Re: wodSmtp.dll and DrWtsn32 (General questions)

Hi Chris,

Is there any chance we could reproduce this? Can you reproduce it at will?

If so, could you perhaps send us a simple sample that we could run on our side in order to duplicate the problem? In that case, you can send sample to techsupport@weonlydo.com

Damba,

Funny you should say that. I am setting up an environment to test that as we speak.

Thanks.

Damba,

I have tried testing in the office and using the company SMTP server and also connecting to the production SMTP server used for our web application. I cannot duplicate the problem myself in a test environment.

However, if I create a large broadcast on the live production system where the SMTP server is on the same machine as the email client, I can cause the problem to happen quickly and not so quickly.

I have found that the normal setting for our application of sending 10 emails followed by a one second pause will cause the DLL to abort fairly quickly with the 750K in attachments (say withing 10 to 30 seconds). However, if I drop the email rate down to 1 email per second, it does not crash for a significant period of time sending the same large emails. It does eventually crash however. Last night I left it running sending emails at around 4 and it was dead by 8. But this sent a significantly larger number of emails with large attachments that normal.

Question: Is there something that the email client should be doing to check if the server is being swamped?

Thanks

Chris.
