does the contents change every 5 minutes? if not, then don't use the
file directly:
dump to a myrelaydomains.last file.
then have a script to compare this to myrelaydomains (the file used by
postfix)
if they differ, then overrite the latter. if they don't, do nothinging
as for dumping mysql, you can also have a date field in your mysql table
to tell if something has changed in the table.
