[tpop3d-discuss]Permission problems with tpop3d

[Rob Fulton]

Hi,

We have setup tpop3d with exim and maildirs, all of the user details are 
loaded from a mysql backend, it is currently working happily for over 1000 
users except for a small problem of permissions.

None of our users run under local accounts on the system, their mail is 
stored in /var/spool/mail/username/.... Ideally all directories under 
/var/spool/mail should be owned by user mail, group mail. Files should be 
read/write user and directories should be read/write/execute user. 
Currently however we must run everything with group permissions set the 
same as user permissions on the data, i.e rw_rw____ for files and rwxrwx___ 
for directories. Tpop3d and exim both run as user mail.

If we try and run with the more secure permissions, we get the following 
errors in the tpop3d.log :

maildir_build_index: opendir(new): Permission denied

This fault appears to be caused by the opendir call in maildir.c, as far as 
we can tell, if the directory isn't openable as group mail, the call fails, 
even if the actual server can open it due to it being openable by user mail.

Has anyone come across this problem or a fix?

Regards
