Need help deduplicating messages fetched with getmail into dovecot mailbox

[Gabriel Kaufmann]

Hello again,

I was able to workaround the getmail issue producing dublettes using
Sieve-Filter to find and discard dublettes. I was using this Rule-Set (I
found somewhere else in Internet). I only have sometimes dublettes now,
but not as worse as before (every mail twice!).

> # Track duplicate Mail-Deliveries
> require ["duplicate", "imap4flags"];
> if duplicate :header "message-id" {
>   discard;
>   stop;
> }
>
> keep;

Best regards
