Hi Subramanian,
From the log:
Obsolete setting in /etc/dovecot/dovecot.conf:103: 'pop3s'

The newer version doesn't support that anymore, you have to update your config to match that.
You will find more info on that upstream, but in full that message usually is "protocols=pop3s is no longer necessary, remove it".

So fixing that up should be trivial.

Thank you for your report.

This looks like a local configuration problem, rather than a bug in Ubuntu.

You can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Since we use this bug tracker to track bugs in Ubuntu, rather than configuration problems, I'm marking this bug as Invalid. This helps us to focus on fixing bugs in Ubuntu.

If you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.
