Email Program [modified]

I notice that when you catch any error you merely exit from the subroutine. This is extremely bad practice as it means you just eat any exception that occurs rather than using the information provided to diagnose why your code is failing.
The best things in life are not things.
As I already said I traced the code it is not throwing any exception. The best practice is to write a logfile. I agree with you.

Is it always (mainly) the same message to the same address ? If your code is not throwing any errors, the most likely reason for the message not arriving is not your code. You should test the app by adding your own address to the BCC field, and see if you receive the message. And/or you may want to look into the following things: 1. the recipient's address has changed or has been deleted, and your app is sending the message to the old address. 2. the recipient's email program has interpreted the message as being SPAM, and is now blocking it. 3. the recipient's email operator uses a (new) SPAM blocking service, which has interpreted your messages as SPAM and is now blocking them. 4. the mail server you send messages through has changed (new server ?)
My advice is free, and you may get what you paid for.

It is not the same message but it is a report in the same format. and to the same address. I just now tried by including my address in BCC but still I did not receive the mail. The mail server has changed 2 months before. Even after changing the mail server the program was sending mails properly and suddenly 1 fine day it stopped sending mails. Subject is same to the mail and also the sender address is same. So if suppose it is identified as SPAM by the server how can we resolve this. As the program is not generating any error logically it seems to be a problem at mail server level. How to resolve this?

The first thing you could try is to manually create a similar message in your regular email client (same recipients including yourself, same subject, same body text, same attachments). See if that message does arrive. Another thing you could check is the Sender address (the From field). Does this address exist ? If the manual message did arrive, was the sender address the same as the one used by your code ?

Manually I am sending the similar message from my outlook account and the message is arriving. Sender address exists.

We are using MS Exchange Server ver 10. Has it got something to do with authentication. If so how to set it using CDOObject?

One last thing to check: on the last day the message was sent successfully, or on the first day the message was no longer received, were there any Windows, MS Exchange, or MS Office updates installed on the sending server ? If so, you can try uninstalling any or all of these updates. I am afraid that after that I am running out of ideas and I have no experience with CDO, and all similar code that I have ever written is in VB.NET. So the only other thing I can think of is to rewrite the app in .Net so you can get better feedback on the reason why the message is not arriving. .Net can give feedback on the
Sendmethod, so you can find out what the smtp server is saying about the message. Good luck, JohanMy advice is free, and you may get what you paid for.

Even we thought the same and written a program in .NET which is working fine. Thank you for all you advices. Regards, Uma
