Hi, we have the issue, that some(!) e-mails we receive are duplicated when processed by dovecot and stored to the users inbox. The mails are binary identical, same message ID, same size etc. diff sees no difference ?. For now we only see that it happens do small mails max. +- 5k in size. And in dose not happen for all mails, but some are spam, some are internal mails some are newsletter which are expected?. and it happens for different users. Dose anyone have/had a similar issue? Any suggestion or idea would be helpful. Thanks . G?tz -------------- next part -------------- A non-text attachment was scrubbed...

Thanks . G?tzHi G?tz, I've not had any similar experience but I thought perhaps to suggest if you try to analyse the dovecot and mail transfer agent logs when such email arrives and try to find what happens? It could be a sieve script copying emails to the recipient or something wrong in the MTA configurations that has nothing to do with Dovecot! Zakaria.
