Dear All
I apologize for asking an un-relevant question here.
I just need some pointer if somebody has already faced this issue.

I had successfully installed drupal 7, posfixadmin. I was able to login to postfix admin and create email ids etc.

In something broken (not sure which one caused the issue), I am experiencing below problem with postfix admin. In between I have added boost , memcache etc for performance.

1. I am able to access domain/mailadmin page.
2. I can create admin accounts at domain/mailadmin/setup.php
3. I can see the admin login page by access

But when I enter my postfix admin mailid, and password (i am 100% sure these are correct), it goes to a page domain/login.php and then says "Page not found".

My question is why it is redirecting wrongly to domain/login.php.

Kindly help me.

Please note that I have all other things working like amavisd, dovecot etc, I am able to send recv mails for accounts that I created previously.

Regards
