Duplicated messages

[Mark Adams]

An update to this, the "2 or 4" duplicates showing in the exim log look
like they are actually just separate deliveries to other addresses, so not
duplicates. In 1 example there is a single email with 2 recipients (2
entries in exim log) that has over 1500+ entries in the mailcleaner DB. It
looks like this email hasn't been delivered to the recipient at all either.
