Can you please confirm that it won't cause any problem if we put
comments at the end of config lines?

No, I can't.

Example:
file: /etc/postfix/virtual
postmaster      postmas...@example.com # this is a comment

$ cat virtual
postmaster      postmas...@example.com # this is a comment

$ postmap -q postmaster virtual
postmas...@example.com # this is a comment

That doesn't look problem-free to me.

From man postmap(1):

INPUT FILE FORMAT
       The format of a lookup table input file is as follows:

       •      A table entry has the form

                   key whitespace value

       •      Empty  lines  and  whitespace-only lines are ignored, as are
              lines whose first non-whitespace character is a `#'.

       •      A logical line starts with non-whitespace text. A line  that
              starts with whitespace continues a logical line.

It doesn't mention that parts of a line after '#' are ignored when the '#' is preceded by non-whitespace characters.

We need to know this because of automation reasons.

Thanks!
