MailStore Home has no specific mechanisms to remove visible duplicates,
because we have to distinguish between visible and technical duplicates.
MailStore Home stores mails in a database. It therefor splits mails into their components (“mime parts”). Every unique mime part is only stored once. If an attachment or text part appears again later, only internal pointers are created. The actual part will not be stored again. This applies to every mail that comes in multiple times, even when parts are quoted or come from different sources. That is the reason why the archive only grows as little as possible.
Wherever a mail with its parts appeared it will be visible again. This includes every CC, every quote, every source. This actually has a well thought reason:
- We never know which one is an unwanted duplicate. Deleting a mail coming from Source A and keeping the same coming from Source B could be just the wrong way around. MailStore Home cannot make these decisions for you.
- Is it a necessary duplicate or not? Possibly the mail was sent to address A and address B. Even though it is identical, you need to comprehend who received this mail. It could be rather a coincidence that you archive address A and B to the same system.
Completeness. Even though laws concerning proper archiving usually apply to commercial use and are certified to be concidered in MailStore Server, MailStore Home as an offspring of Server also offers you wide parts of this philosophy.
Have you been sent this mail twice? Did it come from separate sources? No matter what the initial reason was, we mirror this activity to provide a complete overview of your communication. If you see something twice, then it came in twice.
To a conclusion we cannot make these global decisions for you.
A program cannot even make one single decision the way a living person would do.
Only you with the appropriate experience can evaluate whether a certain mail needs to be displayed or not.
From this point of view MailStore Software decided not to gamble with automatic deletion rules for duplicates.
In an archive, a few mails too much is always better than essential ones missing by accident.
