Greetings!

I recently discovered that postfix implements mailbox quotas with an rlimit.
First off, let me say, I think this is a good idea since child processes
can't accidentally stray over the limit during procmail, etc.

However, I think this limit is enforced too stringently.

Of particular interest to me is being able to access a database during the
delivery rule of a procmail filter. If a delivery rule opens the database to
do some processing, it will die with SIGXFSZ even though the mailbox limit
is observed. This is because a RLIMIT_FSIZE applies to all files and uses.

I believe that filesystem-level quotas are what should enforce a 'hard' disk
quota. Thus, I would prefer:

- rlim.rlim_cur =3D rlim.rlim_max =3D limit;
+ rlim.rlim_cur =3D limit;

Then, applications which really know they should be avoiding postfix's
rlimit could still operate inside it.

I understand that root can change this limit, but as a user, there is little
one can do. This is the position I find myself in.

Please remove the hard limit, but leave the soft, and I think postfix will
be more widely useful under more arcane mail configurations.

Thank you.
