Postfix/Dovecot Error: Permission Denied

[abednegoyulo]

I am having trouble right now with my postfix/dovecot configuration. The current status is: I can send to another mail server (yahoo.com, google.com, etc) using my server but I cannot receive mail on my server using another server(yahoo.com, google.com, etc) and my server itself(using a virtual account and sending email to itself).

After days of troubleshooting, google search, and reconfiguration, my current configuration is:

I use the "Test Account Settings" feature of outlook 2003 and it indicated "All tests completed successfully. I have checked the logs after testing with outlook 2003 and this is what I got:

The thing that is currently the pain in my head is the part where it says "Can't open log file /var/log/mailinfo: Permission denied". As of now I am in a dead end situation (I think) because I cannot troubleshoot why my mail server fails to receive emails because the useful part in logs are not being written on to it because of a Permission Denied error which is actually written to the same log file.

Did I missed something in the configuration? Wrong value? Something that should have been added? Something that should have been deleted? Please help me get out of the "Permission Denied" problem so that I could go on with troubleshooting the send/receive of mails.

Thanks!!!

Sorry, I mixed up errors in my head and after reading again the new errors it was now clear to my mind that it is not trying to write to maillog but to mailinfo. It was the previous case but now it is different.

Edit: Ok i finally found the user that is trying to access the log file. I can now read useful info from the logs for trouble shooting.
