Topic: Multi Drop Email - Duplicates Recd

[brucep]

Installed V9.0, using multi drop email option. Any email that is addressed to 2 or more recipients comes twice (or 3 or 4 times if it goes to 3 or 4 addresses) Other than this strange email error server is working well. I have seen warnings on using multidrop and don't get the error emails and have used multidrop on V6 with no issues - so don't know what to try now - any assistance is appreciated. Thanks

You need to study the full headers of the message you receive and set up a suitable 'sort header' which will identify which copy should have been delivered to which recipient.

I have tried sort headers such as "Received" "To" "For" but with no success.
Here is a header from an email with 5 recipients - Does this show what I should be using as a sort header. Thanks

I don't see any header which indicates which of the five recipients this message "belongs" to in the original delivery into the multidrop mailbox. In that case, I think, you need to work with the manager of that mailbox to get them to add a distringuishing header, e.g. Delivered-To:. Or you need to avoid multidrop altogether, and change the domain's DNS so that mail is delivered via SMTP.

I notice the 'Delivered-To' of 'pop3@...'. I don't understand that. Perhaps you can explain it.
