Is it possible for root user to read Dovecot IMAP users' email messages?

[cbj4074]

I am wondering if it is possible for the root user to read individual Dovecot IMAP users' email messages, without knowing each user's password.

We have a need to follow-up on customer complaints related to SPAM. Basically, we need to see the SpamAssassin headers for the messages in question.

If there is a way to do this that does not require access to the user's IMAP account?

It seems like this information could be acquired from a log instead, but sifting through log entries (especially after log rotation has occurred) seems like a nightmare. Furthermore, I can't seem to find a SpamAssassin log anywhere. Is logging off by default? And if so, does spamd need to be enabled to use it?

# Change to one to enable spamd
ENABLED=0

How do other folks handle this situation?

Thanks for any insight!
