First thing to check: can you telnet port 25 of your exchange server from the outside?<br />

</div>


<div>
from outside of my network? or outside of my server?
</div>


<div>
how do i do that? I ping mail.mydomain.com and it did not reply
</div>


<div>
From a command line window, run:<br />
<br />
telnet mail.yourdomain.com 25<br />
<br />
You should get something like:<br />
&nbsp;220 mail.yourdomain.com Microsoft ESMTP MAIL Service, Version: 6.0.xxxxx.xx ready at &nbsp;Wed, 10 Aug 2011 7:33:04

<div>
it said it could not connect but I do use appriver as my spam filter and I believe I only accept mail from them.
</div>


<div>
make sure the receive connector is allowed to receive email from anonymous and not just authenticated users.<br />
Also see if you can send email internally.
</div>


<div>
I can send internally, where do i check the recieve connector?
</div>


<div>
Yes, do check if you can send mail internally.<br />
If you can, I would also check with appriver tech support if everything looks good from their end.

<div>
I just had alot of test emails show up all at once. I changed the recipient update service back to my old server and i may be back to waiting 30 minutes for incoming mail to come in. everything worked until I started this migration. How do I figure incoming mail to my new server.
</div>


<div>
I called appriver, my spam filter service and they said there was about 8 emails that are backing up the queue and getting disconnected because my ASA 5505 firewall has mailguard enabled. Does anyone know how I can disable mailguard through the ASDM on my ASA 5505 firewall?
</div>


<div>
that did it, I disabled mailguard. thanks everyone for your help

IT Administration is the processes and best practices for programming and development, and incorporates methodologies for managing activities and projects. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, extreme programming and various types of agile methodology. The life-cycle "model" is a more general term for a category of methodologies, and a software development "process" a more specific term to refer to a specific process chosen by a specific organization.

IT Administration

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.
