You are right, I've just had a look at the documentation.
That's a serious design flaw in the milter API.  :-(
Brain-damaged, if you ask me.

However, it seems like the xxfi_abort callback is called
when the milter is about to terminate.  Is that correct?
Can't it be used for dumping the DB?

After all, the dumping upon SIGTERM _is_ working fine on
FreeBSD 6, so there must already be a way to do it.
I just wonder why it doesn't work on some other operating
systems ...  What's the problem with those OS?  Do they
have a buggy POSIX threads implementation that doesn't
handle signals correctly?

Best regards
