Then you are unlikely to catch it. Also the strace would need to be
"strace -f" in order to include the child "postdrop" process.

Perhaps you could create a separate Postfix instance (that you don't
even start) and submit mail to it in a loop, but perhaps the error
is content (file size?) dependent.

Switch back to ext3 and if the problem goes away, stay with "ext3".

If my response solves your problem, the best way to thank me is to not
send an "it worked, thanks" follow-up. If you must respond, please put
"It worked, thanks" in the "Subject" so I can delete these quickly.
