How long ago was that? I had the precise problem and had been told that particular bug has been fixed. My problems were ~5 years ago. Except that I'm never going to use it anyway because I just can't force myself to trust it. I've used Postfix under ext3, ffs(openbsd), ufs(solaris) and never had a single problem with any of them. ext3 gets the bonus for being (I think) the only one of those to be journaled. -B
