Creating new users with an old name: deferral: Unable_to_switch_to_/home/phr:_access_denied._(#4.3.0)/

People,

I had to do a lot of housecleaning on my server and now when trying to 
create a new user with a name that has existed previously and then 
mailing that user locally I get this:

@400000005c8a03630d6c68b4 delivery 13: deferral: 
Unable_to_switch_to_/home/phr:_access_denied._(#4.3.0)/
@400000005c8a03630d6c7084 status: local 0/10 remote 0/20

If I create a new user with a name that has never existed before, then 
the user receives mail as normal - there are no difference in 
permissions etc on the Maildirs for each type of new user.

I have made sure there are no issues with these files by cleaning out 
old stuff before creating the new user:

/var/spool/mail/reused_old_user_name
/home/reused_old_user_name
/etc/subgid
/etc/subuid
/etc/passwd
/etc/shadow
/etc/group
/etc/gshadow

- what else could be causing this problem?

Thanks,

Phil.
