I believe you should make those permissions 750, so the execute bit is present on both user and group. This may not be strictly required because the user is likely to always be vmail, but it fits better with POSIX conventions.
It's very odd that a directory would be created without the execute bit set wherever read permissions are granted. I hope this is an isolated incident and not a bug.
Here is a more verbose explanation of what the execute bit does on a directory:
"Execute permission on a directory is sometimes called search permission. If you found a directory that gave you execute permission, but not read permission, you could use any file in that directory. However, you must know the name. You cannot look inside the directory to find out the names of the files. Think of this type of directory as a black box. You can throw filenames at this directory, and sometimes you find a file, sometimes you don't."
I found this explanation here:
