Once the person/application (example: Microsoft Outlook) read the email, they are moving to "Maildir/cur". If they are deleting the file from Outlook, that will be deleted from the "Maildir/cur" folder also. I have Outlook as an example here. few email boxes are accessed by Outlook and few more email boxes are accessed by an application, where they configure in their application/outlook, to point out my server to read/access the emails. </div><div class=""><br class=""></div><div class="">I am repeating the same question again, From our server (where postfix, dovecot with pop3/imap protocol installed) knowing any ways (logs, incidents,alerts or any) that Outlook or application read/accessed/deleted the email which is in "Maildir/new" or "Maildir/cur" folder?

Configure it to log at least "delete undelete expunge" events to log if that outlook deletes the mail. See <a href="https://doc.dovecot.org/configuration_manual/plugins/mail_event_logging/" class="">https://doc.dovecot.org/configuration_manual/plugins/mail_event_logging/</a></div><div><br class=""></div><div>also if you want to check if that outlook does read the mail (ie. mail gets moved from new to cur) you need to configure imap_logout_format and pop3_logout_format to show number of mails fetched. see: <a href="https://doc.dovecot.org/settings/core/" class="">https://doc.dovecot.org/settings/core/</a></div><div><br class=""></div><div>Sami</div><div> </div><br class=""></body></html>
