/home/vmail/<URL:http://epopen.com/system>epopen.com/system listed at above section of Current Maildir information.


Thanks you a lot.

The HTML formatting in your mail makes it hard to read it on plain text E- mail readers. You should turn off HTML E-mail when sending mail to technical mailing lists.

It's difficult to review the technical data in your mail, because of the garbled HTML. The only thing I can suggest:

1) Find the process that's listening on port 143:

/sbin/fuser -n tcp 143


2) Attach strace to it:

strace -s 256 -o /tmp/strace.log -f -p <pid>

This will capture all system calls from the connection request. grepping the captured log file for

chdir
setuid
setgid

will indicate which system userid and groupid the imaplogin and imapd processes eventually run as, and which directories they eventually chdir to. You should expect to see the logged imaplogin and imapd child processes drop setuid/setgid, then chdir to the home directory, and the maildir. After the SELECT command gets received, the subsequent system calls should indicate which file/directory permission's are a problem.
