E-mail applications
We are use a NT4 server, which is a PDC with an Exchange 5.5 installed. We find that the email in the outbound queue are still exist even it has already sent out. Once we restart the IMS, those mail are sent out again. sometime, it can stuck ove 10,000 mail in the queue can not be clear. is there any solution to solve this problems?

Thanks. We'll let you know when a new response is added.

First off, running Exchange on your PDC is a big No-No! It is highly advisable that you get a dedicated server for Exchange.You will save yourself a lot of aggravations in the long run!

As for the IMS queue issue, how long has this problem existed? Is this a new install or one that has been working correctly up until recent? Have you made any changes to your server since the last time your IMS worked correctly? Do you experience problems sending messages to local recipients or just with Internet mail? Any trouble recieving messages from the outside? After restarting the IMS and clearing the queue, have you confirmed that mail is getting to it’s destination? Maybe send a test message to an Internet mail account (AOL, Hotmail etc.)to confirm your mail is getting to it’s destination.

Though rare, I have heard of anti-virus software causing very similar problems as your describing. If you are using anti-virus on this server, check your software settings to confirm that nothing is blocking outbound traffic on port 25. Otherwise, you may want to confirm config settings for your SMTP and IMAP services as there may be something that you have overlooked. Wouldn’t hurt to check your POP3 services as well though POP3 is really for receiving Internet mail and not sending. Probably wouldn’t hurt to check your DNS and firewall settings as well.

This should get you started. If the problem still persists, update your question to include better detail of what exactly is happening as well as any actions you have already taken. The more info you can provide, the better your chances are of getting help!

Good Luck!

    while most exchange 5.5 support is gone here is a good website http://www.microsoft.com/technet/prodtechnol/exchange/55/library/default.mspx I seem to remeber a problem with the information store that is fixed by using a repair utility. it has been so long singe i used 5.5 i cant really remember. the following web page has the info you need. http://www.microsoft.com/exchange/techinfo/administration/55/database.doc If you are not going to upgrade a 2003 domain i would suggest upgrading to 2000 server and exchange 2000. just bring up a win2000 member server, install exchange 2000 and join it to the existing exchange site. then move your users to the new server and take the 5.5 server out of the site. Good luck Matt
