This idea fits the data quite well. It's a 64bit system though. That means the overflow would likely be in postfix, doesn't it? Yet Wietse points out that "File too large" is a message that comes from the kernel. I didn't run strace at the time this was happening, but perhaps I can try to reproduce it now. Thanks for your replies. Vince
