As I'm still suffering from the above named problem - I even copied all the configuration from another, well working server - I'm coming up with the results of stracing "submit":

This is when I try to send mails using apache (sending mail doesn't work):

Process 28391 attached - interrupt to quit close(12) = 0 flock(10, LOCK_UN) = 0 close(10) = 0 munmap(0xb7cef000, 135168) = 0 brk(0x80bf000) = 0x80bf000 exit_group(1) = ? Process 28391 detached

This is, when I'm calling the mail script by hand (command line) - when sending mail works:

Any further ideas?
