I have been using a functional mail procedure for over a year, but when I added an attachment function, the attachment get to some but not all of the mail receiptants. The normal mail procedure send 13 messages to 100 addresses in groups of 8 BCC addresses
per message. I do not get any smpte error message. All 100 addressee receive the message, but some receive a valid attachment while others get the message but the attachment is not coded properly and cannot be downloaded correctly. Has anyone had such a
problem?

Thanks, but I dont think the problem is in the code. If I send the attachment as a single or even a three address message, it goes through correctly every time, but when I send 13 messages of 8 addresses each, some get it and some dont. I think I am overloading
the process somewhere in the mail server. The attachemnts come across, but they are not readable (they get the message when they try to open it "This attachment cannot be opened as it was not coded properly"). This leads me to believe that somehow I am overwhelming
the server. Maybe a short one or two second delay between each of the 13 messages is in order, but I dont seem to find any usable code beside using "timer" for providing such a delay. Any suggestions?
