I know mutt uses atime to detect new messages. But there are better and
more reliable ways to do this.

There are people who prefer noatime over relatime.

Using an existing time stamp for creation time is a bad idea IMHO. But
when doing this use the least important one. Which is atime. For example
ctime is used by backup programs.

Anyway when we want to support creation time it should be an additional
time stamp.
