<p dir="auto">When seeing duplicates in All Messages (or other smart mailboxes) then it's always a good idea to enable the “Source Mailbox” column in the message list. This will tell you exactly in which IMAP mailboxes these messages are located.</p>
<p dir="auto">In most cases, the explanation is one of the following two:</p>
<ol>
<li>Google (Gmail) which does not really support IMAP, but their own variant of IMAP with different rules. I've written about this (including how to deal with it) in this manual page: <a href="https://manual.mailmate-app.com/account_setup#gmail" style="color: #3983C4;">https://manual.mailmate-app.com/account_setup#gmail</a></li>
<li>Some SMTP servers have the non-standard behavior of saving a copy of sent messages in an IMAP folder (within the IMAP account which uses the same login credentials as the SMTP server), but MailMate also saves a copy. Depending on settings these might end up in different IMAP mailboxes.</li>
</ol>
<p dir="auto">Let me know if neither of the above explains the problem.</p>
