Serhiy Storchaka added the comment:

st_nlink is not related to the number of messages in a folder. It is a number 
of hard links.

If the filesystem supports hard links counting for directories, every directory 
(except /) has at least two links: one from its parent directory, and one from 
itself (via "."). Every subdirectory adds yet one hard link via "..". 
Non-directory files don't create hard links.

Typical mail folder can contain thousands of messages and none or only a few 
subfolders. Subfolders (if there are any) usually are created before messages 
and hence encountered first in directory listing. Hereby the optimization can 
have significant effect.

If there is a real case when st_nlink != 1 and is less then a number of 
subdirectories + 2, we should consider removing the optimization.
