Hi Sergey,

Just for curiosity.. Maybe you have seen something like this before.. Some months ago a client of mine ask me to create a routine to send some celebration bulletin for his company.. I wrote a program very similar to that one of Marc, little difference was in the scan/endscan on his clients table.. And, as result less than 15% of total of his newsletter got the destiny.. 85% return for his email account as undelivered message..

Almost one hundred and half thousand of address was in the total.. All the email address was sign by his own clients.. And, the possibility of errors was minimun..

After this I wrote a routine on PHP to run the same idea on his server and almost all the message got the destiny..

Do you know any limitation for CDO on procedures of mass mailing ?

Thanks

Claudio
