<div>conversations.db initially was used to keep an index of email<br></div>
<div>conversations (e.g. the threaded views typically found in most email<br></div>
<div>readers nowadays). But today it also helps for most use-cases where<br></div>
<div>we need to keep track of messages across mailboxes (e.g. if you have<br></div>
<div>two copies of an email in two mailboxes, you'll see that reflected in<br></div>
<div>conversations.db). It confusingly is still named conversations.db for<br></div>
<div>historic reasons. But for any recent (v3) Cyrus IMAP installation,<br></div>
<div>including Xapian and JMAP, it's a very critical piece in the puzzle.<br></div>

<div>Ok. Thanks you.<br></div>
<div><br></div>
<div>Still one question, I see in the configuration file<br></div>
<div><br></div>
<div> conversations_expire_days : 90<br></div>
<div><br></div>
<div>why do I need to keep those information during 90 days ? For example what<br></div>
<div>would be the impact if I say<br></div>
<div><br></div>
<div> conversations_expire_days : 7<br></div>
<div><br></div>
</blockquote><div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">The bit which is expired is the mapping from message-id(s) to conversation id. If you set it to 7 days, then if you receive a reply to an existing message more than a week later, it won't detect that they are related.<br></div>
