yesterday=`date -d "1 day ago" +%y%m%d`
for server in serverA serverB serverC; do
  ssh $server grep "$yesterday" /var/lib/mysql/mydb.err
done | mailx -s "mydb.err for $yesterday" me@example.com

cat of single files, and temporary files, should be avoided.

Running this from cron left as a minor exercise.

cat -n and grep

I am not sure if using cat -n is the most efficient way to split a file into multiple files, one file per line in the source file.
