UM 4 will only send 4 mails

When checking UM4 it appears that it will not send more then 4 mails out of a recordset with 1337 addresses.

That seems odd... does your ISP have a limitation you might be exceeding in terms of emails per second or something? Have you enabled email logging in a database or tried looking at the generated error report from the bindings panel? Those are both really useful tools for investigating issues.

When doing mass emails like this, it is really helpful to use the email logging feature. This way it will record all of the emails that do and don't go out. Then you can remove the email addresses that have been successfully contacted in further attempts to prevent repeats when a failure does occur for some reason.

I just checked. It will just send 1 mail at a time
I have attached some screendumps for u to see

I have created a support incident for you... please update it with a phone number and I will research this problem with you directly.

It may be a problem with the recordset filter. Are you sure it is actually returning all of the results properly?

Yes, the recordset is returning all mailaddresses correctly.
Just when I tell it to create the log table for me as in img>error4, I get an error message as seen in error1

Please update your support incident with contact information and I'll call you to look into this directly.
