No need for spaces after >. The issue with the above
example is that the HERE-DOC includes "`" chars which bash
tries to interpret. It should display an error like this
when you run it:
-bash: bad substitution: no closing "`" in `
To fix that, use:
cat >dovecot_mysql.te <<\EOF
...
The change is the \ preceding EOF, telling bash to not
perform parameter/command/arithmetic expansions on the
HERE-DOC contents.
