URGENT: Problem starting Postfix "open directory defer/r/r: Not a directory"

[binover]

Hi guys, today I start my day looking how the postfix in one of my servers doesn't start.:mad:
This is the error:

"Starting mail transport agent: Postfixpostsuper: fatal: scan_dir_push: open directory defer/r/r: Not a directory"

I'm looking for it in inet but I could'n find nothing usefull.

Any data will help. thanks!
