Hi,<br />
<br />
Try to perform telnet on the smart-host IP &amp;&nbsp;Port no see if you're able to connect it. If you have installed Antivirus on the Exchange server recently or made any changes try to disable it for 5 minutes &amp;&nbsp;see if email flow is getting resumed.<br />
<br />
Thanks<br />

Hi,<br />
<br />
have you contacted ISP, or who ever is owner of SmartHost? Usually when I had problems of that kinde, and I was using ISP as smarthost, it was on their side.<br />
<br />
Have you tried with restart, if possible, either server or transport service..<br />
AV problems, firewall, smarthost changed ip address?<br />
<br />
Regards,<br />
Ivan.

<div>
Smarthost is a Win Server 2008 service.<br />
<br />
I tried connecting with my Outlook and mail was sent fine.

<div>
I was able to fix it.<br />
<br />
The transport database got corrupted:<br />
&nbsp;<br />
To delete the specified database and corresponding transaction logs, follow these steps:<br />
<br />
Verify that the Microsoft Exchange Transport service is stopped. <br />
Delete the specified database files and the corresponding transaction log files. The database files and the transaction log files are described in the following list: <br />
Mail.que or IpFiltering.edb The main database file<br />
<br />
Trn.chk The checkpoint file<br />
<br />
Trn*.log The transaction logs<br />
<br />
Trnres*.jrs The reserved transaction logs that serve as placeholders<br />
<br />
Temp.edb A sample database file that is used to verify the database schema. Although this is not a transaction log file, it is always kept with the transaction logs.<br />
<br />
Start the Microsoft Exchange Transport service. If the message queue database or the Content Filtering database does not exist, a new, empty database is created. If the message queue database transaction logs or the Content Filtering database transaction logs do not exist, new logs are created.
