                          <div>Sorry, I have checked before I wrote
                            first post. Based on docs - the path should
                            be in /etc/dovecot/dovecot.conf or
                            /etc/dovecot/conf.d/<a href="http://10-mail.co">10-mail.co</a><wbr>nf (I
                            have Ubuntu 16.04 LTS). I have some familiar
                            lines in 10-mail.conf:</div>
                          <div>#mail_attachment_dir =</div>
                          <div>#mail_attachment_min_size = 128k<br>

                          </div>
                          <div>but all these lines are commented out. So
                            - in theory - dovecot does not store
                            attachments anywhere but when I log into
                            i.e. Roundcube, I have there mails with
                            attachments. In Maildir/cur I see formatted
                            files related with specific emails. These
                            with attachments have specific hash at the
                            bottom of content. As we could suppose they
                            are hashed by sha1. But still no idea where
                            are real files, which I can download after
                            login to mailbox.<br>
