Best I can offer you, is, "don't do that".

When you send to a mailing list and to an individual at the same time, the messages do go by different routes within the server. This means that the "duplicate messages" are not really duplicates, and the server cannot throw either of them away.

This is not a defect, nor is it something you can configure around. This is done, so that under no situation will a mail be lost.

There is no work under way to prevent this, either.

Hi,

Can you please supply the FULL email headers of the two copies of the same email that you mentioned.

The differences between the two headers will show where the emails diverged in the email processing and may help to explain why you have a duplicate. As Jay noted, it may be there is no way to avoid this.

Regards,

Shane.
