Those are the files I deleted in the last message exchange :-( in
order to stop all queud message from going out. I did however save the
first and last rejection which contains header information - the bad
new there (too) is that I saved them in a Squirrelmail folder and SM
is now not responding without MySql running, although I didn't realise
there was a dependency there(?).

Having examined the headers I noticed the emails were coming from a
(randomletters)@yahoo account and being sent to (randonletters)@yahoo
and hotmail. The large bulk were in the queue undeliverable but it
looks like at least a few hundred go through.

I had already tried that trick - no difference, it just creates a new
file when I try to restart.
The error seems to be:
/usr/libexec/mysqld: Can't find file: './mysql/host.frm' (errno:13)
but I haven't tracked that one down yet
