward one or more ports like I did with the http port?

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
