Hey everyone...

I've got an application by VineyardSoft (KnowledgeSync) running on an application server. It uses IDSMai32.exe or mailbee.dll to send emails from the server, to our "Mailhost Application Relay" receive connector that I have configured on my hub transport server. We've tried using both mail applications included with their software and the problem occurs just the same.

What's happening is that out of say 30 or so batch emails, two or three will be missing the attachment that is supposed to be attached to the email. Instead, an exchange-generated txt file named ATT00001.txt is attached. It happens randomly...sometimes at the beginning, sometimes in the middle (skipping one or two), or at the end.

I've tried a newer version of the mailbee binary, but that didn't make a difference. IDSMail doesn't look to have been updated since 1997. It wasn't doing this against our Exchange 2003 Virtual SMTP server.

Here is a full report on the RC in question:

Well, I think its fixed. My user put a switch in the program which tells it to use authentication, ssl, etc, or not. Originally, there was nothing entered next to the mail name. She put /AUTH next to it and it send all emails successfully. There were no rogue txt attachments.

But why would 2 or 3 out of 30 send incorrectly, with the rest correct? I would think it would be an all or nothing thing. Oh well...interesting.
