Hi All,

Thank you for your replies and Suggestions. But, I still not clear on my question. But It's live production server. At present I cannot make any changes to it. That will take a long process to make any on this server. At present my concern is,

To my server (dovecot, postfix, POP3/Imap protocol), I am getting the emails in my dovecot structured directory "Maildir/new". 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.

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? This is my current issue.

I am sorry for more concerning you guys asking the same question again and again. I am trying find the exact/correct answer on my current issue. I am new to this environment and new to dovecot/postfix also. working from last 3 to 6 months. This environment was designed by some other guy who left the company. I had to take this responsibility to support. I am kind of bit struggling. Please help.

Thanks,

Kishore Potnuru

Hi,

With dovecot 2.2 you can log some events with mail_log plugin.

Hi Benny and Dovecot,

Thanks for the reply.

Actually my question is, is it possible to verify anything now whether the email has been pulled by application/server from the "Maildir/new" or "Maildir/cur" folder in my POP3 server? at present I am not using lmtp yet.

When I configured the outlook to access the one of the email box in the server, I get the email. But do we have any log in POP3 server, stating the email has been to sent to Outlook?

Thanks & Regards,
Kishore Potnuru
