Hi Viktor,
You are right, for some reason my system has some troubles with
fsspace("/var/spool/postfix", &fsbuf). Possibly, Bastian is right
about my kernel. But I just don't how to fix it.
Any way, Postfix code is OK, and the workaround with
`fsspace("/overlay", &fsbuf)` satisfies me so far.

Well, I found it!
If I pass change `fsspace(".", &fsbuf);' to `fsspace("/", &fsbuf);' it
works, no oopses, and the messages are received without problems. I
will make some stress tests later.
So the remaining question is what "." in smtpd context mean? Is it the
dir postfix has been started from?
Hi all,
I have investigated the problem a little, and here are some results:
First of all, it has nothing to do with memory consumption. The smtpd
crashes on statfs() in fsspase() function, which is called from
smtpd_check_queue() to check available free space on current
filesystem for a queue.
